The existing control method of fruit tree white rot is mainly a chemical control technology and breeding of disease-resistant varieties, but chemical control has the problems of low control efficiency, difficult elimination of pathogen, difficult spraying in flowering phase, pesticide residue, environmental pollution and the like; the conventional breeding has the defects of difficult finding of effective resistant materials, very slow speed and the like, and the disease resistance problem is difficult to effectively solve.
The water-soluble fertilizer is a multi-element compound fertilizer capable of being completely dissolved in water, and compared with the traditional elemental fertilizer, common compound fertilizer and other fertilizers, the water-soluble fertilizer has the remarkable advantages of instant dissolution, high absorption rate, quick response, convenient application and the like, and is developed rapidly. The application of the water-soluble fertilizer to control diseases is an effective way for replacing chemical pesticides to prevent and control white rot, and along with social development, agricultural development increasingly demands pollution-free, efficient and low-labor-force products, so that the application mode of the novel water-soluble fertilizer is very necessary for preventing and controlling the white rot.
