High-efficiency longhorn beetle control paste with strong intake transportation characteristic and contact toxicity, and application method of paste

Abstract

The invention discloses high-efficiency longhorn beetle control paste with strong intake transportation characteristic and contact toxicity, and belongs to the field of pesticides and preparations thereof. The paste is prepared by blending the following components in percent by weight: 0.1-30% of thiacloprid, 0.1-20% of 2-phenyl-1-(5-(2-phenylethynyl)thiophene-2-yl) ethyl ketone (hereinafter referred to as PPTE) and the balance of additives. The additives comprise a solvent, an adhesive and filler, wherein the weight of the solvent, the adhesive and the filler respectively accounts for 0.1-80.0%, 0.1-80.0% and 0.1-80.0% of the total weight of the paste. The invention further discloses an application method of the paste; and when the paste disclosed by the invention is applied to the part where bark is peeled off, good adhesion and persistence are realized; pesticide application is simple and convenient; insecticide utilization rate is improved; environmental pollution is reduced; an insecticide can enter into plants through internal absorption of plant epidermis; and the paste disclosed by the invention has a certain contact toxicity so as to prevent pests from crawling up and downon a tree trunk, thus greatly reducing harm to trees.

Description

technical field

[0001] The invention relates to a high-efficiency, systemic conduction ointment for controlling long beetles and a method for using the same, belonging to the field of pesticides and preparations thereof. Background technique

[0002] Beetle is an important borer pest of poplar, willow, elm, maple and other tree species in my country. There are more than 100 kinds of beetles reported in China. Due to the secluded life of longicorn beetles, few types of natural enemies, and complex life history, poplar and willow are one of the preferred tree species for afforestation in my country, such as afforestation, windbreak and sand fixation, fast growth and high yield, resulting in sufficient food resources for longicorn beetles and serious harm to longicorn beetles in my country. , with an annual area of ​​600,000 hm 2 about. In the past 10 years, the macular beetle and the bare-shouldered beetle have spread rapidly and caused serious damage, which has greatly restr...
