It is known that chloracetamide derivatives have herbicidal activity (Herbicide Directory No. 1, 2.2/page Hakuyusha). Among these, there are many compounds that are in practical use as herbicides for paddy fields or field cultivation. However, even though they are the same chloracetamide derivatives, their effects, selectivity for crops, fields of application, and treatment methods are completely different due to slight structural differences, making it difficult to predict the herbicidal effects of new fc derivatives. . In addition, N-Ptoxymethyl-cochlorine is currently used as an initial herbicide for paddy fields! , A'-diethylphenylacetamide (tutachlor) also has a strong herbicidal effect on a wide range of weeds, but has problems such as growth inhibition in paddy rice.
