Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention mainly relates to a termite control agent that damages buildings.

(Prior Art) Inorganic and organic chemicals are used as termite control agents, but the chemicals that are effective against termites are generally highly toxic. For example, organic chlorine-based chlordane is mainly used as a termite control agent for houses, and although chlordane is effective against termites, it is highly toxic to humans.

(The problem that the invention aims to solve) Termites can damage any plant or animal material, so the damage is widespread, such as buildings, furniture, tatami mats, wood, etc.
It can occur on railroad ties, piles, etc., but even concrete, mortar, plastic, etc., which are considered unlikely targets, can also be damaged.

The termite control agent is preferably a long-lasting agent that is effective against termites and has an anticidal effect for a long period of time.Currently, inorganic and organic agents are used, but among these, organic chlorine Chlordane of the series is mainly used.

These chemicals are applied to target buildings, mainly to the lower parts of buildings, or are injected or irrigated into wood, concrete, or soil. In addition, in areas where termites are newly introduced, underground cables, etc., the chemical may be mixed well with the underground soil before treatment.

However, these chemicals are currently becoming a major problem because they leak out of buildings and soil, contaminate the environment into groundwater and soil, and have negative effects on the human body.

Chlordane is highly toxic, and there is a desire for a low-toxicity insecticide to replace chlordane that is highly safe and effective as a long-term mountain-opening ant agent.

(Means for Solving the Problem) The present invention was made to solve these conventional problems, and contains an insecticide and glass fiber powder, and if necessary, a higher alcohol or (and ) by adding fatty acids.

Motoyama ant control agent is an insecticide that adds glass fiber powder to the insecticide to significantly enhance the termite control effect of the drug.

For example, the termite control effect can be significantly enhanced by adding glass fiber powder to Sumithion, Ditate, Maranen, Hydit, Langard, Reldan, Erzan, Bassa, and other agents known as insecticides.

Of course, chlorde, which is conventionally used as a Danzan ant agent,
Drugs such as Darzpan also have a significant enhancing effect. The experimental results are shown in Table I.

Table ■ Result of test for enhancing insecticidal power by blending glass fiber powder Table 1-1 1. Oil agent method: Spray uniformly and reciprocally under the same conditions using a spray gun: nozzle diameter 14 m on one side of a roughly cut pine wood board (150 x 1000 x 10). Next, the inner surface of a plastic petri dish with a hole drilled in the center of the top surface was treated in the same way and placed in a row, and adult house termites (ring ants) were released from the hole, sealed with a piece of gauze to ensure good ventilation, and after 1 day the number of dead insects was counted. Examined.

The study was repeated several times using 30 animals in triplicate in each ward.

Results: Significant effects were observed when using glass fiber powder with an average fiber diameter of 10μ±3μ and an average rut fiber length of 70μ±20μ with both ends sharp. A 3-chi mixture of S. mithione showed the same insecticidal power as a 2-thi mixture of Chlordan.

Scatter it on the board in the same way. Similarly, the number of dead insects was examined one day after releasing them from the hole. In the test, 30 animals were tested in each area in triplicate and repeated studies were conducted.

Results: Sumithion Emulsion 30 is considered to be practically usable compared to the conventional EC15-OG if it is -200,X10 or higher. However, the selection of emulsifier is important.

In other words, it is possible to control white ants and termites by reducing the amount of active ingredients used for termite control agents, and by reducing the amount of active ingredients, the negative effects on the environment and the human body can be reduced. can.

In addition, the present invention has many advantages, since it is now possible to use a chemical that has not been very effective as a termite chemical in the past due to its enhanced effect.

When higher alcohols are further added to the main insecticide and glass fiber powder, the ant-killing effect is further enhanced. Table ■ shows the test results.

Table ■ Supplementary effect test on termiticides containing higher alcohol A substance that dissolves the beeswax/wax layer that covers the termite epidermis, making it easier for glass fiber powder to penetrate and promoting the penetration of chemicals.

oil agent Method: Same as Table I-1 Results: Effects were observed.

