【Apply in wind, rain and high temperature】

Wind spraying will cause the pesticides to float away; when spraying on rainy days, the liquid will be washed away by the rain to reduce the efficacy; spraying under high temperature will cause phytotoxicity and poisoning. Therefore, the best application time is: 8 am to 11 am, and 4 pm to 6 pm. The weather was fine and the breeze applied the medicine.

【Abusing pesticides】

Corresponding pesticides should be adopted according to the different types of crops, control objects and chemical properties, so as to prescribe the right medicine.
