Abstract

PROBLEM TO BE SOLVED: To obtain a water-based microbicidl composition for horticulture which improves extremely the storage stability of microbicidal active components and can be directly sprinkled on plants by adding a specific components stabilizer into a microbicidal composition for horticulture diluted with water. SOLUTION: A components stabilizer is formulated with the system consisting of a microbicidal active component, a surfactant and water. As the component stabilizer, acids are suitable and particularly at least one kind of acid selected from organic acids such as citric acid, malic acid, succinic acid, maleic acid and glycolic acid and inorganic acids such as boric acid, phosphoric acid and sulfuric acid is preferable. It is preferably formulated in a proportion of 0.001-0.1wt.% and the pH of the preparations in this case is preferable to be in a range of about 2-6. As the microbicidal active components, e.g. polyoxin B and streptomycin are illustrated and formulated in a proportion of about 0.01-0.1wt.%. As the surfactant, e.g. polyoxyethylene alkyl ether and polyoxyethylene alkyphehyl ether are illustrated and formulated in a proportion of about 0.001-0.1wt.%.

Generally, an aqueous horticultural drug diluted in advance to a concentration that can be directly sprayed without dilution with water has a low content of the active ingredient, so that the stability of the ingredient in water is reduced. Things are known. Therefore, there is a problem that a preparation simply diluted with water cannot be put to practical use. In order to use the aqueous bactericidal composition more easily, an aqueous preparation which can be directly sprayed on a plant without being diluted with a large amount of water at the time of use, and which is stabilized without the bactericidal active ingredient being decomposed for a long time is desired. ing.
