Spraying large quantities of water to wash the medicine Because of spraying a certain kind of pesticide to cause phytotoxicity to the plants and leaves, it is possible to spray large water 2 to 3 times repeatedly to try to flush out the medicine on the surface of the plant. It is also possible to add 0.2% alkali or 0.5% lime water to the sprayed clean water. Since most pesticides are now susceptible to decomposition and loss due to alkaline substances, decomposition of the chemicals can be accelerated. Spraying water at the same time increases the moisture in the crop cells, dilutes the concentration of the liquid in the crop, and also reduces crop phytotoxicity.
Spraying drugs that ease drug harm The drugs that cause crop damage can be sprayed with targeted drugs that can ease the drug, which can greatly reduce the damage caused by the injury. For example, omethoate, parathion, and other pesticides can cause phytotoxicity to crops and can be mitigated by spraying 0.2% borax solution on damaged crops; rapeseed, peanut seedlings are inhibited by paclobutrazol, and growth stagnation can be promptly applied. The “90%†solution of % can quickly restore the normal growth of crops; crop phytotoxicity caused by copper sulphate and Bordeaux mixture can be sprayed with 0.5% lime water to ease the phytotoxicity.
Irrigation and drainage of water to reduce drug residues caused by some herbicides caused by phytotoxicity, appropriate drainage, can reduce drug residues. For example, the rice dwarf disease caused by Trichosanthes can be drained immediately after the initial stage, and then using gap irrigation to reduce residual pesticide residues, thereby reducing the extent of injury.
The immediate application of available nitrogen fertilizers may cause damage to foliar lesions, leaf scorch, or plant yellowing, and may apply 5 to 12 kg of urea per 667 square meters (1 mu), depending on soil fertility and crop growth. Appropriate application of phosphorus and potassium fertilizers, supplementation of plant nutrition, combined with cultivating loose soil, promote root development, enhance plant resistance to drugs, the effects of seed damage on seedlings, seedlings is very obvious.
When the phytotoxicity part is removed from the fruit tree by using methods such as perfusion, injection, and bandaging to overdosage and excessive concentration, the severed damaged branches should be quickly cut off to avoid further conduction and infiltration of the medicinal substances, and timely irrigation should be performed to prevent Drug damage continues to expand.
