Rating of the best models
In a variety of reviews of quadrocopters with a camera, a well-deserved place is occupied by the DJI Mavic Air model. It shoots with high quality and can be folded, which simplifies transportation on the road to the launch point and back. This version is supported by the good wind resistance and the presence of a number of automatic flight modes. Controlling the Mavic Air is quite simple and convenient. The device is designed for purely amateur use.
The manufacturer claims that it takes 28 minutes into the sky. Provided:
- Three-dimensional somersault function;
- Automatic maintenance of a given height;
- Management from mobile gadgets;
- Matrix 2 Mp.
To get around registration restrictions, you can purchase a UAV with a camera weighing up to 250 grams. The popular Syma X5C is good in terms of flight. However, his camera has a resolution of only 0.3 megapixels. After that, it makes no sense to count on panoramic shooting. The way out is partly to change the factory equIPment to more advanced solutions; shooting time in the air is 5-6 minutes.
Radio-controlled models are very good, but it is even better if the camera works by broadcasting an image to a screen convenient for the operator. In this category, the Hubsan X4 Star Pro H507AHT009 stands out, which is also relatively cheap when compared with other analogues of the same class. Despite the affordability of the price, there is such a compelling advantage as the GPS module. The Failsafe option supports automatic return or landing on autopilot when the charge is depleted. But such a UAV falls into the top for other reasons, among which the most important are the option of flying by points, maintaining altitude and following the operator.
Another drone with a high-quality broadcast camera is the WLToys Q323. The device is quite powerful: it can fly for at least 15 minutes. The FPV camera can be rotated 90 degrees by commands from both the remote control and the smartphone. The propellers and outer body are made of carbon fiber, which reduces weight and improves aerodynamic performance. The model is equally suitable for both beginners and experienced operators.
It is imperative to understand the mounting of the removing device itself. Biaxial gimbals most often stabilize the image in pitch and roll. The horizontal movement will still be very noticeable. However, this design is lightweight and easy to carry. The heavier and more expensive three-axis gimbal is equIPped with an additional motor; it allows you to get a more stable picture, but this is achieved by reducing autonomy.
Among them there are models with a choice of white or black cases, such as CEVENNESFE. It provides an automatic take-off and landing mode. Users can choose from cameras with a resolution of 3 or 5 megapixels. The device is designed according to the traditional cruciform scheme.
It is worth paying attention to the drone Mioshi 3D. Its mass is 0.28 kg. Flight time. up to 5 minutes; the charge is restored in 45 minutes. The radius of full control is 50 m.Synchronization before departure is required.
A good silent unit is the DJI Mavic Platinum. Quiet flight is ensured by a special design, where “rails with wings” are added. The design has also been improved with electronic adjustment. If you choose a waterproof quadcopter, then it can be the budget model JJRC H31. Splashes and even a short dive are safe for her.
When selecting devices with a barometer and a camera together, Syma X8HC draws attention (2000 mAh, 2 MP, flIPs, support for interchangeable cameras). Consider as an alternative:
- Pilotage Falcon X5;
As for underwater drones, we can recommend the following versions:
- Powervision PowerRay;
What does it consist of?
Classic flying drones include:
- Speed control systems;
- Electronic flight controllers;
- Housings (frames).
It is the frame that acts as the technical basis of the drone, and it is to it that all the elements are attached.
Any developers are diligently looking for a balance of lightness, impact strength and durability. Most often, the frame is made of polymers or light alloys. Many models use carbon fiber, fiberglass, and other substances. One-piece frame is rare, in most designs it is assembled from a number of parts and has channels for connecting electrical wires.
It is by the number of simultaneously processed signals that one can judge the perfection of the drone. The flight controllers are connected to sensors, according to the readings of which the flight parameters and some other characteristics of the environment are determined. There is always:
- Satellite navigation systems;
- Wi-Fi block;
- Rechargeable batteries.
As for underwater drones, their typical equIPment, in addition to the camera, includes:
- External waterproof case;
- Depth gauge;
- External lighting system.

Drone with Camera. This is not only a quadcopter, but other options as well. You need to understand what they are and what they are for. A separate topic is how to choose a good copter with a camera on the remote control; there are a number of other nuances.
What it is?
