CONTROLLING AGENT AGAINST PLANT BLIGHT CONTAINING CLATHERATE COMPOUND AS ACTIVE CONSTITUENT

摘要

PURPOSE:A controlling agent against plant blights, containing 1,2,5,6-tetrahydro4H-pyrrolo[3,2,1-i,j]-quinolin-4-one, known as a germicide having low toxicity and penetrating property, and trapped as a clathrate compound in beta-cyclodextrin, and having a lasting property. CONSTITUTION:A controlling agent against plant blights containing a clathrate compound obtained by adding 1,2,5,6-tetrahydro-4H-pyrrolo[3,2,1-i,j]quinolin-4-one to a saturated aqueous solution of beta-cyclodextrin, and agitating the solution as an active constitutent. The resultant germicide in the form of the clathrate compound is capable of preventing the volatilization of the active constituent, improving remarkably the residual effect and continuing the effect stably for a long period.
