Claim 2
Independent Claim
49 words
A method of killing plant pathogenic fungi which comprises applying to said fungi a fungicidally effective amount of a compound represented by the following formula: ##STR20## wherein each of X and Y represents oxygen or sulfur, and A represents alkylene having 3 carbon atoms which may have branched methyl.
Claim 3
Dependent Claim
17 words
The method of killing plant pathogenic fungi according to claim 1, wherein said compound is 1,2-trimethylene-4-(3',5'-dichlorophenyl) urazole.
