1 irrigation soil washing, so that a large number of plant roots absorb water, increase cell moisture, thereby reducing the relative content of soil, crop body drugs, play a role in easing the phytotoxicity.
2 In combination with irrigation and fertilization, cultivating loose soil in order to promote root development and enhance crop recovery.
3 The leaves suffer from phytotoxicity, and can be sprayed with fresh water several times in succession to remove or reduce the pesticide and fertilizer residues on the crop leaves.
4 The damage to fruits, flowers or squid on the local application or irrigation can be removed, and the fruit and the damaged shoots can be removed. If the main stem (dry) produces phytotoxicity, it should also be combined with fulvic acid fertilizer or clean water for disinfection.
5 Spray or combine with water to chase fast-acting fulvic acid fertilizer to improve the plant's ability to resist phytotoxicity, and at the same time promote the growth of crop roots.
6 spray regulators or hormones. Such as paclobutrazol or other inhibitors or delays overdose or 2,4 D overdose caused by phytotoxicity, can be sprayed gibberellin; copper sulfate injury can be sprayed with 0.5% quicklime; dimethoate spray can be applied 0.2% boric acid or borax Anti-dropping insecticide can be used 0.5% to 1% of the sugar solution every 3 to 5 days spray once, generally 2 to 3 days after the leaf surface will slowly begin to stretch.
