Sophocarpidine compound prevention and treatment agent for preventing and treating trialeurodes vaporariorum

Abstract

The invention discloses a sophocarpidine compound prevention and treatment agent for preventing and treating trialeurodes vaporariorum. The sophocarpidine compound prevention and treatment agent is prepared from the following components by weight percent: 5-10% of mint oil, 2-5% of sophocarpidine and the balance of a bacillus thuringiensis culture solution, wherein the bacillus thuringiensis culture solution is prepared by inoculating bacillus thuringiensis into a spore production culture medium to enrich and carry out spore production culture and the spore production culture medium is prepared from the following components by weight percent: 4% of brown sugar, 1% of corn flour, 0.05% of zinc sulfate, 0.05% of magnesium sulfate, 0.01% of manganese sulfate, 0.003% of ferrous sulfate, 0.3% of sodium chloride, 0.01% of calcium carbonate and the balance of water which is added until the total volume is 100%; bacillus thuringiensis is inoculated according to 0.1% of the spore production culture medium; by actual large-field planting, the effect of effectively inhibiting spawns and adults of the trialeurodes vaporariorum can be realized; and crops can be induced to produce protectin, the robust growth of the crops is facilitated and the quality of the crops is improved.

Description

technical field [0001] The invention relates to a matrine combination control agent for controlling whitefly, belonging to the technical field of plant pest control. Background technique [0002] Whitefly belongs to the family Whitefly of the order Homoptera, is a worldwide pest, and is the main pest of crops grown in vegetable fields, greenhouses, and greenhouses. Its host has a wide range of nitrogen fertilizers, and it attacks cucumbers, melons, tomatoes, peppers, wax gourds, beans, cabbage, and celery. It can also harm 653 species of plants in 112 families such as flowers and fruit trees. Adults and nymphs suck plant juice, and the damaged leaves chlorosis, Turn yellow, even the whole plant dies, in addition, due to its strong fecundity and fast reproduction speed, the population is huge. Clustering hazards, and secreting a large amount of honey juice, it is easy to cause a large number of coal stains, causing a large amount of black coal stains on vegetables and fruits...

AI Technical Summary

Problems solved by technology

Clustering hazards, and secreting a large amount of honey juice, it is easy to cause a large number of coal stains, causing a large amount of black coal stains on vegetables and fruits, and losing their commercial value. At present, the common control methods for whiteflies include chemical pesticide control, common The chemical pesticides used include bifenthrin, imidacloprid, acetamiprid, kungfuthrin, cyanide zinc chloride EC, and chrysanthemum EC. For physical control, sticky shellac is used for physical control. In actual use, due to the flight migration and feeding habits of whitefly, when spraying pesticides, whitefly will fly away from the infected leaves and pass through rain or water. The loss of dew will reduce the control effect on whitefly. The way of yellow board capture, due to the rapid reproduction of whitefly and the large number of colonies, the control effect is poor. Facing the food safety requirements of the market, it is gradually becoming pollution-free and ecological. With the development of organic planting, the requirements for no pesticide residues and internal quality are getting higher and higher. It is really necessary to explore the best way to control whitefly and find the control of plant sources that can improve the self-protection of plants and block their flight migration. method, and overcome the problems of pesticide residues and resistance caused by spraying chemical pesticides during control
