How to avoid pesticide phytotoxicity? Please provide guidance methods
To avoid pesticide phytotoxicity, you can refer to the following methods:
1. Fully understand the basic nature of phytotoxicity, strictly control the dosage and concentration used, choose the correct time and method of application, and do not arbitrarily increase the amount or frequency.
2. Understand the quality of the pesticide. For example, emulsifiable concentrates with poor stability that separate into layers, produce large amounts of sediment or precipitate many crystals, and powders with excessively high moisture content will all cause varying degrees of phytotoxicity.
3. Improve the technical level of pesticide application to reduce the possibility of phytotoxicity.
4. Pay attention to the environmental conditions when applying pesticides. Do not apply pesticides when the temperature is above 30, under strong sunlight, when relative humidity is below 50%, when wind speed exceeds level 3, or on rainy days or when there is heavy dew.
5. For pesticides that have never been used locally, a small-area phytotoxicity test must be conducted before use.
6. Pesticides with lost labels, no production license, no trademark, or without national approval and registration must not be used, so as to avoid phytotoxicity problems.
