Compounded acaricide for farmlands and fruit trees

Abstract

The invention relates to the field of pesticide preparations and discloses a compounded acaricide for farmlands and fruit trees. The acaricide is prepared from active ingredients of etoxazole and propargite with a weight percentage ratio of (1-99):(1-99), wherein an acaricidal composition accounts for 1%-99% of the acaricide by weight. The acaricidal composition has a remarkable synergy effect, the control effect is enhanced, the use amount of effective ingredients is reduced, the generation of acaricide resistance of pests is slowed, and environment pollution is reduced. The acaricide can be used for effectively preventing the farmlands and the fruit trees from mites.

Description

[0001] This application is a divisional application with an application date of December 1, 2010, an application number of 201010568461.0, and an invention titled "a compound acaricide for farmland and fruit trees". technical field [0002] The invention relates to the field of pesticide preparations, in particular to a compound acaricide for farmland and fruit trees. Background technique [0003] There are more than 500 kinds of agricultural pest mites in my country, of which more than 40 are seriously harmful, such as spider mites, two-spotted spider mites, gall mites, panonychia, etc. They mainly harm fruit trees and cotton, wheat, vegetables, tobacco, etc. , tea, corn, soybeans, peanuts and other farmland crops. Agricultural pest mites are small in size, fast in reproduction, strong in adaptability, and easy to develop resistance. Under the most suitable conditions, the reproductive limit of one female adult mite can be as high as 10,000 per month, which is recognized as ...

AI Technical Summary

Problems solved by technology

[0005] There are many kinds of acaricides used to prevent and control pests in the market. There are highly toxic acaricides such as amidines, organophosphorus, and organochlorines that are not safe for crops; Acaricide-like, but the duration of the effect is short, it needs to be used many times, and cross-resistance has been produced

At present, most of the acaricides used to prevent and control pests are selective acaricides, with low toxicity, safe for humans, animals and natural enemies, and long-lasting acaricidal effect, such as pyridaben (sweeping mite net), propargyl acaride (mite must gram), hexythiazox, abamectin (Longweikang), etc., but some control pests are single, some have high costs, and some have high residues, and the effect on agricultural pest control is not satisfactory
