After entering the vigorous stage of flowering and cauliflower, it is easy for leaf curling and curling deformity, leaf green spots to lose green and yellowing, growth point atrophy, no new shoots, no new leaves, gradually decreasing flowering and peppercorns, and abnormal peppers. Increased, the plants gradually dwarf and so on, it is infected with virus disease. After the virus is infected with the virus, the yield and quality will be significantly reduced. Therefore, we must pay attention to the prevention and treatment of viral diseases during the process of flowering and picking peppers.
Refers to the day pepper virus disease transmitted by the tea plantarum virus, plants infected with the virus disease are generally tea seedlings damage, the prevention and treatment of finger pepper virus disease need to be controlled together with the tea, to have a good effect. Once the pepper is infected with the virus, it is difficult to cure. Therefore, prevention and control of the pepper virus disease should be the main prevention, do not wait for the emergence of viral symptoms before spraying control.
Therefore, during the growth and development of finger pepper, 600 times of mushroom proteoglycan, 800 times 1.8% of octamine acetate, 0.1% of zinc sulfate, 1500 times of 0.001% of natural brassica must be sprayed every 10 to 15 days. Vegetarian, 1500 times 5% avermectin mixture, continuous spraying 3 ~ 5 times, evenly spray all the leaves and pepper fruit. Mushroom proteoglycans, zinc sulphate, octanidyl acetate, and natural brassin are all antiviral agents that inhibit viral growth, impair viral activity, control virus reproduction, and kill viruses. Abamectin kills Deadly virus-producing tea leaves have cut off transmission of the virus. This will control the occurrence and harm of viral diseases.
