Treatment of The thrips Liothrips Karnyi on pepper using DJI AGRAS T20 in Vietnam

 

 

 

*1. Purpose of the Spray

 

The spraying team used the DJI Agras T20 to control thrips and take care of flowering for pepper plants. The purpose is to help stamp out the thrips epidemic quickly, and ensure that the production of pepper is successful.

 

 

 

*2. Info of the Environment
 

Date of Spray	May 12th, 2021	Location	Dak Nong district
Type of Terrain	Hill and mountain	Temperature (℃)	28oC
Total sprayed Area(ha.)	28 ha	Humidity	N/A
Wind speed(m/s)	3-7km/h	Wind direction	N/A

 

 

 

*3. Operation Parameters

 

 

Type of Drone	DJI Agras T20	Firmware Version	0023
Operation mode	Route plan--Effective	Operation Speed	4m/s
Operation height(from the top of the crop)	2.5-3m	Line spacing/width/	5-6m
Liquid amount sprayed per hectare (or per MU)	40 lit	Nozzle type	RX110015VS

 

 

 

 

The above parameter helps the drug to be sprayed evenly from the top down because the pepper tree has a cylindrical shape, and the slow flight speed helps the propeller blow the chemicals down to the base of the pepper. The foliage of pepper is thick from the top down in a cylindrical shape, so we set the spray width as 5-6m and the speed is 4m/s to help the propeller blow the chemicals down to the base of the pepper. Plants absorb nutrients on leaves faster and more efficiently.

*4. Info of Chemicals

 

 

Chemical commercial name	Formulation	Active ingredient and the percentage	Chemical amount(g or ml) used per hectare
RONALDO		Buprofezin: 90g/l + Dinotefuran 10 g/l + Isoprocarb 400g/l	0.5kg/ha
Calcimax B Fertilizer		Boron (B): 2000 ppm, Zinc (Zn):210 ppm, Iron (Fe): 500 ppm, Nitrogen (N) 2,5%, Calci (Ca) 4.0%, pHH2O 5,7	3.0 lit/ha
Senca Fertilizer		Protein (Nts): 11% Magnesium (MgO): 16% Humidity: 1%	1kg/ha

 

 

 

 

 

*5. Briefly compare the difference between drone, manual, and other traditional equipment in this case

 

Pepper is a tall plant which is hard for the traditional spraying method to spray, with not only the human body comes into direct exposure with the drug but the drug also residue will accumulate in the soil. Using drones to spray pesticides solved the above influence.

 

 

 

*6. Conclusion

 

Before using DJI Agras T20, the owner doubted the effectiveness of the drones. But after 15 days of following the results, the pepper garden simultaneously flowered and bloomed regularly. Garden owners are quite satisfied with the effectiveness of using drones.
