Certain pyrazinyl 1,3 cycloalkanedione derivatives having herbicidal activity

摘要

Novel aromatic heteromonocyclic-substituted 1,3-cycloalkanediones, enol ester derivatives and salts thereof, exhibit herbicidal activity against a variety of broadleaf and grassy weeds. Certain 2-(2-pyrazinyl) 1,3-cycloalkanediones and their enol esters were also found to be active as mite adulticides and ovicides.
