Preparation method of pesticide for controlling leaf miner

Abstract

The invention discloses a preparation method of a pesticide for controlling leaf miner, which comprises the following steps: A. preparing 40% dimethoate missible oil, 40% diazinon missible oil, clove oil, anemone saponin, arteannuin, abamectin, sodium humate and coumaphos; B. diluting the 40% dimethoate missible oil and 40% diazinon missible oil to a 50-time solution with water, adding the abamectin, sodium humate and coumaphos, and stirring uniformly; C. diluting the clove oil, anemone saponin and arteannuin 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 pesticide for controlling 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 disease and insect pest control, and in particular relates to a preparation method of a medicine for preventing and controlling leaf miners. [0003] Background technique [0004] Leaf miners are 4 to 6 mm long and gray-brown. The male flies have hair under the front edge, the legs and tibia are gray-yellow, the tarsus is black, and the hind tibia is 3 bristles. Eggs are white, oval, 0.9 mm × 0.3 mm in size, and mature larvae are about 7.5 mm long, wrinkled, and dark yellow. The pupa, about 5 mm long, is oval in shape, initially light yellow-brown, then reddish-brown, and dark brown before eclosion. Leafminer is one of the main pests and diseases of vegetables. As larvae, it sneaks under the epidermis of the host leaf, zigzags through, and feeds on green tissues, resulting in irregular gray-white linear tunnels. When the damage is serious, almost all the leaf tissue is damaged, and ...

Problems solved by technology

In the prior art, as long as dimethoate or dichlorvos are used as medicines for preventing and controlling 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 drug for preventing and controlling leaf miners with simple preparation method, simple proportioning of the prepared product, convenient use and good effect in preventing and controlling leaf miners
