Herbicidal compositions containing tetrazolinone compounds and antidotal compounds therefor to reduce injury to various crops, particularly corn, wheat, rice and soya, from the phytotoxic effects of tetrazolinone herbicides when used alone or in combination with additional pesticidally active ingredients. Methods for reducing phytotoxicity or injury to crop plants, particularly corn and soya crops, due to tetrazolinone herbicides are also described.

Herbicidal compositions of tetrazolinone herbicides and antidotes therefor

4-substituted pyridyl-3-carbinols of the formula ##STR1## wherein R is hydrogen, or an acyl, alkyl or carbamyl group exhibit desirable preemergent and postemergent herbicidal activity. Also disclosed are herbicidal compositions comprising such compounds and methods of controlling undesirable vegetation employing such compounds. The compounds wherein AR is hydroxyl serve as useful intermediates for the production of the alpha-benzyl substituted compounds as well as exhibiting herbicidal activity.
