VEF UN KO

It belongs to the light drone helicopter class. It can be used to perform aviation chemical works. System of measures of protection against pest, diseases and weeds is a mandatory part of any culture growing technology and reserve of important harvest increase.

Diseases, which harm during vegetation, quite often cause also damage of the stored production.

Each year, losses caused by pest, diseases and weeds reach at the average 20-30% of the potential harvest. About one third of the losses reasons is diseases, which, during their massive development, reach even a half and more (for example, what rust, potato phytopthora parasitis, sunflower stem rotting etc.)

Chemical protection methods are based on use of various organic and non-organic combinations, which are harmful to organisms.

Chemical protection methods are very universal and can be used against the most part of pest, diseases and weeds in all agricultural cultures and different used land areas, as well as they can be used to process warehouses, greenhouses, elevators and other structures. Fumigant use is also very important in disinfection of various materials, products and fodder.

Especially effective pesticide use is in horticulture, where chemical substances allow eliminating extremely dangerous pest, improving quality of production and considerably increasing fruit harvest.

Herbicides are very effective. Long-term experiments have proven that they considerably decrease costs of struggle against weeds and facilitate increase of agricultural harvest.

As it is a flying object, safety is an extremely important requirement. All electronic components of protection against chemical substances’ splatters were designed with drop-protection bodies. Control electronics consists of several processors, which permanently follow the components to ensure normal operation. In case of failure, the machine stops and planes above the spot.

The aggregate does not require highly qualified personnel.

Drone aircraft of VEF UN KO is recommended for use by experimental factory-farm enterprises and agricultural scientific institutes as a carrier to perform aviation chemical work.

Drone aircraft of VEF UN KO may be used to destroy plants containing marihuana and other narcotic substances by special narcotic combating unit.

Use of drone helicopter has a considerable privilege if compared to simple land treatment methods.
Helicopter’s control method is very simple
Helicopter allows more precisely and more efficiently using pesticides and herbicides in the specific sector
Distant use is safe to humans
Use of drone helicopter many times increases the amount of received harvest.

Drone helicopter VEF UN KO can process 40ha or more in a day! 1 hour – 6 ~10ha, 1ha treatment may last about six minutes.

Timely pest control. VEF UN KO allows performing effective spraying at the height of 3-4 meters above the culture reaching dot-to-dot spraying.

Chemical treatment, which is performed using distant control from the neighboring territory, without entering it – convenient and safe.

Allows effectively using different types of pesticides combining it with the method that is the most suitable for the culture.

Small dimensions and weight, easy to transport.

Problem of struggle against weeds could be resolved by herbicides.