From the very beginning, it should be noted that a drone and a copter (quadrocopter) are not identical concepts. precisely, any quadcopter is just a particular type of drone. It has four motors and the same number of propellers. There are also UAV models with two, three, six or eight drives and propellers, but they are much less common. It is also necessary to take into account that not only flying, but also water and ground drones already exist.
The flying drone of various models looks more or less the same, the difference concerns only the size and features of the technical equIPment. One way or another, a device with a camera is designed to penetrate into various places where it is very difficult or almost impossible for the operator to get there. The control is carried out using the remote control or according to programs embedded in the on-board computer. Drones are designed to withstand atmospheric and other influences, which significantly increases their reliability.
Surveillance from air, water or land is used:
- In entertainment and research filming;
- For the needs of television, cinema and theater;
- Search and rescue and rescue operations;
- To protect a certain area;
- To conduct intelligence in the interests of military and law enforcement agencies;
- For visual inspection of power lines, railways, second long, remote, high-rise and hard-to-reach objects.
Many people fear that an aircraft with an aerial photography function is prohibited. This is not entirely true. To begin with, any such devices weighing from 0.25 to 30 kg are subject to mandatory registration. Flights at altitudes above 150 m are required to be declared in advance in the unified air traffic system. A drone can be launched even within the courtyard of an apartment building with the permission of the owner of this territory; in a number of cities Additional local approvals have been introduced.
The bans exactly apply to:
- Flights in crowded places;
- Flights where there are secret objects, and in their vicinity;
- Surveillance of people and organizations of any kind without their direct written permission, drawn up in the prescribed manner;
- Any flights that endanger the safety of other people and their property;
- Filming from the air at stadiums, fire departments, national parks and reserves, on the territory of dIPlomatic and consular missions;
- Filming of government buildings and objects used by them;
- Filming of places of detention, operational police officers in the performance of their duties, as well as photographs and recording of investigative actions;
- Filming at events with limited entry;
- Filming at the state border, in the border strIP and at crossing points;
- Photographing and filming at all objects of railway transport;
- Photographing at power plants of all types and power levels.
Consider the main types of drones with a camera.
The most important role is played by the view of the camera itself. Many models are equIPped with HD cameras. They are used for photography and shooting, as well as for terrain control. In amateur models, action cameras from large manufacturers are often used. Such versions can not only record, but also transmit a signal, which allows you to get rid of additional components. However, the transmitted image is compressed using digital aLGorithms, and after that its quality inevitably deteriorates, and it is no longer possible to talk about broadcasting in real time.
This is the name of the analog equIPment kits. In them, the signal is not compressed, but transmitted immediately in finished form. This is very valuable, for example, when there is a legal broadcast from a sporting event or other event that needs to be shown in full detail. This property is also useful for shooting in dense urban areas. Finally, FPV is the first choice of any Trained Pro.
From a consumer point of view, FPV equIPment is good:
- Minimal energy consumption;
- Relative ease;
- Increased reliability;
- Affordable cost.
In a number of models, designers anticIPate stabilized suspensions. over, even amateur photography without this function is unlikely to satisfy people’s needs.
Stabilizers are designed very carefully so that they work as efficiently as possible in conjunction with flight controllers and other drone components. The maximum that can be achieved by an unstabilized aircraft in flight is an image for distribution via social networks. And even there, the level of requirements is steadily increasing, and soon they will stop filming without stabilization altogether.
Such equIPment has long been used not only by professionals, but also by amateurs. It is prized, for example, by hunters and fishermen. And also it is willingly bought by repair services, which need to check the thermal characteristics of remote and hard-to-reach objects, by detecting heat loss in high-rise buildings.
But the gradation of flying cameras is possible not only by the type of cameras. The configuration of the UAV itself also plays an important role. Aircraft type drones are preferred when you need to study and photograph large areas. It is also suitable for visual tracking of land and water transport, for searching for missing people, for example. An aircraft UAV flies far, high and for a long time. Usually he acts according to the planned program in advance, and then returns.
Helicopter drones are needed for finer, more accurate work. They can be directed into a cave and into a tunnel, into a mountain gorge and into a forest, inside a building, and so on. These cameras also move relatively slowly, vibrate less and provide optimal quality of shooting. The downside is a significant limitation of the range and flight time; however, this problem is justified by the minimum requirements for take-off and landing sites.
