摘要： 4-Substituted 5-polycyclylpyrimidine compounds in which the 5-substituent is polycyclic and is attached to the pyrimidine moiety through an aliphatic carbon atom, such as 5-(2,2-dimethylindan-1-yl)-4-methylthiopyrimidine, were prepared and found to possess excellent herbicidal activity. The compounds are especially useful for the control of undesirable vegetation in paddy rice.

摘要： The selectivity of aryloxyphenoxypropanoate herbicides, such as methyl 2-(4-((3-chloro-5-(trifluoromethyl)-2-pyridinyl)oxy)phenoxy)propanoate, when used for the control of weeds in grassy crops, such as rice, can be improved by pre-treating the grassy crop seeds or plants with an amount of an aryloxyphenoxypropanoate herbicide sufficient to elevate the acetyl-coenzyme A carboxylase enzyme activity level, but insufficient to cause phytotoxicity.
