Weed Control for Wheat with DJI AGRAS T16

DJI AGRAS T16Wheat Fields

Differing from the MG Series, the Agras T16 is equipped with four pumps and eight nozzles, with an increased spraying speed of 4.8 L/min, an increased volume of 16 L, and a spraying width of 6.5 m. So, what are the optimal operation parameters when spraying wheat?


In March 2019, a team from Denong Commercial and Trading carried out weed control for 53.3 hectares of wheat using the parameters listed below:

Land Type



Xinxing County,

Zhucheng, Shandong


Lv. 3 North Wind

Temperature & Weather




The operation target is 53.3 hectares of winter wheat in Xiangu Farm of Zhucheng City, Shandong Province. The control target is broad-leaved weeds in wheat fields, mainly composed of flixweed and pickpurse. The weather was sunny, the temperature was 5°-17°C (Note: Spraying effect is susceptible to temperature. It is recommended to spray herbicide when the average temperature is stable at 8-10°C), with a level 3 northern wind which is suitable for spraying operations. (Note: winds stronger than Lv. 3 are detrimental to spraying.)

Weeds affecting local wheat fields are mainly broad-leaved, such as flixweed and pickpurse. The Ruichaomai herbicide of Dow AgroSciences was used for spraying.



Note: When diluting dissolvable granules, make sure to dilute them twice. Mix a certain amount of the herbicide with a small amount of water, and stir evenly until the granules are completely dissolved. Then, add the appropriate amount of water and adjuvant to the concentrate, mix them evenly, and pour into the spraying tank.




The results of the spraying were checked ten days after the operation. As you can see, most weeds in the winter wheat field were wilted and twisted. Weeds would turn yellow or die, while the growth of wheat was not affected. This was a successful operation, and the operation parameters and herbicide listed above can be used as a reference for routine weed control of winter wheat.
