The diseases that occur during the storage of S. oleifera can be roughly classified into two types: physiological injury and pathogen infestation. The former is mainly due to uncomfortable factors such as gas composition during storage, and the latter is caused by the intrusion of microorganisms. The physiological damage of garlic moss occurs in the physiological and biochemical processes, metabolic disorders, disease resistance greatly reduced, pathogenic microorganisms can easily invade. The propagation and growth of microorganisms will destroy the gas composition and cause physiological damage. The two are related to each other and affect each other. Moldy rot in the storage of S. oleifera occurs during late storage. This is because as the storage period prolongs, the S. oleifera gradually ages and the resistance to disease weakens. Botrytis cinerea grows and reproduces. change. If storage management measures are improper, it will accelerate the aging process, produce physiological damage, and result in increased rot and mildew in the middle and later stages of storage. Controlling the storage and decay of garlic in the middle and late stages of storage should begin with the following aspects. 1, pick a good warehouse disinfection. Thoroughly sterilize warehouses before putting garlic into the warehouse to remove pathogens that were retained in previous years. 2, strictly control the quality of storage, as much as possible to reduce pathogenic bacteria and garlic storage. Before the acquisition of garlic, it is necessary to investigate the origin of garlic and ensure the storage of high-quality garlic. 3, garlic moss anti-fresh smoke agent fumigation. In order to study the characteristics of the mildew-inducing pathogens caused by garlic sprouts in the middle and late stages of storage, researchers have developed a good effect of the garlic moss mildew preservation of the smoke, it is recommended that the cold storage of garlic moss on the basis of strengthening the comprehensive storage management, the application of anti-mildew fresh smoke agent fumigation. 4. Strengthen the comprehensive management of storage period and maintain the best storage conditions. Only in this way can we delay the aging of the garlic, reduce various physiological damages (such as CO2 poisoning), keep the body of the garlic moss healthy, and resist the invasion of various germs. In short, the prevention and treatment of mildew in the late period of storage of garlic moss should focus on the removal of pathogens, to ensure the quality of storage of garlic, maintain the best storage conditions, anti-mildew and fresh smoke agent fumigation and other considerations. Measures should not be single. Comprehensive prevention and control are the best solutions. China Agricultural Network Editor
