How to better use fungicides
Fungicides are a class of pesticides used to control plant diseases caused by various pathogenic microorganisms, generally refer to fungicides. The use of fungicides is a cost-effective way to control plant diseases.
Because the application technology of fungicides is more complicated, the development speed is not as fast as that of pesticides, but the effect of fungicides on agricultural yield increase and protection has been more and more recognized by farmers. With the modernization of agriculture, the development of fungicides will definitely accelerate. . So how to use fungicides is better, let's take a look at the skills of using fungicides.
How to use bactericides and reasonable configuration concentrations:
When spraying with fungicides (including water and wettable powder), it is necessary to formulate or dilute the agent with water to an appropriate concentration. Different fungicides have special requirements for their use concentration. When configuring the concentration, it must be operated in strict accordance with the instructions for use, and cannot be increased or reduced at will. If the concentration is too high, it is very easy to cause phytotoxicity, and if the concentration is too low, the effect of drug use to prevent and control diseases cannot be achieved.
How to use the fungicide, the best choice for the spraying time:
In general, spraying fungicides too late or too early will affect the control effect. Premature spraying will not only cause waste, but also reduce the control effect. And the spraying time is too late because a large number of pathogens have invaded the host or caused harm. At this time, even if the systemic therapeutic agent is sprayed, it will be less effective because of the late-breaking repair. Therefore, the use of fungicides should be based on the occurrence law and forecast of different crop diseases, as well as the specific conditions of the disease occurrence. Usually, the application time of fungicides should be mastered before the onset (protective medication) or at the early stage of the onset (preventing problems).
How to use fungicides better to master the frequency of medication:
The number of sprays of fungicides is mainly determined according to the length of the residual period of the pesticide and the weather conditions. Generally, spray once every 10 to 15 days, and spray 2 to 3 times in total. In special circumstances, such as rain after spraying, it should be re-sprayed in time.
How to use fungicides better to improve the quality of medication:
The spraying quality of fungicides includes the quantity and quality of spraying. The amount of medication should be appropriate. Excessive medication on the one hand will increase the cost, and on the other hand, it will easily cause phytotoxicity. And too little medication can not achieve the purpose of medication. The quality of the medicine should be paid attention to. When spraying, the mist should be fine and evenly sprayed.