The underwater type of drones deserves special attention. This is the name for hermetic complexes of mechanical and electronic equIPment, promising in terms of researching fresh and salt water bodies at different depths. The variety of underwater vehicles has grown significantly in recent years. All of them are distinguished by increased autonomy and vitality; the most advanced are autonomous and able to pop up if the connection is lost. The control takes place either through a special cable, or by closing the antenna in the buoy, communication with which occurs through a cable with neutral buoyancy.
How to choose?
If a drone is selected exclusively for an apartment, then you can choose the smallest models. Running such a technique on the street is, to put it mildly, reckless. A small gust of wind is enough to blow the UAV far away. and if it leaves the field of view, it is almost certainly lost. However, such devices perform much better at home. Among them, the Cheerson CX-10W and Hubsan X4 Н107С are well-deserved.
It is also worth understanding the choice of equIPment for FPV flights in the apartment. Manufacturers usually label these drones with the Tiny Whoop name. A good example of this is the Eachine E010C. The camera installed on it gives an overview of 150 degrees. The transmission of impulse to both special glasses and the display is guaranteed.
and more people are buying drones for selfies. They must be well equIPped. Some advanced models certainly have ultrasound and infrared sensors. Almost all of them are controlled via a mobile phone. FPV option is usually present; however, only a few self-drones fly for more than 6 minutes.
The ability of the camera to tilt plays a very important role in the selection of such drones. The option to return to the pilot by pressing one button, as well as the mode of maintaining altitude, are also useful. It is also necessary to assess at what distance it is possible to control the UAV; In fact, this is a more realistic range than that provided by engines and batteries.
But just choosing a device with a long range is not all: you should definitely take into account the difference in flight modes, which each manufacturer assigns at its discretion.
It is worth, for example, pay attention to:
How to use?
Controlling drones is very simple. and the most convenient is to use a dedicated remote control for this purpose. In its configuration, it resembles a conventional joystick. Anyone who has experience playing on consoles will figure it out without problems. Most often, the left control lever supports the vertical movement, and the right lever is used to direct the UAV horizontally. Advanced modern models can be connected to a smartphone. but in any case, you should carefully read the instructions.
The most difficult thing is to control the device in manual flight mode. However, it also opens up the maximum possibilities for the operator. It should be understood that additional stabilizers do not work in this mode. After that, you need to soberly assess your capabilities, using such functions only if you have experience.
Before the first start, it is imperative to prepare a backup battery. If the workout ends in the first 10 minutes, there will be no sense from it. The accelerometer, satellite navigator and other necessary components are also configured for launch. You need to have screws and other spare parts with you, which basically break. Having worked out the simplest manIPulations, you can switch to the stable flight mode; it is easier to manage in this case, and it is in it that many professional photographers and operators work.
By selecting the GPS navigation mode, you can set a route with the passage of preset points. This is very useful if you do not need to continuously monitor the movement of the apparatus. When such a program has been completed, you can turn on the telephone control mode. For this purpose, gadgets on Android, iOS are equally suitable. Live broadcast over Wi-Fi is transmitted to the device screen.
Trying to figure out right away to what practical height the drone rises, not too wisely. At the very beginning of its development, they are trained to take off, turn, distant a few meters. Do not start training indoors. It is much more correct to choose a flat area where flights will NOT interfere with anyone, and comes there in calm weather. Only after working in calm weather, having developed a sense of the drone, you can properly configure it to work in strong winds.
If possible, the drone should be launched in deserted places. Only experienced operators should direct it into the forest, lead it over the river, lead it into a cave, inside pIPes and other difficult places.
The standard cameras of budget UAVs are best replaced with more powerful models. To be dynamic, you need to adjust the flight of the drone itself:
- Tilting the camera down while climbing will show a dynamic zoom in the panorama;
- Lifting up and slightly twisting the camera from the very low position will create a feeling of dizziness;
- Raising the lens straight forward will ensure long-range and horizon-based shooting.

What is the quadcopter for?
19 August 2015
Quadcopter (from the English. Quadcopter. “helicopter with four propellers”) is an unmanned aerial vehicle with four propellers, which is usually controlled by a remote control from the ground. As a rule, a mini-camera is installed on it, which allows taking photos and filming in flight.
It is a pity that people do not fly like birds. Probably everyone dreamed of seeing their city from above, shooting from a great height, enjoying an unusual panorama. And this dream, thanks to such a wonderful invention as a quadcopter, may well become a reality.
