Abstract

PURPOSE:A termite controlling agent containing 2-tert-butylimino-3-isopropyl-5- phenyl-3,4,5,6-tetrahydro-2H-1,3,5-thiadiazin-4-one as an active constituent with low toxicity. CONSTITUTION:A termite controlling agent, containing 2-tert-butylimino-3- isopropyl-5-phenyl-3,4,5,6-tetrahydro-2H-1,3,5-thiadiazin-4-one (buprofezin) as an active constituent and effective also as food poison and contact agent. The antproof agent is used in the form of dust and wettable powder and the compounding ratio of the buprofezin is >=1wt%. An organic material, e.g. wood meal, wheat flour, rosin, etc., and inorganic material, e.g. clay, talc, diatomaceous earth, etc., are used as a diluent. Butylcarbitol, turpentine oil, etc., may be added as a compound attracting termites.

Description

Detailed Description of the Invention (Industrial Application Field) The present invention relates to 2-tert-butylimino-3-isopropyl-5-phenyl-3,4,5,6-tetrahydro-
The present invention relates to a termiticide characterized by containing 2H-1\5-thiadiazin-4-one (hereinafter referred to as buprofezin) as an active ingredient.

(Conventional technology) Termites are pests that often live in broken earth, and they prefer sunny, humid, and relatively warm places. It eats away at parts and causes severe damage to buildings. The damage is said to reach tens of billions of yen annually, making prevention and control an extremely important issue.

When termite control agents are classified based on their usage, they are broadly divided into water treatment agents, soil destruction treatment agents, and food poison agents. In Hikari, Shikoku, Chugoku, and southern Kinki, where the Japanese termite is subject to control,
Until recently, arsenic compounds classified as food poisons were used. However, since its use has now been banned, weakly effective boron compounds and the termite agent chlordane, which has no pre-meal action, are used as food poisons. However, since these drugs do not have sufficient efficacy, there has been a strong demand for food poisoning agents with low toxicity and excellent efficacy.

(Objective and Structure of the Invention) The present inventors have conducted extensive studies in search of a low-toxicity and highly effective food poison, and have found that buprofezin is a low-toxic termite control agent that can be used not only as a food poison but also as a food poison. The present invention was completed by discovering that it is also effective as a drug. Puprofuedin is widely used as an insect repellent for rice planthoppers and leafhoppers under the trademark ``Abroad,'' but it could not have been predicted based on conventional knowledge that it would be effective against termites. That's true.

According to the present invention, a termiticide containing buprofezin as an active ingredient is used in the form of a powder or a wettable powder, and the blending ratio of buprofezin is arbitrarily selected within the range of 1% by weight or more. Diluents used in the present invention include wood flour, wheat flour, rice flour,
Examples include M-containing materials such as pine tar and cellulose powder, and inorganic materials such as clay, talc, charcoal & calcium, cane earth, and graphite.

In the present invention, butylcarpitol, ethylcarpitol, α-hinene, terpene oil, rosin, a-edenoic acid, tall oil, ethyl diglycol, butyl p-oxybenzoate, etc. are added as compounds that attract termites. Good too.

(Examples and Test Examples) Examples and test examples of the present invention are shown below, but the invention is not particularly limited thereto.

Example 1 Buprofezin 25 parts Clay powder 75 parts Mix evenly to make a powder.

Example 2 Buprofezin 25 parts Flour 75 parts Mix evenly to make a powder.

Example 3 25 parts of buprofezin - 74 parts of ethylcarpitol and 1 part of ethylcarpitol were uniformly mixed to form a powder.

Example 4 10 parts of buprofezin and 90 parts were uniformly mixed to form a powder.

Example 5 Buprofezin 5 parts - 95 parts were uniformly mixed to form a powder.

Example 6 Buprofezin 25 parts diatomaceous acid ±
70 parts of a mixture of polyoxyethylene alkylphenyl ether and alkylbenzene sulfonate 5 parts are mixed uniformly to prepare an irrigation agent.

Test Example 1 Anticide effect on colonies inside the container A vinyl chloride container (B27 crIL x width 20 CIIL x height 51) has a chemical in one corner, a piece of wood to serve as bait in the other corner, and a moisture-absorbing degreaser for water supply on the other side. I put my face on it. 50 domestic termites and 10 soldier ants were placed in this container, and the top of the container was covered with a vinyl sheet with many small holes for ventilation.

The number of knockdowns, deaths, and abnormal insects were determined over time.

(1 ward double system). The results are shown in Table 1.

Test Example 2 Diameter in Petri Dish for Transmission of Insecticidal Efficacy? 15 m of water was dropped onto C11E p paper, and the worker ants that died in Test Example 1 were added thereto at a ratio of 1:4 to the untreated worker ants to investigate the propagation of the insecticidal effect. Table 2 shows the results of the 1st ward trifecta.

Test Example 3 Anticidal Efficacy Test A drug diluted to a predetermined concentration was dropped onto a piece of paper with a diameter of 9 cWL in a Petri dish, and 30 worker ants and 20 nymphs were added thereto.
The head was released with insects, and the mortality rate was determined every week. The results are shown in Table 3.

(Effects of the Invention) As mentioned above, the compound of the present invention has a low toxicity and anti-termite effect, and also has a propagating insecticidal effect, so it is useful as a termite control agent because it can exterminate the colony itself. .
