Novel tetrazolinone derivatives of the formula:
wherein
R¹ represents alkyl, haloalkyl, cycloalkyl, alkenyl, haloalkenyl, alkynyl, alkoxy or phenyl which may be substituted,
R² represents alkyl, haloalkyl, cycloalkyl, alkenyl, haloalkenyl, alkynyl, alkoxy 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, and said heterocyclic ring, may be fused with carbocyclic ring and/or may be substituted by C₁₋₄ alkyl, and
R³ represents 5-membered heterocyclic ring comprising hetero atom optionally selected from the group consisting of nitrogen atom, oxygen atom and sulfur atom as well as carbon atom, and said 5-membered heterocyclic ring may be optionally substituted by substituent (s) selected from the group consisting of halogen, benzyl, phenyl, halogen-substituted phenyl, C₁₋₄ alkyl, C₁₋₄ alkoxy, C₁₋₄ haloalkyl, C₁₋₄ haloalkoxy, C₁₋₄ alkylthio, C₁₋₄ alkyl-sulfonyl and C₃₋₈ cycloalkyl,
