New technology can improve pesticide use efficiency

Low-volume spray technology The amount of pesticide applied per unit area is not diluted, and the pesticide stock solution is slightly diluted. The water consumption is equivalent to 1/5 to 1/10 of the conventional spray technology. Generally, the droplets of pesticides that can adhere to the surface of plant leaves are limited. When the amount of spray exceeds a certain limit, the fine droplets on the leaves will condense into large droplets, roll off and lose, and instead, the amount of pesticide attached to the leaves will be Drastically reduced.

The electrostatic spray technology can significantly increase the deposition amount of the liquid droplets on the surface of the leaves, not only making the front side of the leaves, but also allowing the opposite sides of the leaves and the hidden parts of the plants to be treated, thereby increasing the effective utilization rate of pesticides to 90%.

Pelletizing and applying technology For the water-soluble agent used in paddy fields, the pelletizing application technique can be adopted. The pellet can be evenly spread in the farmland, the working efficiency is increased by a factor of ten, and there is no pesticide drift. Contaminated adjacent crops.
