DAN, H.A et al. Selectivity of clomazone applied alone or in tank mixtures to cotton. Planta daninha [online]. 2011, vol.29, n.3, pp.601-607. ISSN 0100-8358.

Clomazone is one of the most important herbicides applied in pre-emergence in cotton, even though not much is known about its selectivity to this crop. This work was carried out to evaluate the selectivity of clomazone applied alone or in tank mixtures with other herbicides applied in pre-emergence in cotton. The experiment was designed as a randomized block, with four replicates, using two-fold checks. Thirteen treatments were evaluated, constituted by different combinations of clomazone with S-metolachlor, diuron, prometryne, alachlor, oxyfluorfen, and trifluralin. After herbicide application, visual crop injury was evaluated, as well as stand, plant height, number of bolls per plant and cotton+seed yield. Clomazone alone applied at 1.00 and 1.25 kg ha-1 or associated to S-metolachlor (0.76 kg ha-1), diuron (1.50 kg ha-1), prometryne (1.50 kg ha-1), alachlor (1.44 kg ha-1), and trifluralin (1.80 kg ha-1) was selective to cotton cv. Nu-Opal. However, its association with oxyfluorfen (1.25 + 0.19 kg ha-1), with trifluralin + diuron (1.25 + 1.80 + 1.50 kg ha-1), and with trifluralin + prometryne (1.25 + 1.80 + 1.50 kg ha-1) resulted in reduced cotton yield.
