CONTROLLER FOR SOIL DISEASE DAMAGE

PURPOSE: To obtain a controller for soil disease damage showing excellent controlling effects on disease damage which can not be expected, having no phytotoxicity by blending 2',4-dichloro-α,α,α-trifluoro-4'-nitro-m- toluenesulfonanilide with a certain fungicide. CONSTITUTION: This controller for soil disease damage comprises both 2',4- dichloro-α,α,α-trifluoro-4'-nitro-m-toluenesulfonanilide as an agricultural fungicide and 3-hydroxy-5-methylisoxazole as an agricultural fungicide and controls disease damage of various crops and raises healthy crops in crop culture. The controller for soil disease damage may be singly applied to crops and preferably is mixed with a carrier and an auxiliary and applied in the form of dust, fine granule, granule, emulsion or flowable agent. The content of the active ingredients in the formulation is preferably 0.5-80wt.%. The blending ratio of both the compounds is (1:1)-(1:200), especially (1:5)-(1:50) by weight. The compound is effective for damping-off and clubroot of cruciferous vegetables.
