The role of prochloraz
Prochloraz product introduction Prochloraz is an efficient, broad-spectrum and low-toxic fungicide with many functions such as prevention, protection and treatment. The preparation consists of 25% emulsifiable concentrate, 45% microemulsion, 45% emulsion in water, 50% wettable powder, 50% suspending agent, 0.05% aqua, 30% microcapsule suspending agent, 1.5% seed coating agent, etc. It is a broad-spectrum bactericide. The effect of compound prochloraz alone is not good. After prochloraz is compounded with other fungicides and pesticides, it can not only obviously enhance the action effect, but also expand the scope of control objects. Conductive prochloraz itself has no systemic effect, but it has certain conductive effect. After application, it can quickly spread to all parts of the plant, which plays a comprehensive role in protecting crops and has a good therapeutic effect on the diseased parts. The resistance is relatively low. Compared with similar imidazoles such as thiabendazole, imazalil and triflumizole, the resistance of prochloraz is relatively low. In addition, the resistance of prochloraz is lower than other drugs such as triadimefon and chlorothalonil. Pay attention to dosage and use time. When using prochloraz, we must pay attention to the dosage and time of use, otherwise it will easily cause phytotoxicity, especially emulsifiable concentrate. Do not exceed the normal dosage, and be sure to avoid the high temperature period at noon (emulsifiable concentrate). Watch out for poison. The drug is toxic to fish and moderately irritating to rabbit skin and eyes. Never clean the spraying tools by the river after spraying, and never throw medicine bottles and residual liquid medicine into fish ponds, rivers or ditches. The combination of prochloraz and other pesticides can greatly reduce drug resistance. If prochloraz forms a complex with divalent manganese, it can not only maintain the original activity of pesticides, but also increase the drug resistance of crops. In addition, it is suggested that prochloraz should not be mixed with the same pesticide all the time. Alternating use with other pesticides can reduce drug resistance. Taking rice as an example, there is a potential risk of resistance of rice bakanae to prochloraz. It is suggested that this drug should be used alternately with other drugs with different mechanisms, such as trichloroisocyanuric acid, in order to delay or avoid the emergence of resistance. Precautions when mixing prochloraz can be mixed with a variety of pesticides, and the effect is very good, but it is not suitable for mixing with strong acid and strong alkali pesticides, which is prone to phytotoxicity. In case of accidental phytotoxicity, it is suggested to spray 14- hydroxybrassinolide, 8~ 10ml water per barrel and 25g cytokinin on the leaves. You can also spray 3 ml of 1.8% sodium nitrophenolate solution and 20 g of chitin into each barrel of water. Or use 0. 126% red, indane and Brassica. Storage taboo
