Summary of the invention
Novel tetrazolinone derivatives of the formula:
wherein
R¹ represents alkyl, haloalkyl, cycloalkyl, alkenyl, haloalkenyl, alkynyl or phenyl which may be substituted,
R² represents alkyl, haloalkyl, cycloalkyl, alkenyl, haloalkenyl, alkynyl or phenyl which may be substituted,
R¹ and R² may form, together with the nitrogen atom to which R¹ and R² are bonded, a 5- or 6-membered heterocyclic ring, said heterocyclic ring may be benzofused and may be substituted by one or more C₁₋₄ alkyl,
R³ represents nitro, halogen, alkyl, haloalkyl, alkoxy, haloalkoxy, alkylthio or phenoxy,
and
n represents an integer of 0, 1, 2 or 3, and when n represents 2 or 3, then R³ may be same or different,
and their use as herbicides.
