Pesticide vegetable pesticide application "two choices two attention"

Spraying vegetables is very useful because greenhouse vegetables cause pests and diseases due to excessive humidity. Not only the application of the drug control, but also the humidity in the shed. Therefore, the prevention and control of greenhouse vegetable pests and diseases should promote the application of powder spraying. China Pesticide Network Xiaobian reminds everyone to pay attention to the following "two choices and two attentions":
First and second choices 1. Select appropriate dust to control cucumber downy mildew, tomato late blight, use 10% anti-mildew or 5% chlorothalonil dust; control cucumber anthracnose, black heart disease, choose 5% Chlorothalonil or 12% of Cokeling dust; control of cucumber bacterial angular leaf spot, use 10% of B drop dust; control vegetable gray mold, leaf mold, early blight and late blight, use beneficial dust Agent.
2, choose the appropriate duster should use the domestic harvest 5 or 10 type hand powder sprayer. Before spraying the pesticide , close the shed, then measure it by 1 kg per mu, and put the pesticide into the sprayer medicine box. The amount of powder discharged is adjusted to about 200 grams per minute.
Second, two attention 1, pay attention to the spraying time on sunny days should be applied in the morning or evening, cloudy and rainy days can spray. Applying the best after closing the shed in the evening. In the sunny morning to afternoon, the sunlight is strong and the dust control effect is low.
2, pay attention to spraying pesticide manufacturers to remind farmers <br> method: spraying against vegetables, whether uniform or not, the effect is very poor when dusting. Only a uniform air-to-air powdering effect is good. If the powder is not evenly distributed, some of the powders will not disperse well and the control effect will be reduced.
