This invention relates to compounds of the formula: ##STR1## wherein R.sub.1 is an optionally substituted alkyl or alkenyl group; at least one of R.sub.2, R.sub.5 and R.sub.6 is ##STR2## wherein (1) when R.sub.2 is ##STR3## R.sub.5 is a hydrogen atom, an alkyl group or a halogen atom and R.sub.6 is a hydrogen atom or an alkyl group, (2) when R.sub.5 is ##STR4## R.sub.2 is an alkyl group and R.sub.6 is a hydrogen atom or an alkyl group, (3) when R.sub.6 is ##STR5## R.sub.2 is an optionally substituted (C.sub.1 -C.sub.6) alkyl or a (C.sub.3 -C.sub.6) alkenyl group and R.sub.5 is a hydrogen atom, a (C.sub.1 -C.sub.6) alkyl group or a halogen atom, and (4) when R.sub.2 and R.sub.6 are both independently ##STR6## R.sub.5 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.
本发明涉及以下式的化合物:## STR1 ##
其中R1是可选取代的烷基或烯基基团;R2、R5和R6中至少一个为## STR2 ##
其中(1)当R2为## STR3 ##时,R5为氢原子、烷基或卤素原子,R6为氢原子或烷基;(2)当R5为## STR4 ##时,R2为烷基,R6为氢原子或烷基;(3)当R6为## STR5 ##时,R2为可选取代的(C1-C6)烷基或(C3-C6)烯基基团,R5为氢原子、(C1-C6)烷基或卤素原子;(4)当R2和R6均独立为## STR6 ##时,R5为氢原子或烷基;Y为氢原子或烷基;X为氢原子、卤素原子、三卤甲基基团等;n为1至3的整数;或其农业上可接受的碱金属或酸加成盐。这些化合物可用作单子叶作物的化学杂交剂,尤其在小麦、玉米、大麦、水稻、黑麦、小黑麦和饲草作物中特别有效。
