NOVELTY - Preventing and treating almond gummosis comprises e.g. strengthening the management of water and fertilizer, enhancing growth vigor, and increasing disease resistance capacity by e.g. germinating during spring, filling humic acid organic fertilizer around the landfill, after 5-6 month, after rain, applying 55-75kg/acre fertilizer, mixing complex fertilizer, chicken manure and alfalfa silage powder according to mass ratio of 3:4:1, after 8 month, preparing liquid fertilizer, spraying 400-500 kg each for ten days, and timely draining during the rainy season.    USE - The method is useful for preventing and treating almond gummosis (claimed).    DETAILED DESCRIPTION - Preventing and treating almond gummosis comprises (i) strengthening the management of water and fertilizer, enhancing growth vigor, and increasing disease resistance capacity, specifically comprising (a) germinating during spring, filling humic acid organic fertilizer around the landfill, where the distance between trunk and humic acid organic fertilizer landfill is 10-20 cm, distance from the ground to annular region is 5-8 cm, (b) after 5-6 month, after rain, applying 55-75kg/acre fertilizer, mixing complex fertilizer, chicken manure and alfalfa silage powder according to mass ratio of 3:4:1, and (c) after 8 month, preparing liquid fertilizer comprising urea, phosphate and potassium fertilizer, plant ash, and water according to mass ratio of 1:3:3:100, per acre, spraying 400-500 kg each ten days, and timely draining during the rainy season, and (ii) preventing and treating specifically comprising (a) before forming tree body, germinating in the spring, spraying whole tree with 3-5 Baume degrees lime sulfur mixture or 45% crystal lime sulfur mixture 30 times, and (b) in early May o early June and early August to early September, before the peak of the disease, spraying 80% thiophanate liquid 1500 times or 50% carbendazim wettable powder 600-800 times, each 7-10 days, spraying one time, and interchangeably spraying 2-3 times.
