ることを特徴とするサリチオンの安定化方法に関する。Detailed Description of the Invention The present invention relates to the inclusion of 2-methoxy-4H-1,3,2-penzodioxaphosphorine-2-sulfide (salithion) with cyclodextrin. The present invention relates to a method for stabilizing salithion, which is characterized by:
サリチオンは広範囲の農業害虫に佼れた殺虫力を有し、
特に果樹跋菜の害虫防除剤として有効であるが、安定性
に乏しい欠点がある。Salicion has excellent insecticidal power against a wide range of agricultural pests.
It is particularly effective as a pest control agent for fruits and vegetables, but it has the drawback of poor stability.

し、本発明を完成した。For this reason, nitrogen-containing stabilizers for glazes have been studied, for example, in Japanese Patent Publication No. 44-28099, Japanese Patent Publication No. 47-9598, and Japanese Patent Publication No. 48-10478, but they are not sufficient. . Under these circumstances, the present inventors further investigated the stabilization of salithion, and as a result found that the stability of salithion could be improved by including it with cyclodextrin, and completed the present invention.

12IIe of a 75% acetone solution of salithion was added to g. 4[1? After continued stirring for a while, the produced scuttling was filtered and dried. The white powder thus obtained was ground into fine powder using a dry grinder. In order to remove unclathrated salithion, it was washed with diethyl ether for 2 u to obtain a β-cyclodextrin clathrate of salithion.
