Preparation method of composition used for preventing and controlling vegetable leaf miner

Abstract

The invention discloses a preparation method of a composition used for preventing and controlling vegetable leaf miner. The preparation method comprises following steps: A, raw materials, including 50% dimethoate emulsifiable concentrate, 25% carbendazim, cinnamyl aldehyde, saikoside, matrine, urotropine, trifloxysulfuron sodium and coumaphos are prepared; B, 50% dimethoate emulsifiable concentrate and 25% carbendazim are diluted with water for 50 times; urotropine, trifloxysulfuron sodium and coumaphos are added so as to obtain a mixture; and the mixture is stirred uniformly; C, cinnamyl aldehyde, saikoside, and matrine are diluted with water for 10 times, and are stirred uniformly so as to obtain a mixed material; and D, the mixture obtained in step B and the mixed material obtained in step C are mixed together, and are sterilized so as to obtain the composition used for preventing and controlling vegetable leaf miner. The preparation method is simple; product composition is simple; the composition is convenient for application; and preventing and controlling effect on vegetable leaf miner is excellent. According to the preparation method, traditional Chinese medicine intermediates and pesticide intermediates are added on the basis of traditional pesticides, and the novel composition specially used for preventing and controlling vegetable leaf miner is obtained via mixing; and preventing and controlling effect is excellent, and is 15 to 18% higher than that of traditional pesticides.

Description

[0001] technical field [0002] The invention belongs to the technical field of vegetable pest control, and in particular relates to a preparation method of a vegetable leaf miner control composition. [0003] Background technique [0004] Leaf miner body length 4 ~ 6 mm, taupe. The male fly has hairs under the front edge, the legs and tibias are grayish yellow, the tarsus is black, and the hind tibia has 3 bristles. Eggs are white, oval, 0.9 mm x 0.3 mm in size, and mature larvae are about 7.5 mm long, wrinkled and black-yellow. Pupa, about 5 mm long, oval in shape, light yellowish brown at first, then reddish brown, and dark brown before eclosion. 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 t...

Problems solved by technology

In the prior art, as long as dimethoate or dichlorvos are used as medicines for preventing and treating leafminers, the perennial use has caused the leafminers to develop drug resistance, the control effect is not good, and the damage to vegetables is seriously reduced. In order to solve this technical problem, it is necessary to develop A method for preparing a vegetable leafminer control composition with simple preparation method, simple proportioning of the prepared product, convenient use and good effect of preventing and controlling leafminer
