Improve the spraying method can improve the efficacy
In recent years, vegetable pests and diseases in greenhouses have become more and more serious, and vegetable farmers have been increasingly spraying. However, many vegetable farmers have shown that the use of pesticides has become less and less effective. Recently, during the interview, the reporter deliberately took a look at the way the vegetable farmers sprayed and found that the farmers were very irregular when spraying, which affected the efficacy of the drug.
1. Heavy fog spray. The reporter observed in many sheds that the sprayer's agent was a large drop of mist. This spraying method would make the spray uneven, especially affecting the control effect of the contact agent. Large droplets of spray can also cause the loss of liquid chemicals, and the waste is even more serious when the plants are low. Therefore, a sprayer with good atomization performance should be used, and spray holes should be used to spray evenly.
2. When spraying, the zigzag swing spray in front of the body. Spraying medicine directly in front of the body, often before the end of spraying the drug, the vegetable farmers have to continue to work in the sprayed drug environment, likely to cause pesticide poisoning. In addition, when the closed herbicide is sprayed, it is easy to spray unevenly, and after the human stepping on it, the drug film is broken and the control effect is reduced. Should change the front of the hand sprayer "zi" swing to the lateral "zi" swing.
3. Do not distinguish between sprayer types that are direct "target" crops. Different sprayers should be different when spraying and cannot be in one mode. In general, manual sprayers can be sprayed with direct "targets". In order to give full play to its features of good atomization and high work efficiency, the motorized sprayer should be sprayed at a height of 20 cm above the crop.
4. The sprayed liquid dripped from the leaves. The reporter observed some newly sprayed leaves and found that many liquids dripped from the leaves and some dripped directly on the ground. As a result, the effective dose of the liquid on the leaves was reduced. It was not only difficult to exert efficacy, but also caused a lot of pesticide waste. . Therefore, the spraying should be uniform during the operation, and the spraying residence time should be reduced as much as possible to reduce the dropping of the liquid medicine from the leaves up and down and improve the efficacy.
