Insecticide for killing termites and preparation method of insecticide

Abstract

The invention relates to an insecticide for killing termites and a preparation method of the insecticide. The powder comprises the following components in parts by weight: 1-10 parts of 98.1% chlorfenapyr raw powder, 1.7-2.5 parts of vanillin and 88-97 parts of talcum powder. The powder is prepared by evenly mixing and stirring the components. The bait comprises the following components in parts by weight: 0.1-5 parts of 98.1% chlorfenapyr raw powder, 68-73 parts of pine sawdust, 6-8 parts of soft sugar, 17-19 parts of agar powder, 0.1-0.2 part of potassium sorbate and 1.7-1.9 parts of vanillin. The preparation method of the bait comprises the following steps: weighing and evenly stirring 98.1% chlorfenapyr raw powder, pine sawdust, soft sugar and vanillin; weighing agar powder and adding distilled water and evenly mixing, and heating to starchiness; adding potassium sorbate and evenly mixing the mixture; then mixing the mixture obtained from the former with the mixture of 98.1% chlorfenapyr raw powder, pine sawdust, soft sugar and vanillin; and processing the mixture obtained from the former into strips, bulks or balls to prepare the insecticide. The insecticide has the beneficial effects that: the effect for killing termites is good; the usage amount of the insecticide is greatly reduced and the environmental pollution is effectively lessened; and the preparation and the usage method are convenient, simple and rapid.

Description

technical field [0001] The invention relates to the technical field of pest chemical control, in particular to a termite exterminating agent and a preparation method thereof. Background technique [0002] Termites are one of the world's pests. my country is one of the countries with serious termite damage. 40% of the land is distributed, especially in the south of the Yangtze River. Termites can cause houses to collapse, damage home decoration, and cultural relics. Trees and crops die in large numbers, and even cause serious consequences such as piping and collapse of embankments and dams in rivers and reservoirs. According to statistics, the annual economic loss caused by termite damage is as high as 2 billion to 2.5 billion. At present, termite control in my country is divided into two parts: termite prevention and termite extermination. appear on the target. Termite control means that after termite damage occurs on the target object, corresponding measures are taken in t...

Problems solved by technology

The active ingredients of the first agent are pyrethroids, which are repellent to termites, so the effect on termite control is not satisfactory

Although fipronil has low repellency to termites and slow lethal effect on termites, its knockdown effect on termites is relatively fast, which is not conducive to the transmission of the poison of the poison-carrying termites in the entire ant colony, that is, termites The virulence transfer effect on it is small, so it cannot effectively kill the entire ant colony

There are three main active ingredients in registered baits, namely 0.5% hexaflumuron, 0.1% hexaflumuron, and the compound drug of tetramethrin and cis-cypermethrin, among which the first two agents have a particularly long effect on termites , It takes more than 3 months to kill a termite population, and some even take nearly a year, which is difficult for residents or customers to accept. The third type of agent is pyrethroids, which have a repellent effect on termites and are used as baits. not ideal

Therefore, there are few ideal powders and baits for termite control at present, and the selectivity is low.

At the same time, a large number of practices have also proved that these agents are used in the treatment of termites, and their effects are difficult to compare with the past arsenic trioxide and mirex.
