Description
Technical Field
The invention belongs to the technical field of crop pest control, and particularly relates to a method for controlling cultivated southern blight of capsicum by using trichloroisocyanuric acid.
Background
Southern Pepper disease (Pepper Souhtern Blight) is a soil-borne disease caused by invasion of the base and root of the plant by sclerotinia rolfsii. The disease is particularly serious in high-temperature and high-humidity areas, and a large amount of pepper plants die, so that the disease becomes a main disease in pepper production in high-humidity and high-temperature areas in the south.
The sclerotium or hyphae of the sclerotium of the capsicum sclerotium overwinter in the soil, and the sclerotium or hyphae can burst into a disaster when meeting proper temperature and humidity, so the control difficulty of the capsicum sclerotium is large. At present, chemical agents are mainly used for prevention and treatment in production, but effective chemical agents are few, and five-way nitrobenzene and other agents are widely applied in production. However, in recent years, the Wulu nitrobenzene has poor effect of preventing and treating the southern blight, the price is high, the Wulu nitrobenzene has stable chemical properties, is not easy to volatilize, oxidize and decompose, and is not easy to be influenced by sunlight and acid and alkali, the Wulu nitrobenzene is listed as a list of 3 carcinogens by the world health organization in 2017 for 10 months, and the use of the Wulu nitrobenzene for preventing and treating the southern blight becomes a topic more sensitive than pesticide residues. Therefore, the control of the capsicum southern blight faces a great challenge.
Trichloroisocyanuric acid is a strong oxidant and a chlorinating agent, has the advantages of active chlorine content more than 3 times higher than that of bleaching powder, long effective chlorine release time in water, safety, no toxicity and the like, and is widely applied to the fields of industrial water, swimming pool water, hospitals, tableware and the like which are close to the daily life of people. After the trichloroisocyanuric acid is sprayed on target thalli, hypochlorous acid molecules with bactericidal capacity can be released, and the hypochlorous acid molecules have no charge and have strong capacity of diffusing and penetrating cell membranes. After entering host cells, the bacterial membrane permeability is changed, physiological and biochemical processes of a barycentric enzyme system are changed, DNA synthesis is influenced, and the like, so that germs die rapidly, and therefore, a safe and efficient sterilization mechanism of chloride ions can be utilized to kill sclerotium rolfsii in soil, and the purpose of preventing and treating diseases is achieved. The method is green, environment-friendly, efficient and simple to operate.

Considering that the incidence of the southern blight of the base is always serious, the incidence can be controlled within 5 percent so as to obtain high evaluation of the boss of the base.
