For the control of cucumber bacterial angular leaf spot and the eggplant verticillium wilt, we can choose to use fungicides, which can be used to cure bacterial and fungal diseases. China Pesticide Network Xiaobian specifically introduces you:
First, sclerotium net fungicide. It is a non-systemic broad-spectrum fungicide. The bactericide can effectively cure soybean sclerotinia, tomato and cucumber gray mold. Spraying is usually carried out using 40% of a wettable powder 500 times.
Second, the bactericidal fungicide. (DTM2) A combination of DT fungicide and ethylphosphorus aluminum, which can be used to cure downy mildew, anthracnose, and bacterial keratosis of vegetables.
Third, green milk copper fungicide. This agent can be used to cure fungal and bacterial diseases such as blight, downy mildew and anthrax. Usually use 12% green milk copper 600 to 1000 times spray or root irrigation.
Fourth, metalaxyl fungicide . It can be used to cure cucumber and green pepper diseases, cucumber and cabbage downy mildew, potato late blight and so on. Usually, 25 to 5% of the wettable powder is sprayed with 600 to 800 times at the beginning of the onset. For soil-borne diseases, we can use an average of 25 to 15 grams of WP 400 to 500 grams per acre to add water to treat the soil.
Fifth, Plex bactericide. This agent can cure leaf diseases caused by downy mildew, rot, and Phytophthora. Watering with 400 to 600 times 70.2% of the Plex water-soluble liquid can cure vegetable diseases and buckling disease and blight during seedlings.
Sixth, Tecdo fungicide. This fungicide can be conducted towards the top of the plant, but it can not be transmitted to the roots and is often used to keep the fruit fresh. For sclerotinia and spot blotch that can be used to cure celery on vegetables.
Seventh, anti-virus cockroach fungicide. This kind of pesticide can be used to cure many kinds of diseases such as cucumber downy mildew, early blight, late blight, and early blight of potato. Usually, when the disease is just occurring, a 64-fold wettable powder 400 times solution is used for spraying.
