Several technical methods to improve the utilization rate of pesticides

Low volume spray method

When the application amount is constant per unit area, the pesticide stock solution is diluted with water and sprayed. The amount of water added is equivalent to 1/5 to 1/10 of conventional spray technology . The specific method is to replace the large-aperture spray of the conventional spray machine with a small-aperture spray with a diameter of 0.3 mm. This can reduce the loss of pesticides, save a lot of water, and significantly improve the control effect.

Electrostatic spray

A high-voltage static electricity generating device is installed on the spraying machine, so that the amount of the chemical spray applied on the surface of the crop blade is greatly increased, and the effective utilization rate of the pesticide can reach 90% to 95% .

Capsulized application

More suitable for paddy fields. Simply apply the processed pills evenly to the field, which can increase the efficiency by more than ten times compared with the conventional application method, and there is no pesticide drift.

Circulating spray method

A drug reflux device is attached to the opposite side of the conventional spray component. The drug solution not deposited on the target plant is collected and pumped back into the medicine box, so that the pesticide can be recycled, and the effective utilization rate can be greatly improved.

Roller smear

Mainly used for the prevention and control of systemic herbicides. The liquid medicine oozes from the surface of the medicine roll by a paint overflow made of a foam material capable of absorbing the liquid medicine, and the medicine roller only needs to contact the blade of the upper part of the weed to be effective. Almost all of the agent can be applied to the surface of the target plant without causing liquid spills and dripping .
