Abstract

The invention discloses a preparation method of a compound pesticide for controlling vegetable leaf miner, which comprises the following steps: A. preparing 40% diazinon missible oil, 50% dichlorvos missible oil, tea polyphenol, radix astragali polysaccharide, phillyrin, tebuthiuron, nitenpyram and coumaphos; B. diluting the 40% diazinon missible oil and 50% dichlorvos missible oil to a 50-time solution with water, adding the c tebuthiuron, tebuthiuron and coumaphos, and stirring uniformly; C. diluting the tea polyphenol, radix astragali, polysaccharide and phillyrin to a 10-time solution with water, and stirring uniformly; and D. mixing the substances obtained in the step B and step C, and sterilizing to obtain the compound pesticide for controlling vegetable leaf miner. The preparation method is simple; and the prepared product is simple in proportioning and convenient to use, and has favorable control effect on leaf miner. The traditional Chinese medicine intermediates and pesticide intermediates are added on the basis of the traditional pesticide and mixed to obtain the new pesticide for leaf miner with favorable control effect, and the control effect is enhanced by 15-18% as compared with the traditional pesticide.

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 compound medicine for preventing and controlling vegetable leafminer. [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 cover...
