In the spring, it is the main period for controlling grape anthracnose, white rot and downy mildew. To achieve this, effective prevention and control should be implemented as follows. 1. Anthracnose: (1) Completely remove sick ears, diseased vines, and diseased leaves to reduce the source of bacteria. (2) Strengthen cultivation management, pruning, vines, and topping in a timely manner so as to ventilate the racks. Increase phosphorus and potassium fertilizers to control the amount of nitrogen fertilizer. (3) In the period of sprouting into a pile of balls, a 100-fold dilution of the special bacteria is sprayed. (4) In late May, 80% of anthraquinone may be sprayed with 700-800 times solution, or mancozebite may be 800 times solution. 2. White rot: (1) Complete removal of diseased vines, diseased ears, and diseased leaves. (2) timely pruning, timely weeding, pay attention to drainage. For leggy plants, nitrogen fertilizer is strictly prohibited before flowering. (3) After the grapes are unearthed, spray 5 bumeme lime sulfur or chlorothalonil 100 times. The young fruit period begins (in early June) and sprays every 15 days until harvesting. 3. Downy mildew: (1) Remove fallen leaves, buried diseased branches or burned. (2) timely picking, pruning, drainage and weeding, increasing phosphorus and potassium fertilizers. (3) Spraying should begin at the beginning of the disease. Before the onset of illness, spraying with Bordeaux has the best effect. If downy mildew occurs, it should be sprayed with 25% metalaxyl 700 times to prevent and treat it.
