Phytomyza atricornis killing composition capable of avoiding lawn damage

Abstract

The invention discloses a phytomyza atricornis killing composition capable of avoiding lawn damage. The phytomyza atricornis killing composition is prepared form, by weight, 3-6 parts of metsulfuron-methyl, 3-6 parts of 2,4-dichlorphenoxyacetic acid, 2-5 parts of tea polyphenol, 1-3 parts of astragalus polysaccharide, 2-4 parts of 70% sodium salt raw powder, 2-5 parts of tebuthiuron, 1-3 parts of nitenpyram and 3-6 parts of dinitraniline. The phytomyza atricornis killing composition is simple in matching, convenient to use and good in phytomyza atricornis prevention and control effect. According to the phytomyza atricornis killing composition, traditional Chinese medicine intermediates and agrochemical intermediates are added on the basis of traditional pesticide, the traditional Chinese medicine intermediates and agrochemical intermediates are mixed, then new drugs targeted to the phytomyza atricornis are obtained, the prevention and control effect is good, and the prevention and control effect is raised by 18%-20% compared with traditional pesticide.

Description

technical field [0001] The invention belongs to the technical field of vegetable pest control, and in particular relates to a leaf miner extermination composition for avoiding lawn damage. Background technique [0002] Leafminer is one of the main pests and diseases of vegetables. Its larvae sneak under the epidermis of the host leaves, zigzag through, and feed on green tissues, forming irregular gray-white linear tunnels. When the damage is serious, almost all the leaf tissue is damaged, and the leaves are covered with borers, especially the leaves at the base of the plant are the most severely damaged, and even withered and dead. The larvae can also feed on tender pods and flower stalks. Adults can also suck plant juice and make the sucked part into small white spots. Leafminers can harm turfgrass and cause damage to the lawns of sports venues or landscaping grasslands. In the prior art, the medicines for preventing leafminers only need dimethoate or dichlorvos, etc., ...

AI Technical Summary

Problems solved by technology

Leafminers can harm turfgrass and cause damage to the lawns of sports venues or landscaping grasslands. In the prior art, the medicines for preventing leafminers only need dimethoate or dichlorvos, etc., which have been used all year round, causing the leafminers to develop drug resistance. , the control effect is not good, and the vegetable production reduction damage is serious. In order to solve this technical problem, there is a need for a leafminer killing composition that is simple in proportion, easy to use, and has a good effect in preventing and controlling leafminers to avoid lawn damage.
