Abstract

<P>PROBLEM TO BE SOLVED: To provide an unprecedented, environment-preserving and very highly safe agent, which is made from raw materials composed almost of organic substances to permit biodegradation in soil of food left over, for preventing vermin damages against vegetables and flowering plants by mollusks belonging to gastropods such as slugs, land snails, helices and the like without exerting bad influences on human beings, plants, house pets, soil and the like that slugs, land snails, helices and the like willingly ingest to die after ingestion where they were. <P>SOLUTION: The agent for preventing vermin damages against plants by mollusks belonging to gastropods such as slugs, land snails, Helicidae and the like is obtained by adding an attractant for gastropods such as soup of Lentinula edodes, an aqueous solution of a hop or the like to a mixed powder comprising 1-5% of iron phosphate, 2-5% of calcium carbonate and 90-97% of grain bran, each in terms of weight ratio, pelletizing and then drying the mixture. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

  The present invention relates to an agent for preventing damage to vegetables and flowering plants from mollusks belonging to gastropods such as slugs, snails and maimais.

In recent years, the number of people who enjoy kitchen gardening and gardening has increased, and the amount of agricultural chemicals used has increased accordingly. However, the number of safety-oriented people who want to make vegetables and flowers but do not want to use pesticides is increasing rapidly. When pesticides are not used, the damage caused by slugs, snails, maimais, etc. is enormous. These pests are nocturnal, and pesticides are commonly used for extermination. As seen in Patent Document 1, Patent Document 2, and Patent Document 3, the pesticides used include pyrethroid insecticides, organophosphorus insecticides, carbamates, liquids, powders, aerosols, and solids in use.
However, these drugs are unfavorable for pets because of their strong odor and are not environmentally preferable due to fears of phytotoxicity of plants.
Moreover, although there exists a soil treatment agent like patent document 4 with respect to a slug, a snail, a mussel, etc., these components may absorb from a plant root and may remain in a plant.
From this point of view, there are many people who are anxious about adverse effects on people, plants, pets, soil, etc. and do not want to use them.

  The present invention provides an environment-preserving and highly safe agent for plant damage caused by mollusks belonging to gastropods such as slugs, snails and mussels.

In addition to avoiding adverse effects on people, plants, pets, soil, etc., slugs, snails, maimais, etc. prefer to ingest it and die after ingestion, and most of the raw materials Since it is an organic substance, uneaten leftovers are unprecedented in that soil is decomposed.
In other words, slugs, snails, maimai, etc. are processed so that they can be ingested, they can be ingested before they cause damage to plants, and they are extremely safe without any insecticides or harmful substances. Yes, it is an environmentally friendly plant protectant that does not adversely affect people, plants, soil, pets, etc.
Moreover, since it returns to the place immediately after ingestion, there are no dead bodies, and most of the raw materials are organic substances.

The anti-corrosion agent according to the present invention is an anti-corrosion agent characterized in that iron phosphate, calcium carbonate, and mixed powder of cereal meal are mixed with shiitake broth or hop aqueous solution, processed into pellets and dried. It is about.
The purpose of adding calcium carbonate, iron phosphate and cereal meal, which are the ingredients of this agent, is described below.
First, slugs, snails, maimais, etc., which are mollusks belonging to gastropods, are wandering around the block cages, which are said to be ingesting calcium contained in the cement. Thus, slugs, snails, maimais, etc. prefer to consume calcium. Therefore, this agent has added calcium carbonate as a calcium source.
In addition, this agent contains iron phosphate. The reason for this is that slugs, snails, maimai, etc. ingest iron phosphate and immediately change its internal organs, stop eating damage and return to whereabouts. Later, slugs, snails, maimais, etc. become unable to consume food.
This agent further includes shiitake mushroom juice or hop aqueous solution as a slug attractant. Slugs, snails, maimai, etc. gather quickly and take this medicine due to shiitake mushroom soup and scent of hops.

  This agent is favored by slugs, snails, maimai, etc., and is used by people and pets that are composed of materials that naturally decompose in the soil without contaminating the surface of the soil or plants because they return to their place of death. We have made it possible to provide easy-to-use environmentally-friendly plant damage prevention agents.

Of the iron phosphates, ferric phosphate is preferably used in the present invention. Since it contains 20% or more of iron and is nonflammable, there is no particular danger. It is not harmful to humans.
This ferric phosphate is mixed with powders of calcium carbonate, rice bran, and barley straw, adjusted to a moisture content of 10-20% with 5 wt% shiitake broth, and then kneaded with a mixer to 3.5-5 mm Pelletize and finish with sun or dryer. Shiitake uses dry matter. It should be noted that shiitake mushrooms or those dried with high-temperature hot air using thermal power have little fragrance, so the amount used must be increased.
The optimum range of the blending ratio is described below.
Rice bran 35-60%
35-60% wheat straw
2-5% calcium carbonate
Ferric phosphate 1-5%
Shiitake soup 5-15%

(Adjustment of anti-corrosion agent)
After mixing ferric phosphate, powder of calcium carbonate, rice bran, and barley wheat straw, adjusting the water content to 10-20% with 5 wt% shiitake soup, kneading with a mixer and pelletizing to 3.5-5 mm, Finished by sun or dryer and adjusted for anti-corrosion agent. The blending ratio before drying is as follows.
40% rice bran
40% wheat straw
Calcium carbonate 3%
Ferric phosphate 2%
Shiitake soup 15%

(Examination in tobacco nursery house)
1. From the beginning of February, damage to tobacco seedlings occurred.
2. In the evening, this drug is sprayed around passages and tobacco seedlings.
3. No damage after spraying. No pesticide sprayed once a year.

(Test in shiitake cultivation)
1. Slugs have been infested since March every year.
2. Disperse this agent around the raw wood.
3. The eating damage decreased to 20-30% of the normal year.

(Examination in cowshed)
1. A large amount of slugs, etc. were generated in the barn because of the abundance of food.
2. Spraying the agent in the barn (1 m ² per 50 g).
3. On the third day, the remaining amount of this drug 20-30% was confirmed.
4. On the 4th day, this drug was treated in the same amount as the first time.
On the 5.6th day, approximately 50% of the remaining amount of this drug was confirmed.
6.7 Confirmed that the remaining amount on the 7th day is no different from the previous day. Effective due to reduced intake. (About 5 to 6 corpses, which are thought to have naturally declined at the place.)
Table 1 shows the intake of this drug measured in the barn.

(Examination in home garden)
1. Although many vegetable damages occurred in the vegetable garden, it was difficult to remove due to nocturnal nature.
2. This product is sprayed around vegetables, flowers and passageways.
3. Eating damage is no longer seen.

(Planter test)
1. Two pots of three petunias preferred by slugs were prepared, each of which was released 10 slugs, covered with a plastic container, and about 8 g of this agent was observed in one container without being sprayed in one container. .
2. There was almost no food damage in the container sprayed with this agent, but the petunia in the container not sprayed was damaged from the first day, and on the third day, all three were 70-80% leaves. Was found to be damaged. After 5 to 6 days, almost 100% of the food was damaged.
Table 2 shows the results.
