Description

DETAILED DESCRIPTION OF THE INVENTION [0001] TECHNICAL FIELD The present invention relates to lipophilicPyrethroy
PesticidesToxicity of pesticide preparations containing seafood to fish and shellfish
How to mitigate. [0002] 2. Description of the Related Art In recent years, pesticide activities such as insecticide, sterilization, and weeding have been conducted.
Have been developed and exhibit excellent effects
There are not many things. However, many of these
Because it is highly toxic to seafood, it can be used in paddy fields.
It is applied only to wounds, fruit trees and soybeans. So
The drawback here is that these pesticides cannot be used in paddy fields.
Efforts to overcome have continued. Toxicity to seafood
As a method of mitigating this problem, the conventional method of
Method to control elution to liposomes and reduce toxicity
A method of adding a drug has been considered. about
For example, fish toxicity of thiol carbamate herbicides
(Japanese Patent Application Laid-Open No. 59-167507) is known.
Fish poison that is only
Sex relievers have not yet been found. On the other hand,
In addition, many studies are
Is being done. For example, the active ingredients are activated carbon and vegetable oil
(JP-A-56-169601),
A mixture of a petroleum resin and a surfactant in a neutral component
No. 50-6725), active substance is formed on granular material having concave portions.
Adsorbed by a liquid (JP-A-58-23361)
Are known, but none of the effects are constant or
The effect is not enough. [0003] SUMMARY OF THE INVENTION The present inventors have,parentOily
