Method for using calamus fly eradication composite

Abstract

The invention discloses a method for using a calamus fly eradication composite. The method comprises the steps that A, a stock solution is taken to be used, wherein the stock solution comprises metolachlor, cypermethrin, omethoate, baicalin, pirimicarb, stearic acid, ethirimol and coumaphos; B, at the early stage of fly attack, due to the fact that eggs are mainly laid on the back sides of leaves, the stock solution is diluted to 1000 times of the volume to be sprayed, wherein the stock solution is sprayed once every three days for 3-5 times totally; C, at the adult stage, the stock solution is diluted to 1300 times of the volume to be sprayed; D, after temperature is higher than 26 DEG C, spraying interval needs to be prolonged, and the number of times of spraying needs to be increased, wherein spraying is continuously conducted once every four days for 4-5 times totally. The method is simple, material matching is easy, using is convenient, leaf miner control effect is good, and control effect is improved by 12-16% compared with that of traditional pesticides.

Description

technical field [0001] The invention belongs to the technical field of vegetable pest control, and in particular relates to a method for using a calamus fly-killing composition. 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. Leaf miners can harm rice, barley, wheat, oats, etc., and feed on kangaroos, weeds, calamus, sea thorns, sweet grass, barnyard grass, etc. Milk vetch leaf miner is distributed in Zhejiang, Jiangxi, Fujian and other...

AI Technical Summary

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 calamus fly-killing composition with simple preparation method, simple proportioning of the prepared product, convenient use, and good effect of preventing and controlling leaf miners
