Here are some ways to curb pesticide phytotoxicity.
1. Fully understand the basic nature of the phytotoxicity, strictly control the dosage and concentration, select the correct period and method of use, and do not increase the dose and frequency.
2, understand the quality of the drug. If the stability of the emulsifiable oil is poor, and the stratification, precipitation or precipitation of many crystals, the water content of the powder is too high, it will produce different degrees of importance.
3, improve the technical level of pesticide application, reduce the possibility of the occurrence of the key.
4, pay attention to the environmental conditions at the time of application, the temperature is higher than 30, strong sunlight, relative humidity below 50%, wind speed over 3, can not be applied when the rain or dew is very large.
