Nowadays, many farmers' friends always rely on experience to form their own conceptual medications for specific diseases of a certain crop. They are also a headache, a painful foot, and often use the same kind of pesticide disinfectant approved by themselves to control crop diseases. In this way, the beginning may be better, but the problem of pesticide bactericide resistance will occur over time, and the effect will be greatly reduced. If the tomato develops a late blight, it can be used with chlorpyrifos or metalaxyl. If an early blight occurs, it can be sprayed with manganese sulphate or anti-drug. When a bacterial disease occurs, copper is sprayed. The result is that the disease is cured. A kind of disease, the calamus scooped up again, and the cure was not cured. The reason is that the single drug is not conducive to the comprehensive control of multiple diseases. For example, if there is powdery mildew in cucumber, we can use 800-1000 times diluted with ethyl acesulfame foliar spray; it can also be diluted with 1000-1500 times with fumfen ester foliar spray; nitrile is also good for powdery mildew . There are many choices in the selection. It can be applied in turn or in combination. The use of scientific and rational pesticides can expand the scope of use or treat several harmful organisms, and even increase the efficacy and reduce the side effects of pesticides such as drug resistance and phytotoxicity, which is efficient, labor-saving and time-saving. Such as Wang copper can be mixed with many pesticide fungicides, pesticides . The mixture is sprayed with 30% suspension 600 times solution and 70% thiophanate 800 times solution to control bacterial leaf blight, anthracnose, bacterial angular spot disease and other diseases of vegetable brown spot. 5M Measuring Tape,Automatic Tape Measure,Tape Measure Scale,Measuring Tape 5 Meter SHANGQIU CHAOYUE MEASURING TOOLS CO., LTD , https://www.calibrateds.com
