In the agricultural production process, the use of pesticides has become the most common behavior. Whether it is food crops, melons and vegetables or fruit garden wood, the use of pesticides to control pests and diseases and other harmful organisms provides a solid foundation for agricultural production. If the pesticide can not be used properly, it may cause phytotoxicity, which will seriously affect the normal growth of crops and fruit trees. Today, China's pesticide network Xiaobian for everyone to explain how to prevent phytotoxicity:

For the insecticide chlorpyrifos, it can not be used in the seedling stage of melons and lettuce to avoid the occurrence of phytotoxicity. Especially in the seedling stage of watermelon, it is absolutely impossible to use chlorpyrifos. There are also some organophosphorus pesticides, such as phoxim and triazophos, which cannot be used on melons. Imidacloprid is also not recommended. Pyrethroid pesticides, bio-pesticide avermectin and so on are relatively safe, but the concentration should be strictly controlled, otherwise it will easily cause phytotoxicity. In addition, sorghum is sensitive to many insecticides, such as trichlorfon and dichlorvos, so special attention should be paid to the use of sorghum.
For herbicides , acetochlor acetochlor must not be used on watermelon, strawberry or lettuce. Because acetochlor is used on watermelon, strawberry, and lettuce, it can cause phytotoxicity and even kill these crops. In addition, acetochlor should not be recommended on many crops unless acetochlor is registered on such crops, and when used on crops that have already been registered, there is no water accumulation, otherwise it is prone to phytotoxicity.
Tips for pesticide network experts: When using pesticides mixedly, it should be noted that acidic pesticides cannot be mixed with alkaline pesticides. Because the base and the acid are neutralized, the effect is affected after mixing, or it is likely to cause phytotoxicity.
