Composite miticide for farmland and fruit trees

Abstract

The invention, relating to the field of pesticide preparations, discloses a composite miticide for farmland and fruit trees. The active components of the miticide comprise 1-99 wt% of etoxazole and 1-99 wt% of one component selected from avermectin, azocylotin, propargite, clofentezine or pyridaben, wherein an acaricidal composition comprises the active components, and the acaricidal composition accounts for 1-99 wt% of the miticide. The acaricidal composition has obvious synergistic effect, increases the control effect, reduces the dosage of the active components, delays the generation of pest resistance, and reduces the environmental pollution. The miticide disclosed herein can effectively control farmland and fruit tree mites.

Description

technical field [0001] The invention relates to the field of pesticide preparations, in particular to a compound acaricide for farmland and fruit trees. Background technique [0002] 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 the most difficult pest to control. Biomes. [0003] Pest mites mainly harm crops and fruit tree leaves. The harm characteristics of most agricultural pest mites are very similar. When harming, they all pierce the ep...

Problems solved by technology

[0004] 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 is short, it needs to be used multiple times, and cross-resistance has been produced

At present, most of the acaricides used to prevent and control pests are selective acaricides, which are low in toxicity, safe for humans, animals and natural enemies, and have a long duration of killing acaricides, such as pyridaben (sweeping mite net), propargyl acaride (mite must grams), 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.
