摘要:
A herbicidal composition comprising a herbicidally effective amount of N-halogenoacylanilino-fatty acid or the ester derivative thereof represented by the general formula: ##STR1## wherein R.sub.1 and R.sub.2 each represents C.sub.1 -C.sub.4 allyl, R.sub.3 represents a hydrogen atom, alkyl having up to 10 carbon atoms, C.sub.3 -C.sub.5 alkenyl, C.sub.3 -C.sub.4 alkynyl or cyclohexyl, R.sub.4 represents lower alkyl substituted by 1-4 halogen atoms and Y represents C.sub.1 -C.sub.3 alkylene, as an effective ingredient, and a herbicidally effective inert carrier.
摘要:
The present invention relates to compounds of the formula: ##STR1## wherein R.sub.1 is lower alkyl, lower alkenyl, lower alkynyl, cycloalkyl, unsubstituted aralkyl, lower alkyl or halogen-substituted aralkyl or halogen-substituted alkenyl; R.sub.2 is lower alkyl; Y is hydrogen or methyl and X is lower alkyl; n is an integer of 1 to 5, and a method of producing these compounds. These compounds are eminently suited for killing weeds, injurious insects, nematodes and acaricides.
