The herbicidal activity of 2-alkyl-2-cyanoacetanilides

The pre-emergent herbicidal activity of 2-alkyl-2-cyanoacetanilide derivatives (a new class of anilide herbicides) is reported and the relationship between structure and activity examined. The compounds appear to act by inhibiting development of root growth. Comparisons with 2-chloroacetanilide herbicides reveal similarities and differences which suggest that, whilst both groups may interact at a similar cellular site, a different reaction mechanism may be involved.
