PREVENTIVE AGAINST BLIGHT AND FLY FOR AGRICULTURAL AND HORTICULTURAL APPLICATION

摘要

PURPOSE:To specific nitrided silicon hydrochloride and raw fish are subjected to fermentation and the product is used as the effective ingredient of title preventive against blight and fly caused by insects and acarids. CONSTITUTION:A silicon chloride as tetra-. hexa-, or octachloride, is previously brought into contact with the air. To the product is incorporated 2% or more amount of hydrogen chloride gas and they are made to react with hydrogen at a temperature over 200 deg.C to form a liquid silicon hydrochloride. The liquid product is gasified and dissolved in water, made to react with hydrazine, finally neutralized by adding an alkali to give a nitrided silicon hydrochloride, which is transparent liquid with a pH of 7.0 and specific gravity of 1.0. After diluted with water, the whole part, guts or fleshes of raw fish are added and they are subjected to fermentation and the product is used to produce said preventive.
