Chlorothalonil is a high-efficiency, low-toxicity and broad-spectrum fungicide, which has a preventive effect on a variety of crop fungal diseases, with stable efficacy and long residual effect. It can be used for wheat, rice, vegetables, fruit trees, peanuts, tea and other crops, and can prevent wheat scab, tomato early blight, late blight, leaf mold, spot blight, melon downy mildew, anthracnose, etc., and can also be used for peach brown rot, scab, tea anthracnose, tea cake disease, net cake disease, peanut leaf spot, rubber canker, cabbage downy mildew, black spot, grape anthracnose, eggplant gray mold, orange scab.Specific usage of chlorothalonilThere are still many practical ways to use chlorothalonil, spraying, powder spraying and smoking, etc., the effect is good, but the actual situation is different. The following is a three-point introduction to the matters that should be paid attention to in the use of chlorothalonil:
1) chlorothalonil is a protective fungicideThe best time to use the crop is pre-disease prevention or early disease, taking 75% WP as an exampleGenerally, it is diluted 600-800 times for sprayingIt is recommended to repeat the prevention and control in 7-10 days;It can also be mixed with other fungicide products, such as methalin, methafin, forma, enoylmorpholine, mancozeb, tebuconazole, cyanide, etc., or use their mixture products to improve the control effect. However, it should not be mixed with alkaline pesticides such as stone sulfur mixture, mixed with thiophosphine, which is easy to cause pesticide damage on peach trees, and mixed with mites and tricyclic tin, etc., and is prone to pesticide damage on tea trees.
Crops such as pear trees and persimmons are sensitive to chlorothalonil and are harmful to roses and other crops, must not be used;The concentration should not be too high when usingHigh concentrations are easy to cause pesticide damage on apples, peaches, plums and some grape varieties；The young fruit stage within 20 days after the apple falls can not be medicated, which will cause rust spots on the fruit.
3) chlorothalonilIt is highly toxic to bees, fish and crustaceansWhen using, you must pay attention to work safety and environmental safety.
