JPS6042308A - Rapid-acting exterminating agent for noxious mollusk - Google Patents

Abstract

PURPOSE:To provide a rapid-acting agent for exterminating slug, snail, etc., and containing 2-methylisothiazolin-3-one and/or its metal complex compound and a monohydric lower aliphatic alcohol as main components. CONSTITUTION:The titled exterminating agent contains the compound of formula (R1 is H or halogen) and/or its metal complex compound and a C1-4 monohydric aliphatic alcohol as main components. The agent exhibits rapid-acting extermination effect which cannot be expected from the experience of the separate use of individual compounds. The metallic salt forming the metal complex salt is e.g. magnesium chloride, calcium nitrate, copper sulfate, etc. The above composition may be scattered as it is or used in the form of emulsifiable concentrate, granule, liquid, wettable powder, paste, foamable agent, etc.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fast-acting agent for killing harmful molluscs such as slugs and snails, and more specifically, where R represents hydrogen or a halogen atom. ) and/or a metal complex salt thereof and a monohydric aliphatic alcohol of 01 to C4 as main components.

Mollusks such as slugs, snails, and snails are grown in fields,
They appear everywhere in greenhouses, gardens, kitchens, houses, fruit and vegetable storage areas, etc., and devour paper, wood, etc. from plants, causing a great deal of damage. In addition, because they crawl around while producing mucus, mucus contamination can cause discomfort and unhygienic feelings. In contrast, metaldehyde preparations have traditionally been used as poison baits to exterminate molluscs such as slugs, snails, and snails, but they have not been sufficiently effective, and at the same time, they do not have a fast-acting effect. There are disadvantages that are inferior to gender.

As a result of conducting a killing test on harmful molluscs such as slugs and snails, the present inventors found that the composition according to the present invention exhibits an immediate killing effect that was not expected when each compound was used alone. Based on these findings, we have completed the present invention.

The compound according to the general formula of the present invention has been developed for use as an industrial disinfectant for the purpose of antibacterial and antifungal applications in paints, paper manufacturing, cutting oil, cooling hydrogen, and the like.

On the other hand, C5 to C4 monohydric aliphatic alcohols are known to have a lethal effect on slugs, snails, and the like. However, the effect of using the above-mentioned compound as a main component to more rapidly kill harmful molluscs such as slugs and cuckoos has not yet been disclosed.

Examples of the 2-methylisothiazolin-6-one compound represented by the above general formula used in the present invention include 5-chloro-2-methylisothiazolin-6-one, 2-methylisothiazolin-6-one, and the like. In addition, metal salts that can form metal complexes with these include magnesium chloride, calcium chloride, magnesium nitrate, calcium nitrate, zinc chloride, iron chloride, calcium sulfate, magnesium sulfate, iron chloride, copper sulfate, etc. can be opened. Furthermore, the active ingredients of the invention can be appropriately blended in any proportion as desired.

When the composition of the present invention is actually used.

It may be sprayed as such (1) like a normal formulation.

It can also be used as an emulsion (two grains), an aqueous solution, an i-drug, an aqueous solution, a paste) or a foaming agent. In addition, adjuvant 2, for example,
It is of course preferable to use surfactants such as spreading agents, emulsifiers, wetting agents, and fixing agents in order to ensure the effectiveness. Depending on the purpose, other fungicides, insecticides, herbicides, fertilizers, etc. may be mixed and applied at the same time. grains, wheat husks,
It can also be combined with natural and synthetic attractants such as protein products, casein, dried yeast and essential oils to form attractive pest control agents.

The usefulness of the present invention will be shown below by Examples and Test Examples.

Example 1 An aerosol type product was prepared using a volume ratio of 50 parts of methanol, 0.5 parts of 5-chloro-2-methylisothiazolin-3-one calcium chloride, and 15 parts of fluorocarbon gas.

Example 2 An aerosol type was prepared with a volume ratio of 40 parts of ethanol, 5-chloro-2-methylisothiazolin-6-one [phase] 1 part of magnesium chloride, 1 part of surfactant, 18 parts of water, and 60 parts of fluorocarbon gas.

Example 5 50 parts of butanol, 2 parts of 5-chloro-2-methylisothiazolin-6-one magnesium nitrate.

The foaming agent had a W Ht ratio of 1 part surfactant, 1 part blowing aid, 3 parts water, 26 parts fluorocarbon gas.

Test Example 1 An effect test of the drug of the present invention against slugs and snails was conducted. For slugs, No. slugs (Agrio 1 plate d
agreNis) 10 animals were used in each group.

After being sprayed with a diluted solution of the test drug at a predetermined concentration, the animals were released in a waist-high cage with a net lid of 9 Qn in diameter.

The number of dead insects was investigated at predetermined intervals after treatment. For the untreated control, the mice were sprayed with water and then released into petri dishes in the same manner as above.

Note) Required time for 100% lethality (minutes) Test Example 2 Using the foaming agent shown in Example 6, drug formulation 1 according to the present invention,

When we conducted a test to kill them, we were able to instantly kill them.
