How to use fungicide better 1
Fungicide A class of pesticides, generally fungicides, used to control plant diseases caused by various pathogenic microorganisms. The use of fungicides is a cost-effective way to control plant diseases.
Due to the application of fungicide technology is more complex, so the speed of development is not as fast as insecticides, but the effect of fungicide on agricultural production protection has been more and more recognized by farmers, with the modernization of agriculture, the development of fungicide will be accelerated. So how to use fungicide is better, here is a look at the use of fungicide have what skills.
How to use fungicide better reasonable allocation concentration:
When using fungicides (including water and wettable powder) spray, it is necessary to mix or dilute the agent with water to the appropriate concentration. The concentration of different fungicides has its special requirements, the configuration of the concentration must be in strict accordance with the operation instructions, can not be arbitrarily increased or reduced. If the concentration is too high, it is easy to cause drug harm, while if the concentration is too low, it cannot achieve the effect of drug prevention and control disease.
How to use fungicide better selection of spraying time:
Generally speaking, spraying fungicide too late or too early will affect the control effect. Spraying too early not only causes waste, but also reduces the control effect. And spray time is too late because a large number of agents have invaded the host or caused harm, then even if the injection of internal absorption therapy, but also because of the result of late. Therefore, the use of fungicides should be based on the occurrence of different crop diseases and the specific situation of disease prediction and timely use of drugs. Usually fungicide medication time should be mastered in the onset of disease (protective medication) or early onset of disease (prevention of disease) is better.
