Allophanates of the formula: ##EQU1## wherein: THE X's are oxygen or sulfur; R.sub.1 is hydrogen, certain organic radicals, or halogen; and R.sub.2 and R.sub.3 are certain organic radicals, Are useful for the control of flowering and plant sexual reproduction. A preferred use of the compounds of the present invention is to prevent corn inbreeding by applying the allophanate to the plant at or shortly before tassel emergence. Exempliary of such compounds is: ethyl 4-[1-(4-chlorophenylcarbamoylimino)-1-(methoxy-methyl)]allophanate.
公式为:##EQU1## 其中:X是氧或硫;R.sub.1为氢,某些有机基团或卤素;R.sub.2和R.sub.3是某些有机基团。这些异腈酸酯化合物对于控制植物的开花和性繁殖是有用的。本发明化合物的首选用途是通过在玉米抽穗前或抽穗时向植物施加异腈酸酯来防止玉米自交。其中的示例化合物为:乙酸乙酯4-[1-(4-氯苯基氨基甲酰亚胺)-1-(甲氧甲基)]异腈酸酯。
