1. Spraying water spray When the surface spray is medicated, the water can be sprayed off immediately to wash away the residual pesticide on the leaves. When the soil is phytotoxic, the concentration of the liquid can be reduced by draining the water to reduce the harm.
2, neutralization treatment First of all, to understand the physical and chemical properties of the pesticides used, first spray water to wash off the residual pesticides on the leaves, and then according to the acidity and alkalinity of the drug for neutralization. For example, after spraying the oxidized omethoate, it can be neutralized with a stone sulphur mixture, a Bordeaux solution or an aqueous lime solution.
3. Buffer treatment For the medicinal agents, the corresponding drugs are used for remission. If the smear of copper sulphate is applied, the lime can be hydrolyzed with a spray concentration of 5%~10%. At present, the main agents used to relieve phytotoxicity are Xianke and Life 1. Natural halogen and so on.
4. Reciprocal treatment Remediation is carried out with a growth agent that is opposite to the phytotoxicity of pesticides. If you use paclobutrazol to control over-length, you can spray gibberellin to remedy
5. Applying quick-acting fertilizers For vegetables that are slightly phytotoxic, you can reduce the phytotoxicity by spraying foliar fertilizer or applying a quick-growing vegetable growth agent at the roots.
