The nozzle is sprayed at a 45-degree angle 30 cm away from the plant, focusing on covering the area where eggs are gathered on the back of the leaf. It is recommended to operate when the dew is dry in the morning, for the better adhesion effect of the drug. Pay attention to wearing protective glasses to avoid drugs entering the eye.