Previously, drones could only be seen on the Internet or on TV, and most did not even think about purchasing them because of the crazy price. But over time, such gadgets continued to fall in value, and today more and more people can afford to buy a quadcopter with a camera. These devices are gaining popularity every day in many parts of the world. They are used in the Armed Forces, various from state and commercial organizations, and special services. Even the legendary Google company uses quadcopters in its work. Very often, with the help of such gadgets, clIPs, weddings and other events are shot. Quadcopters with a camera capable of broadcasting. They create the effect of being present during the flight, and also simultaneously records. This device can penetrate almost any, even the most inaccessible places.

Quadcopter buying advice
When purchasing a copter, you should not be tempted by a too low price. There are many cheap imitations on the market today, most of which are conventional RC helicopters with no camera attachment.
The undisputed leaders among professional quadrocopters are DJI Phantom gadgets. Yes, their price is quite high, but worth it. The most famous and impressive ones were captured with the help of the copters of this brand.
To make the best choice, you should know the basic characteristics of quadcopters. They can record either simply to a flash card or transmit an image in real time over a channel. The second option will give you the opportunity to fly in the first person, which of course is a great advantage. If you are NOT too limited in funds, it is better to get a model with a real-time camera.
The number of control channels can also differ in a quadcopter. For each of them, one of the parameters can be transmitted, for example, the speed can be changed. In general, the more such channels in the characteristics, the better.
The quadcopter can be sold with or without a gyroscope. A gyroscope is a small sensor that monitors the stability and position of the unit in flight. It allows you to hang in the air with a crosswind. In the absence of a gyroscope, the copter can drift to the sides, as a result of which there is a risk of a raid on any obstacle. Therefore, it is advisable to purchase a model with such a sensor.
Pay attention to the distance and duration of the movement. Of course, the higher these characteristics, the better. Many models have a flight time of about 15 minutes, after which it becomes necessary to replace the battery. Some drones can fly longer. The flight range is determined by the control method. For example, with wi-fi technology, the flight range ranges from fifty to one hundred meters.
Is it possible to assemble a copter by yourself?
If you do not have enough duration or range of movement, you can try to assemble the quadcopter yourself. If you are willing to take risks, own soldering technology, are well versed in electronics and are ready to spend several months on it, you can hope for a good result.
However, you will not have a warranty on the copter, and not all components will be immediately compatible. Therefore, it is better not to waste time and effort, but to purchase a ready-made quadcopter.
A quadrocopter (aka a copter and a quadrolet) is a small flying analogue of a helicopter. It has four screws which rotate in the opposite direction. If we compare a quadrocopter with a conventional radio-controlled helicopter, then the first one has better smoothness of movement, as well as greater maneuverability. In addition, the drone has low noise levels and does not generate strong air currents. This allows you to use the device Not only for shooting in the air, but also indoors. Any lightweight camera can be attached to the quadcopter.

Types of quadcopters
Flying drones can be divided into several categories:
- Drones without a camera. The characteristics in quadrocopters of the budget segment are low, the models support a short flight range and are able to stay in the air for about ten minutes. You cannot shoot with their help, but you can just enjoy piloting and maneuver.
Cheap copters without a camera are usually bought for children
- Copters with a camera. Such models are more expensive, but they provide the opportunity to take photos during the flight.
Good image quality Provides drones for shooting with a resolution of 5 MP and higher
- For newbies. Inexpensive but very durable models are capable of surviving multIPle drops. EquIPped with brushed motors, the flight range is about 100 m, there is often a built-in acrobatic mode.
Starter drones usually come with propeller guards
- For lovers. Such models support shooting with a resolution of at least 720p and stabilization, are able to move 1 km away from the operator and stay in flight for up to 25 minutes. Usually capable of speeds up to 70 km per hour.
Amateur drones are equIPped with a GPS module and multIPle flight modes
- For professionals. The most functional drones support satellite navigation and shoot in 4K format. The image is transmitted to a smartphone from a distance of several kilometers or recorded on a memory card. EquIPped with numerous sensors, including obstacle tracking, are quite expensive.
Professional drones are more often equIPped with outriggers rather than built-in cameras
- Racing. Such models are intended primarily for maneuvering. On the device of racing-type quadrocopters, they show that the camera in them can be quite modest, but the speed of the drones is up to 120 km per hour. They are usually removed 1 km from the owner, many models support control via.glasses.
