The causes of phytotoxicity are more complicated, but in summary, there are three general points: one is to use pesticides or mix pesticides at random, the other is to use pesticides with deterioration and harmful impurities, and the third is that the application techniques are not yet mastered, and the application methods are improper. The time is not right, the concentration is too large, and the growth and development stages of unsuitable crops, as well as the weather of application, are selected during the application.
Method for controlling phytotoxicity
To prevent crop phytotoxicity, we must focus on five issues:
1. It is necessary to clarify the scope of use of pesticides, avoid the use of expired pesticides, and misuse pesticides, and do not mix pesticides at will.
2, carefully identify fake and inferior pesticides, do not buy and use pesticides without regular manufacturers, no normal labels, long-term storage, no normal packaging.
3. Understand and master the growth period and growth of crops, and do not apply drugs during sensitive periods of crops.
4, pay attention to the weather application, to avoid high temperature in the summer noon or when the rainy temperature is low.
5, rational use of the application of technology, the concentration of the drug should not be too high, liquid pesticide spray evenly, to avoid multiple spray.
