ABSTRACT:

TECHNICAL FIELD
The present invention relates to 1,2,3-thiadiazole derivatives and salts thereof, and agrohorticultural disease controller containing said compound as an active ingredient, and method for using the disease controller.
BACKGROUND ART
1,2,3-Thiadiazoles are disclosed in JP-A-2-149579/1990 as an agent for treating central nervous system diseases, in JP-A-54-9272/1979, JP-A-3-181463/1991, JA-A-4-234881/1992, Canadian Patent 947297, etc. as a herbicide or a plant growth regulator, and in WO 9501340 and JP-A-7-252242/1995 as a fungicide.
DISCLOSURE OF THE INVENTION
With the aim of creating a novel agrohorticultural disease controller, the present inventors have conducted extensive studies to find that the 1,2,3-thiadiazole derivatives of the present invention represented by general formula (I) or salts thereof which are novel compounds not found in literature are useful as an agrohorticultural disease controller. Based on this finding, the present invention has been accomplished.
The present invention relates to 1,2,3-thiadiazole derivatives represented by the following general formula (I) or salts thereof, an agrohorticultural disease controller containing said compounds as an active ingredient, and a method for using said disease controller:
