How to use low toxic fungicides? Please introduce the following methods for the use of several low-toxic fungicides: antimycin 120 (agricultural antibiotic 120, 120 agricultural antibiotics) is suitable for the control of powdery mildew, anthracnose and Fusarium wilt. To control melons, eggplant Fusarium wilt and other soil-borne diseases, 130 to 200 times of 2% water agent can be used to irrigate roots, 500 ml each time, once every 5 days. Metalaxyl can be used to control downy mildew of cucumber and cabbage, blight of cucumber and green pepper, late blight of potato and so on. Generally use 25% wettable powder 600 to 800 times liquid spray at the initial stage of the disease. For soil-borne diseases, soil can be treated with 400 to 500 grams of 25% wettable powder mixed with water per mu. Prike can control leaf diseases caused by Pythium, Phytophthora and downy mildew. Watering with 400 to 600 times 72.2% Pulick water-soluble liquid can control vegetable blight, sudden fall and blight at seedling stage. The cucumber downy mildew can be prevented by spraying the water-soluble liquid at the initial stage of the disease with a water-soluble liquid of 6 to 1000 times. The mixture of this drug and non-alkaline fungicide can improve the control effect. Antivirus alum can be used to control tomato early blight, late blight, rot, cucumber downy mildew, eggplant cotton blight, potato early blight and late blight and so on. It is generally sprayed with 64% wettable powder 400 times liquid at the initial stage of the disease. Pythium (Sukeling) has a special effect on Botrytis cinerea and Sclerotinia sclerotiorum of melons, vegetables and grapes, generally using 50% wettable powder 600 to 800 times liquid spray or 30% granule fumigation. Aluminum ethyl phosphate (also known as triethyl aluminum phosphate and alaxyl) has a significant control effect on downy mildew and blight of many kinds of crops and can be valid for more than 20 days. Generally use 40% ethyl phosphate aluminum 250 to 300 times liquid spray. Propofol mainly plays a preventive role, such as early blight of tomato, gray mold of cucumber and pea and so on.
