Abstract
Safeners are chemicals applied to crops, usually by seed treatment, to improve their tolerance to herbicides. The objective of this research was to evaluate the potential use of dietholate as a safener for pre-emergence applications of clomazone in common beans. Treatments were arranged in a factorial combination 2 x 5 x 6 composed by two herbicide treatments (without or with clomazone at 750 g ha -1 ), five doses of dietholate (0, 125, 250, 375 and 500 g. a.i. per 100 kg of seeds), and six cultivars (Diamante Negro, Ouro Branco, Jalo Precoce, BRS Pérola, BRS Pontal and BRS Radiante). Dietholate only did not exhibit potential to protect common bean from injuries caused by clomazone, but also increase crop sensibility to the herbicide.
