Problems solved by technology

[0002] In the past, the powders with repellent effect were all spread in a certain range to repel the invasion of reptiles. However, due to the low vapor pressure of the active ingredients used in this type of powder, they were not enough to volatilize into the air to repel flying pests. As a result, the area where the powder is applied will still be infested by flying pests
The published patent CN101478880A proposes an insecticide composition, wherein the active ingredient adopts metofluthrin (metofluthrin), which can prevent flying insects from infesting, but we still feel that its medicinal effect is not ideal

Abstract

The invention provides an injurious insect repellent powder which comprises 0.01-5 percent of insect impellent effective component and the balance of powder carrier in the terms of the total weight of the injurious insect repellent powder, wherein the insect impellent effective component is pyrethroid compound A shown in the following formula, wherein R is hydrogen atoms, methyl or methoxymethyl; and the powdery carrier is an inert component which can be accepted in the pesticide science and can load or dilute the pesticide. The injurious insect repellent powder can effectively inhibit the infestation of injurious crawl insects and injurious flying insects, and is durable in pesticide effect. The invention also provides application of the injurious insect repellent powder.

Description

technical field [0001] The invention relates to a pest repellent, in particular to a pest repellent powder containing a pyrethroid compound and an application thereof. Background technique [0002] In the past, the powders with repellent effect were all spread in a certain range to repel the invasion of reptiles. However, due to the low vapor pressure of the active ingredients used in this type of powder, they were not enough to volatilize into the air to repel flying pests. As a result, it will still be infested by flying pests within the range of spraying powder. The published patent CN101478880A proposes an insecticide composition, wherein the active ingredient adopts metofluthrin (metofluthrin), which can prevent flying insects from infesting, but we still feel that its medicinal effect is Not ideal. [0003] Therefore, in order to achieve the effect of repelling both reptiles and flying insects, it must have excellent vapor pressure and high activity against pests. W...
