What should be paid attention to when using fungicides? The following points should be paid attention to when using fungicides: first, the properties of fungicides should be made clear when choosing fungicides. There are two types of fungicides. One is protective agent, this kind of fungicide is to prevent plant disease, such as Bordeaux solution, mancozeb, carbendazim, etc.; the other is therapeutic agent, which is applied after the plant disease to kill or inhibit the pathogens invading the plant body. The therapeutic agent has a better effect in the early stage of the disease, such as Kangkuning, Baozhida and other compound fungicides. Fungicides should be sprayed before 9: 00 a.m. or after 4: 00 p.m. If sprayed in the hot sun, the chemical is easy to decompose and evaporate, which is not conducive to crop absorption. Third, the interval between the use of fungicides and spraying is 10 days. For agents with weak adhesion and poor internal absorption, it should be re-sprayed in case of rain within 3 hours after spraying. Fourth, fungicides should not be mixed with alkaline pesticides. Can not increase or reduce the use of fungicides at will, and should be used with. Fifth, fungicides are mostly powders, emulsions and gel suspensions, which must be diluted before application. When diluting, put the medicine first, then to the water, and then stir with a stick. When mixed with other pesticides, fungicides should be diluted first and then mixed with other pesticides.
