Abstract

The preemergence herbicidal activities of 10 4-(methylsulfonyl)-2,6-dinitro-N,N- variously substituted anilines were determined on four plant species at four equimolar concentrations in nutrient solution. Several analogs were as active or slightly more active than 4-(methylsulfonyl)-2,6-dinitro-N,N-dipropylaniline [nitralin]. Most amino groups on these compounds were of a mixed nature. Preemergence toxicity decreased when the N-substituents contained more than six carbons or less than five.
