Abstract
Abstract Herbicidal 1,3,5-triazinediones of the formula: WHEREIN X1, X2, R1, R2 and R3 are as hereinafter defined. Certain of these triazinediones are useful for the selective control of weeds in crops, e.g. wheat and soybeans. Exemplary of the class of compounds are 1-methyl-2-cyclopentyl6-methylthio-s-triazine-2,4(1H,3H)-dione and 1-methyl-3cyclohexyl-6-methylthio-s-triazine-2,4(1H,3H)-dione, which are useful for the selective control of weeds in wheat and soybeans, respectively.
