This invention relates to compounds of the formula: STR1 wherein R1 is an optionally substituted alkyl or alkenyl group; at least one of R2, R5 and R6 is STR2 wherein (1) when R2 is STR3 R5 is a hydrogen atom, an alkyl group or a halogen atom and R6 is a hydrogen atom or an alkyl group, (2) when R5 is STR4 R2 is an alkyl group and R6 is a hydrogen atom or an alkyl group, (3) when R6 is STR5 R2 is an optionally substituted (C1 -C6) alkyl or a (C3 -C6) alkenyl group and R5 is a hydrogen atom, a (C1 -C6) alkyl group or a halogen atom, and (4) when R2 and R6 are both independently STR6 R5 is a hydrogen atom or an alkyl group; Y is a hydrogen atom or an alkyl group; X is a hydrogen atom, a halogen atom, a trihalomethyl group and the like; and n is an integer from 1 to 3; or the agronomically acceptable alkali metal or acid addition salts thereof. These compounds are useful as chemical hybridization agents on moncotyledonous crops and are especially effective in wheat, corn, barley, rice, rye, triticale and forage crops.
