Description

[Detailed description of the device] [The purpose of the device]

[Industrial field of application] The present invention relates to a material for controlling pests of the eye eye, such as snails and slugs. [Prior Art] (1) Background Snails and slugs belonging to mollusc nets, pulmonary subclasses, stigmas have a function of secreting strong cellulase from their digestive tracts to digest fibrin. These organisms have the property of physiologically metabolizing a large amount of water, which accounts for more than 50% of the body weight of night and night, and the lacking water must be supplemented from food, resulting in damage to a large amount of plant shoots and vegetables. To do. Moreover, these animals are hermaphroditic, have strong fertility, and have no natural enemies except chickens and toads, and are therefore prone to occur in large numbers. And because it is nocturnal and hides in the shade during the daytime, it is difficult to find and kill it. (2) Problems of the Prior Art Paraformaldehyde (paraform) and methaaldehyde are conventionally used as attractant contact poisons for controlling patterned eye organisms such as snails and slugs. However, these agents cannot be said to be environmentally harmless because they volatilize formaldehyde and acetaldehyde little by little, and since they are granular, a large amount must be sprayed at the root to prevent potted plants and fruit trees from being eaten. As a result, the required drug cost becomes large. It has been practiced to lay a copper net inside the drainage port of a flower pot for a long time, but it is not effective for controlling slugs and the like that crawl on the side of the pot. Therefore, farmers who grow sweet citrus have adopted a method of surrounding the circumference of fruit trees with tape etc. impregnated with a solution of copper sulfate, but copper sulfate is quite soluble in water, so it is not frequently replaced. And no effect. [Problems to be Solved by the Invention] Therefore, the problem to be solved by the present invention is to develop a means which is effective for controlling pests of the eye-eyed eye, is sustainable, and is not dangerous to humans and animals.

[Constitution of device]

 [Means for Solving the Problem] (1) Concept The present inventor made a study on solving the above problem.
As a result, water-swellable elastomers are harmful to eye-eye organisms.
It has very favorable properties as a carrier for repellents and poisons.
