How to use the manufacturer's fungicides and insecticides
Generally speaking, the spraying time of pesticide manufacturers too late or too early will affect the control effect. Spraying too early not only causes waste, but also reduces the control effect. If the spraying time is too late, a large number of pathogenic bacteria have invaded the host or caused harm. At this time, even spraying the systemic therapeutic agent has achieved twice the result with half the effort. Agricultural fungicides are Z-based and can be used directly in farmland to eliminate bacteria in farmland; algaecide, used in sewage treatment, can effectively purify sewage. Whether it is animals or humans, there must be a variety of microorganisms. Some of the microorganisms will cause harm to the body, so they need to be treated. At this time, it is necessary to use microbial fungicides to deal with harmful microorganisms on the body.
Reasonably configure the concentration of pesticide manufacturers, whether it is a water agent or a wettable powder drug, it needs to be diluted with water before spraying. Different concentrations have requirements, so it is necessary to strictly follow the instructions for proportioning, and a reasonable configuration concentration is more conducive to its effectiveness. If the ratio is random, too high concentration will cause phytotoxicity to crops; too low concentration will not meet the control requirements.
Insecticide manufacturers should use an appropriate amount of medication. Too much application will increase costs and cause phytotoxicity, and too little will not achieve the control effect. Therefore, increase or decrease it according to the specific situation. The number of doses depends on the residual period of the drug and the weather conditions. Generally, it is sprayed once every 10-15 days. If it rains after spraying, it needs to be sprayed again. The method of improving the quality of medicine is to spray the spray point evenly and finely, and spray the stem and leaves of the plant.
