NOVELTY - A grapes coal spot disease controlling method involves processing soil ecologically by applying 400 ml fertilizer to trees, pouring water sufficiently by drip irrigation, and watering roots, controlling coal spot disease in grapes agriculturally, physically, biologically and chemically. The coal spot disease in grapes agriculturally is controlled by selecting disease-resistant grape variety, strengthening cultivation management, paying attention for drainage, removing weeds in garden, yellow grape leaves and diseased grape leaves and facilitating air and light to reduce humidity.    USE - Method for controlling coal spot disease in grapes.    ADVANTAGE - The method enables controlling coal spot disease in grapes in environmentally-friendly and effective manner and at earlier stage with low toxicity and good therapeutic effect, killing bacteria rapidly, preventing damage to grape quality, and applying pollution-free pesticides.    DETAILED DESCRIPTION - A grapes coal spot disease controlling method involves processing soil ecologically by applying 400 ml fertilizer to trees, pouring water sufficiently by drip irrigation, and watering roots, controlling coal spot disease in grapes agriculturally, controlling coal spot disease in grapes physically, controlling coal spot disease in grapes biologically, and controlling coal spot disease in grapes chemically. The coal spot disease in grapes agriculturally is controlled by selecting disease-resistant grape variety, strengthening cultivation management, paying attention for drainage for long-term, removing weeds in garden, yellow grape leaves and diseased grape leaves and facilitating air and light to reduce humidity. The coal spot disease in grapes is controlled biologically by removing insects in grape leaves and nonhost plants, blocking bacteria propagation, reducing coal spot disease in grapes effectively, applying compost and organic fertilizer, and applying 0.3% polyoxin for 300 times. The coal spot disease in grapes is controlled physically by checking vineyard, removing fallen grape leaves and diseased branches, cleaning orchard in autumn completely, burning deep buried leaves, and reducing overwintering bacteria source. The coal spot disease in grapes is controlled chemically by spraying 722 g/l propamocarb hydrochloride agent for 600 times, 430 g/l suspending agent for 2500 times, Bordeaux fertilizer to leaves, 58% metalaxyl-manganese zinc wettable powder for 500 times, 80% zineb wettable powder for 600 times, and medicinal composition, where the medicinal composition comprises 1-5 wt.% resmethrin, 3-7 wt.% dodecanethiol, 2-6 wt.% vinegar, 2-6 wt.% ivermectin, 7-11 wt.% glucose and 1-3 wt.% sulfur.
