Spraying water and pouring If the vegetable leaves are tainted, spray the vegetables with clean water and wash the vegetable leaves. If it is wrongly used for soil treatment, it can be washed in the field. After the phytotoxicity of the vegetables, the water content of the cells can be increased by watering, thereby reducing the content of the drugs in the vegetable plants.
Neutralization treatment should first understand the physicochemical properties of the pesticide. If the pesticide is wrong, it can be combined with water spray and then neutralized according to the acidity and alkalinity of the pesticide. For example, after spraying the oxidized omethoate, it can be neutralized with a stone sulphur mixture, a Bordeaux solution or an aqueous lime solution.
Buffering treatment uses pesticide formulation techniques to buffer phytotoxicity. Spraying a specific drug to relieve the drug that causes the phytotoxicity of vegetables. For example, after sputum sulphate copper sulphate damage, the lime concentration of 5%~10% can be added to the hydrolytic toxic treatment to remedy the opposite characteristics of some pesticides. For example, administration of paclobutrazol in excess of phytotoxicity can be treated with gibberellin because the former is a plant growth retardant and the latter is a plant growth promoter.
According to the law of vegetable growth, it is possible to enhance the growth of vegetables by increasing topdressing. Improve resistance to phytotoxicity. For example, when applying fertilizer with water and spraying fertilizer, it can improve the resistance of vegetables.