Addition of fatty acids also enhances the preventive and termiticidal effects. In other words, by blending fatty acids, a layer of metal soap is generated on the surface, which removes the moisture necessary for termites to live and protects them from habitats (kitchens, bathrooms, toilets, etc.).
This not only dries out the surrounding area and worsens termite habitat conditions, but also prevents the decomposition of the insecticidal component and enhances the sustainability of the termite-killing effect of the chemical. A termite control agent may be prepared by adding higher alcohol and fatty acid together. Table ■ shows the test results.

Table ■ Effect of preventing decomposition of active ingredients due to fatty acid combination 0 Test piece; Pine wood (20 x 15 x 5 ■) Large square plastic container (600 x 500 x 200) with lid. The test pieces were separated and left on a drainboard that was filled with water and supported like an inner lid.

0 analysis method; gas chromatograph ECD and FPD (
FID) (Company) Based on the results of conventional decomposition prevention tests for various pesticides, it has been inferred that the effects shown by the former husband are due to fatty acid metals that are inert to the surface acidity at the interface between the additive ingredients and concrete, wood, soil particles, etc. This is thought to be due to the lack of contact with and isolation from moisture, air, and other active substances due to the intervening soap layer.

Glass fibers are particles having a shape that easily sticks to the epidermis of termites, and can be used in a size of 50 to 200 μm, preferably 50 to 90 μm. Use this as a powder. The amount of glass fiber powder used varies depending on the dosage form of the drug and the insecticide used. Glass fibers of 50 strands or less are usually used in formulations of unexploded and obvious ant control agents. As the higher alcohol used in the present invention, alcohols generally called higher alcohols can be used, such as 2-offyldodecanol (oitanol), isocetyl alcohol, and the like.

By blending fatty acids, the following effects can be mainly achieved. ■It prevents the decomposition of drug ingredients and increases residual effectiveness, which is especially noticeable for low-toxicity organic phosphors, and can be comparable to the use of chlordane alone, and can partially replace toxicity and reduce environmental pollution. is possible. ■Foundation concrete, especially for partitions in bathrooms, toilets, etc. A calcium metal soap layer is formed on the surface layer of wooden parts such as concrete walls, pillars, boards, etc., which promotes dryness, which is the weak point of termites, and creates a habitat condition for termites. ■Furthermore, in sub-bed soil treatment, a water-blocking and water-repellent soil surface layer is formed that prevents and retains the subsurface seepage (elution) of additive ingredients, thereby solving the major problem of environmental pollution.

Glass fiber powder can be made by the following Shinsho method.

Glass fibers are crushed using a roller mill placed in a liquid to which a dispersant is added to create a thick liquid suspension. The surfaces of the two thick rollers are carved with fine linear irregularities parallel to the shaft, and are cut into a constant width without slipping, allowing large particle distribution and small particles to be separated by sedimentation. , it is possible to formulate fine-textured formulations.

It is crushed, dispersed, concentrated, and separated during the night, so there is no scattering into the air.

Glass powder that adheres to insect bodies exhibits insecticidal effect with only 1 to 3 particles. The insect body is small, and one piece of glass powder is scaled up for a termite, and when compared to a human being, it is comparable to the damage caused by one large poisonous arrow piercing the body. be scientifically weighed.

The standard for calculating the concentration of the glass powder to be added to the spray liquid is a moderately high concentration, but the highest concentration that matches the formulation conditions should be used for calculation purposes. The size of the particles is fine, but it is desirable that the particles be elongated and have sharp ends.

The termite control agent of the present invention is composed of a base insecticide, glass fiber powder, fatty acid, and higher alcohol, or a pesticide, an auxiliary agent known as a termite agent, such as a diluent, a solvent, It is further blended with fungicides, preservatives, surfactants, etc., and processed into formulations commonly used as termite agents, such as wettable powders, emulsions, powders, oils, pastes, and aerosols. It can be used as it is, or after being suspended in water, etc., it can be sprayed, applied, irrigated, or injected. still,
It is also possible to use a formulation that does not contain the main additive and add it to conventional termite control agents or agricultural chemicals as an auxiliary agent during application, allowing for control methods tailored to the current situation.
