Second, the neutralization process. After the phytotoxicity of the vegetable, spray it in time, then understand the acidity and alkalinity of the pesticide and carry out neutralization treatment. The phytotoxicity of the sprayed omethoate can be neutralized with a stone sulphur mixture, Bordeaux mixture or aqueous lime solution to reduce the phytotoxicity.
Third, the buffer processing. That is, for the nature of the drug that causes the phytotoxicity of vegetables, spraying a certain drug to relieve it. If the smear of copper sulphate is applied, the lime water can be sprayed to relieve it; if the ginseng is sprayed, the boric acid solution can be sprayed for relief.
Fourth, mutual treatment. That is, using some of the opposite properties of pesticides for remediation. If the phytotoxicity occurs in the presence of paclobutrazol, the gibberellin can be used for mutual treatment because the former is a plant growth retardant and the latter is a plant growth promoter.
Fifth, chasing speed fertilizer. According to the law of vegetable growth, the vegetables that cause phytotoxicity can be applied with quick-acting fertilizer or spraying foliar fertilizer to enhance the growth of vegetables and reduce the degree of phytotoxicity.

Five methods for emergency treatment of phytotoxicity in vegetables
First, spray water and rinse. If the vegetables are sprayed with phytotoxics, spray the water in time and try to wash the leaves of the leaves. If the phytotoxicity caused by the soil treatment agent is misused, the field irrigation and drainage can be carried out in time to reduce the relative content of the drug in the vegetable plant.
