Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to triallyl isocyanuric acid ester (hereinafter abbreviated as "TAE").

) as an active ingredient. The TAE of the present invention is a compound known in the literature,
For example, U.S. Pat. No. 289,495 and U.S. Pat.
It is described in Publication No. 75979. According to the document, the content is a method for producing isocyanuric acid derivatives, and it is stated that the derivatives are useful as pharmaceuticals or raw materials for their synthesis, insecticides, polymers or copolymers, or raw materials for their synthesis. . However, this publication does not disclose even a single specific use of the TAE according to the present invention, and furthermore, it does not specify anything about how to use it as an insecticide. Further, the compound described in the same publication does not exhibit any insecticidal effect at the average practical concentration of existing insecticides when used in a general insecticidal method (contact application).
The present inventors discovered that TAE is a pest that parasitizes households, e.g.
Against flies, cockroaches, etc., and harmful agricultural animals such as snail beetles, woodlice, spider mites, soil nematodes, slugs, slugs, armyworms, cabbage butterflies, black-and-white planthoppers, aphids, scale insects, ants, etc. The present invention was completed based on the discovery that when orally applied, the compound exhibits excellent biological activity as a pest control agent, and has no repellent effect on harmful animals.

That is, the present invention is a pest control agent characterized by containing TAE as an active ingredient.

The TAE of the present invention is produced, for example, by the method shown by the following formula. (In the formula, x represents a halogen atom, and M represents an alkali metal.

) According to the present invention, a method of ingesting TAE alone or in a suitable dosage form orally, for example, directly ingesting TAE;
A powerful pest exterminating effect can be obtained by ingesting the compound by mixing or adhering it to bait, or by permeating it into plants.

Since the TAE of the present invention is permeable to plants,
By absorbing it through the roots, flowers, or leaves of the plant, or spraying it on the plant surface, it exhibits an excellent extermination effect on each generation of sap-sucking pests that feed on the plant.

Furthermore, by applying TAE directly or in a suitable formulation to water, it can be effective in exterminating harmful aquatic animals. In carrying out the present invention, T
AE can be used as is) or, depending on the purpose of use, can be used as a solution, wettable powder, emulsion, suspension, powder, coating agent, etc.
It is used as granules, aerosols, smoke agents, falconifiers, and various mixtures.

In particular, when used as a mixed bait, TAE can be mixed with a suitable carrier, substance, or various bases suitable for the use to form powders, granules, tablets, pellets, solutions, suspensions, emulsions, etc.
It is convenient to use it in an appropriate form such as a paste or candy. For formulation, it may be a solid, liquid or gaseous body, or a combination thereof.

Examples of the bile mentioned here include talc, clay, kaolin, diatomaceous earth, calcium carbonate, potassium chlorate, saltpeter, thick powder, nitrocellulose, starch, gum arabic powder,
Water, alcohol, kerosene, naphtha, xylol, benzene, acetone, air, nitrogen, carbon dioxide, freon, vinyl chloride, propane, butane, etc. are used. Also,
Auxiliary agents such as spreading agents, emulsifiers, dispersants, humectants, etc. may be added to the drug.

In addition, depending on the purpose of use, the above components may be combined with other insecticides,
It can also be used in combination with attractants, fungicides, herbicides, plant nutrients, fertilizers, etc. The compound of the present invention is preferably applied at an application rate of 50 to 400 per 10 ares against agriculturally harmful animals.
However, it is natural that the dosage may be adjusted within the above range depending on the type of harmful animal and its growth condition.

Next, the present invention will be explained with reference to Examples.

Next, the present invention will be explained by giving experimental examples.

Experimental example 1 Efficacy test against cockroaches TAE was placed in a plastic container with a lid of 12 diameter and low height.
A glass container was placed containing a mixed bait with a predetermined concentration, an additive-free powdered feed, and water soaked in decoction wire, and a total of 20 male and female cockroaches of one type were placed in each container. The effect was evaluated 24 hours later.

The experimental results are shown in Table 1. Furthermore, it was confirmed that this drug does not repel cockroaches by co-locating it with additive-free powdered feed.

A glass petri dish containing a mixed feed containing TAE at a predetermined concentration, an additive-free powdered feed, and 3% sugar water soaked in absorbent cotton was placed in a mesh (made of gold aluminum), and houseflies were placed in each rearing container for 4 hours after emergence. 10 male and 10 male adult worms were placed, and the effects were evaluated after 2 treatment hours.

The experimental results are shown in Table 2. Furthermore, it was confirmed that this drug was not repellent to houseflies by placing it together with additive-free powdered feed.