Many racing drones are streamlined
When choosing a flying drone, you should take into account exactly what purpose it is needed. for shooting or acrobatic stunts.
What is a quadcopter, what it looks like and what it is intended for
A quadrocopter is a relatively small aircraft controlled by an operator from the ground using a remote control or mobile device. Outwardly, the drone most of all resembles a miniature helicopter, since it also has an oblong body, a propeller and landing skids. However, most often there are several screws in the copter. from four to twelve pieces.
High-quality drones are capable of speeds comparable to that of a car
With very different photos, the purpose of quadcopters is mostly universal. First of all, they can be used as an interesting and exciting toy; any model is suitable for this. Both children and adults enjoy piloting a copter, giving it the direction of flight and even making turns in the air. Some drones are suitable for racing.
Of greatest interest are quadcopters with built-in or external cameras. They allow you to take pictures and record from above. They are used by professional photographers and amateurs, and expensive models are used in industry for a detailed examination of buildings and large objects.
How a quadcopter works with a camera
Of greatest interest are drones with built-in or pendant cameras, their capabilities are the widest. In terms of the internal structure, such devices practically do not differ from the simplest models. The difference is that in the main unit on the power frame there is also a small sensor or mounts for fixing external photographic equIPment.
Drone cameras from different price categories differ in capabilities. It is not only about image quality, but also about functionality. For example, expensive cameras are equIPped with adjustable focus, as well as a rotary mechanism. They can be directed in different directions, while NOT changing the position of the drone itself in space.
Drones can transmit and photo in real time for a short distance up to 1 km
Budget copters with a camera send photos directly to the operator’s mobile device. expensive models support memory cards that allow not only saving images, but also programming the route and behavior of the drone.
How the quadcopter is controlled
You can control the quadcopter in several ways. Budget models support only one piloting option, more expensive ones may offer a choice of modes.
Quadcopter range with camera
The range of a quadcopter usually does NOT depend on the presence or absence of a camera. What matters is the class of the drone as a whole. Budget models capable of 100-500 m distance can be equIPped with a built-in sensor, but its resolution rarely exceeds 2 megapixels. expensive drones with good cameras of 5 megapixels and more fly away on average 500-800 m.Professional devices with high cost and high-quality external photo equIPment support a range of up to 20 km.
Many drones can be piloted from a mobile. in this case, you need to install a special application on your smartphone. A control panel with exactly the same buttons as on a regular joystick will appear on the device screen. Communication with the copter is carried out via Wi-Fi, the device can transfer photos in real time to a smartphone.
The disadvantage of controlling the drone from a smartphone is a short range within about 100 m or a little more
What is and what is a quadcopter with a camera for
The quadcopter allows you to enjoy the control of flying machines or take pictures from a bird’s eye view. To properly evaluate the device, it is worth studying its features and types.
An interesting way to fly also requires the use of a mobile device. But in this case, the operator does not need to click on the buttons offered by special applications. The drone changes its direction of flight by tilting the smartphone. The method is very convenient for high-speed maneuvering.
When controlled by tilting the smartphone, the drone repeats the spatial orientation of the mobile
How a quadcopter works and flies
The princIPle of operation of a quadcopter is quite simple. Engines in the amount of four pieces or more, located on the beams of the machine frame, create a lifting force when turned on, and the drone takes off from the ground. There are several modes of action in motors:
- Simultaneous start of all engines. directly for takeoff;
- Side tilt. the rotation speed of the left or right pair of motors changes at the same time;
- Reducing engine speed to reduce lift, in this mode the drone is landing;
- Speed gain is achieved by changing the rotation of the rear or front pair of motors.
In general, the layout of the drone is very similar to the helicopter. But if a large aircraft maneuvers due to the inclination of the blade shaft, then the copter changes its position in space due to the difference in air flows on the sides. To rotate in place, you need to reduce the speed of one of the pairs of motors, in which case a reverse torque will occur, and the whole structure can spin around an axis.
