PURPOSE: To obtain a wettable granule of microbicide having suppressed color change without lowering the-disintegrating and suspending property in water by using fluazinam as an active microbicidal component and preparing a fluazinam-containing composition to exhibit weak acidic state when suspended in water together with a surfactant and an extender.
CONSTITUTION: This wettable granule of an N-pyridyltoluidine-based microbicide having suppressed color change without lowering the disintegrating and suspending property in water is produced by using fluazinam [3-chloro-N-(3- chloro-5-trifluoromethyl-2-pyridyl)-α,α,α-trifluoro-2,6-dinitro-p-toluidine] as an active microbicidal component and preparing a composition of the compound, a surfactant and an extender to exhibit weakly acidic state when suspended in water at a concentration of 1%. It is preferable to incorporate the agent with other active microbicidal component such as 1-(2-cyano-2-me thoxyiminoacetyl)-3-ethylurea together with the fluazinam. The wettable granule eliminates the inconvenience of wettable powder, suspension, etc., such as the dusting trouble and the disposal of contaminated container.
