Grapes are prone to diseases such as downy mildew, black pox, anthracnose, and white rot from the fruit expansion stage to the mature stage. While doing a good job in the management of fertilizer and water in the field, we must do a good job of preventing and controlling various diseases in a timely manner. Downy mildew usually occurs most severely from June to July. 78% Kebo or 80% essential wettable powder 500-600 times or 27.12% copper noble suspension 500 times can be used for prevention before the onset or early stage of the occurrence, and can also prevent acne, anthracnose, white rot Occurred; in the middle and late stages of the disease, 60% of the WP wettable powder or 600% of the 72% cream urea manganese zinc wettable powder or 600% of the 72% Kelu wettable powder or 58% of the Redomier WP 500 times Wait for medicine to prevent and cure. After the occurrence of black pox and anthracnose disease, 66.75% of loose granules can be used for 800-1000 times of easy-to-hold moisture or 43% of Hercules suspending agent 3000-5000 times or 12.5% ​​of Lectobacter wettable powder 1500 times and other agents for prevention and control. The white rot disease begins in June, and the disease becomes more severe in case of heavy rain and typhoon in July-August, especially when the fruit enters the coloring period to the mature stage, the degree of susceptibility increases significantly. Powdery mildew high temperature and dry weather are conducive to the occurrence and prevalence of the disease, which is more serious from June to July, and the incidence is less in the later growth period. For the prevention and control of pharmacy, 43% of Hercules suspoemulsion can be selected from 3000 to 5000 times or 10% Shigao water dispersible granules to 1500 times. If the fruit color is gray to mature, if the weather is hot and humid, it will often lead to severe disease of the ears, especially in facility cultivation, we must focus on prevention. The medicament can be used alternately with 50% prothionine suspension agent 1000 times (preventive) or 40% Shijiale 800~1000 times or 50% Nongliling water dispersible granules 1000 times.
