Insecticide for killing termites and preparation method of insecticide

A technology of medicaments and termites, applied in botany equipment and methods, insecticides, biocides, etc., can solve the long-term problem. It takes more than 3 months to kill a termite population, and some even take nearly a year. The control effect is not ideal, and the ant colony cannot be effectively killed, etc., to achieve the effect of good control effect, simple preparation and use, and safe use

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-cy

Embodiment 1

[0018] Example 1: Measuring the Toxicity of Chlorfenapyr to Termites

[0019] test methods:

[0020] The 98.1% chlorfenapyr original drug was prepared into a series of concentrations with acetone. Use a pipette to pipette 1ml of the drug solution and evenly drop it on the filter paper (Φ9cm) to form a drug film, dry it naturally and put it into a clean Petri dish (Φ9cm). Add 1ml of double-distilled water dropwise, and put in 30 milk termite worker ants for continuous contact. 3 repetitions, set a blank control, record and observe the number of dead termites every day, and calculate the LC 50 Value, the test is carried out at 28±1°C, under dark conditions, and keep the filter paper moist.

[0021] Implementation Effect:

[0022] Table 1 Toxicity determination of chlorfenapyr original drug film method to milk termites

[0023]

[0024] It can be seen from Table 1 that after the drug treatment, the termite mortality rate was very low within 24h and 48h, and the...

Embodiment 2

[0025] Embodiment 2: the preparation of powder, used in embodiment 4.

[0026] Weigh 4000 mg of talcum powder, 80 mg of vanillin, and 454 mg of 98.1% chlorfenapyr powder, mix them together, and stir evenly to prepare 10% chlorfenapyr powder.

[0027] Weigh 4000 mg of talcum powder, 80 mg of vanillin, and 215 mg of 98.1% chlorfenapyr powder, mix them together, and stir evenly to prepare 5% chlorfenapyr powder.

[0028] Weigh 4000 mg of talcum powder, 90 mg of vanillin, and 41 mg of 98.1% chlorfenapyr powder, mix them together, and stir evenly to prepare 1% chlorfenapyr powder.

Embodiment 3

[0029] Embodiment 3: the preparation of bait, used in embodiment 5.

[0030] Pass the pine sawdust through a 1 mm sieve, place it in a constant temperature drying oven, keep it at (60±1)°C for 24 hours, and take it out for later use. Use an analytical balance to weigh 4000 mg of pine sawdust, 100 mg of vanillin, 400 mg of soft white sugar, and 290 mg of 98.1% chlorfenapyr powder, pour them into a beaker and mix well. Weigh 1000 mg of agar powder, add 30 mL of distilled water, stir and heat in a microwave until boiling, add 10 mg of sorbic acid, and stir evenly. Pour into the mixture in the beaker while hot and stir well. That is, 5% chlorfenapyr bait was prepared. Let cool and serve.

[0031] The preparation of 1% chlorfenapyr bait was the same as above, except that 56 mg of 98.1% chlorfenapyr powder was weighed.

[0032] The preparation of 0.5% chlorfenapyr bait was the same as above, except that 28 mg of 98.1% chlorfenapyr powder was weighed.

[0033] The preparation of...

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...
