Novel tetrazolinones represented by the formula
wherein
X ishydrogen, halogen, C₁₋₄ alkyl, C₁₋₂ alkoxy, C₁₋₂ alkylthio, C₁₋₂ alkylsulfonyl, C₁₋₂ alkylsulfinyl or halogeno-C₁₋₂ alkoxy,
Y ishydrogen, halogen, C₁₋₄ alkyl or trifluoromethyl,
Z ishydrogen, halogen, C₁₋₄ alkoxy or halogeno-C₁₋₂ alkoxy,
W ishydrogen, halogen, C₁₋₄ alkyl or trifluoromethyl,
T ishydrogen, halogen or C₁₋₄ alkyl,
R¹ isC₁₋₅ alkyl,
R² isC₃₋₇ cycloalkyl which may optionally be substituted by alkyl, C₅₋₆ cycloalkenyl, a bridged alicyclic group or C₄₋₆ branched alkyl,
and
R¹ and R² may form an optionally substituted cyclic group, together with the nitrogen atom to which they are bonded,
with the proviso that where R² is C₄₋₆ branched alkyl, then the total number of the carbon atoms of R¹ and R² is 7 or 8, and
with the exception of the case where
X is chlorine or bromine,
Y, Z and W are hydrogen,
T is hydrogen, chlorine, bromine or methyl,
R¹ is ethyl or n-propyl, and
R² is C₅₋₆ cycloalkyl, provided that the total number of the carbon atoms of R¹ and R² is 7 or 8,
a process for their preparation and their use as herbicides.
