Application method of prevention drug for leaf miner

Abstract

The invention discloses an application method of a prevention drug for leaf miner. The application method comprises the following steps: A. stock solution is taken for future use: the stock solution consists of 40% dimethoate missible oil, 40% diazinon missible oil, clove oil, pycnonotus sinensis saponin, artemisinin, abamectin, sodium humate and coumaphos; B. the spraying period is 3-5 times and the spraying is implemented every 3 days: at the beginning of paroxysm, as eggs are mainly laid on the back surfaces of leaves, the stock solution is diluted to 1000 times of volume for spraying; C. in the imago phase, the stock solution is diluted to 1300 times of volume for spraying; D. after the temperature is higher than 26 DEG C, the spraying time and the spraying period are required to be increased; the spraying is implemented every 4 days, and is continuously implemented for 4-5 times. The application method is simple to apply, simple in preparation of used products, convenient to use, and good in leaf miner preventing effect and is 115-118% of the prevention effect of the traditional pesticide.

Description

[0001] technical field [0002] The invention belongs to the technical field of vegetable disease and insect pest control, in particular to a method for using a control medicine for leafminer. [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 the leaves are covered with wormholes,...

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 of using a drug for preventing and controlling leaf miners with simple use method, simple product ratio, convenient use, and good effect in preventing and controlling leaf miners