The fewer blades in the drone propellers, the faster it is
In the hunt and in the army
Hunters use quadcopters to scout forests and monitor wildlife habitats. This is a safe way to track animals, moreover, this way you can shorten the time of their tracking by flying around the “hot spots” in advance. In addition to tracking, drones are also needed for shooting blogs from a hunt or for tactical purposes, for example, to evoke a reaction from animals and take them out into the open. We talked about how to choose a quadrocopter for hunting in a separate article.
What is a quadcopter with a camera in scientific language?
A quadcopter is a type of multicopter. The multicopter itself means “multi-rotor helicopter” or “multi-flight”. It is built on a helicopter design and has more than three rotors. In our days, the concept of “quadrocopter” has become very well established, as a designation for an aircraft, which is controlled remotely from the ground by means of a remote control.
Scientific terms and concepts related to quadrocopters are used mainly in scientific literature, reports and abstracts of students and dissertations. In our review with you, we will call a spade a spade, since we do not pretend to be a “Doctor of Science of Quadrocopter Technologies”. Let’s do without this fun.
Assistant with camera
Quadcopters are sold with or without a camera. For shooting from a height, I previously used special cranes or helicopters, and this is very expensive. It is worth noting that now this requires quadcopters with a camera or the so-called FPV system, which allows you to monitor the shooting process in real time. over, individual models allow you to change the shooting angle by rotating the camera.
It turns out that a quadrocopter with a camera significantly reduces the cost of the shooting process. Such a device is needed for journalists, bloggers, cameramen. Filming of SEPARATE wedding episodes is in great demand now. Such drones can automatically track the subject, which means that you can customize it and keep your blog, or shoot the plot from a different angle, if you are NOT the presenter, but the operator.
Thus, you bought the necessary model of a quadrocopter for shooting, you expand the range of services provided, if you are a photo or operator or embellish your blog.
Gimbal with camera
It is an essential part of any multicopter with a survey function. The pendant mount is used to connect the camera to the body of the apparatus. It can have multIPle axes (usually two or three) allowing the camera to rotate to capture images in different directions.
Often the suspension is equIPped with special damping pads, which are designed to dampen vibrations and provide high-quality stabilization at the hardware level.
The future of drones
What else are copters capable of and why do people need, besides entertainment?
Already today, such aircraft are quite successfully used to help construction crews in the installation of complex, composite structures, in agriculture, when filming BBC documentaries, and even for transporting people.
The last point can be considered a particularly interesting, revolutionary perspective in the world of UAVs. You can find a separate article dedicated to such large-sized drones on the pages of our website.
We hope the article was useful and informative for you. If so, Subscribe to and tell your friends / acquaintances about them on social networks. Have a good time with your first drones!
Greetings, dear reader of my blog. For a long time I have not published new articles, and today the day has come when I am ready to resume doing text reviews on quadrocopters under my editorial staff.
In this article, we will answer three questions that worry many novice drone users:
- What is a quadcopter;
- What cameras are there in quadcopters;
- What is the quadcopter for?
UAVs and modern legislation
Currently, at the legislative level, there are certain restrictions in the context of the application and use of quadrocopters. For example, each drone weighing 0.25. 30 kg is subject to registration on the territory of the Russian Federation and implies a pilot’s flight license.
In addition, you will have to obtain a flight permit, which will require a certificate of airworthiness, access to the operation of the air GoPro and certification of the legality of UAV piloting. If you plan to shoot in certain regions, you will also need an appropriate permit.
All about jewelry, precious stones and metals
A multicopter is an alternative, variant of quadrons, surpassing them in the number of motors. Its main rotor rotates diagonally and in opposite directions to each other.
Multicopters differ among themselves by the number of motors. In modern practice, in addition to three- and four-propeller models, there are hexacopters and octocopters with 6th and 8th propellers, respectively. The number of screw elements by and large determines the capabilities of the vehicle’s peak loads in terms of mass, that is, how much weight it can take on board.
The quadcopter is also needed to ensure the safety of the facility. Some security companies use them to monitor and patrol the perimeter of the territory. This is a safe and effective way, especially if it is equIPped with a night vision device or a thermal imager instead of a camera.
Drone for security
But, as the saying goes, “laziness is the engine of progress” and resourceful people came up with a quadcopter to walk pets. You can watch your pets from the comfort of your home.
Farmers have also found use of a quadcopter, they help Not only keep an eye on the animals, but also drive the animals into the herd. In agriculture, drones are used to control the rIPening process of crops, fertilize, and also to combat pests.
