All crops found phytotoxicity and promptly remedy.
(1) Spraying the leaves in time with water spray; when spraying the wrong pesticide or releasing phytotoxicity, the leaves can be rapidly sprayed with plenty of fresh water when the early liquids have not been fully penetrated or absorbed, and washed repeatedly 3-4 times to try to put the surface of the plants. Liquid brush off.
(B) spray relieving agent. If the pesticide is caused by an acidic agent, an appropriate amount of quicklime may be added during the water flushing process; the harm caused by the alkaline agent may be added to the vinegar when the water is sprayed. If the silver pot type of copper sulfate caused by excessive damage, can be sprayed with 0.5% of lime hydrolysis and rescue; by the lime mixture after the harm, can be washed on the basis of the first, spray rice vinegar 400-500 times liquid can reduce the damage.
(3) Spraying medicines for relieving phytotoxicity, if paclobutrazol is sprayed in excess, the gibberellin can be added to mix with brassinolide spray for remission. The effect of auxogens and chlormequats on fruit can be relieved by spraying cytokinins. When herbicides appear on vegetable crops, they can be sprayed with Huimanfeng Active Liquid Fertilizer to ease the damage, and can also be sprayed with 800 times solution No.1 or 0.05% 920 solution, which can both detoxify and repair damaged cells. , At the same time can increase the application of urea and other available nitrogen fertilizer to raise seedlings;
(d) Irrigation and poisoning. In case of injury due to overdosing of soil, the fields should be washed in fields as soon as possible, so that a large amount of drugs will be discharged out of the field with water. On the one hand, the water content of crop cells will be increased, the metabolism will be promoted, the relative concentration of pesticides in the body will be reduced, and the degree of injury will be reduced. It reduces the concentration of pesticides in the soil and reduces the pesticide poisoning of crops.
(5) Timely increase of fertilization materials and the enhancement of fertilizer and water management. After the occurrence of crop injury, the growth will be hindered and the growth will be weakened. If NPK fertilizer or organic fertilizer is applied in time, the damaged plants can be restored to growth and their resistance to phytotoxicity can be improved. Spray 0.5% potassium dihydrogen phosphate and love more than 2 or 3 times to promote the rapid recovery of vegetable growth.
