| New weed management strategies are being developed to reduce the amount and cost of herbicides used within the Mauritian sugar industry. One approach consists of applying herbicides a few weeks after planting or harvest at the beginning of the critical period of weed competition, with the goal of controlling emerged weeds and providing long-term residual activity. With this objective, new herbicides Krismat (trifloxysulfuron + ametryn) and Dinamic (amicarbazone) were tested alone or in tank-mixes in both plant and ratoon cane. When applied pre-emergence to weeds, Krismat (1.5-1.8 kg a.i./ha) and Dinamic (1.05 and 1.4 kg a.i./ha) were found to be comparable to the standards. Krismat was less effective on Digitaria horizontalis and D. timorensis while Dinamic did not control Cyperus rotundus, Paspalum spp. and Kyllinga spp.; tank-mixing lower rates of the two herbicides overcame their weaknesses while maintaining a residual activity over 14 to 16 weeks. With early post-emergence applications, both Krismat and Dinamic were effective on many broad-leaved weeds and some grasses. The efficacy of Krismat on Paspalum spp., C. rotundus and other sedges, and that of Dinamic on Digitaria horizontalis compensated for their individual inefficacies when they were tank-mixed. The tank-mix, Krismat + Dinamic (1.5 + 0.875-1.05 kg a.i./ha) did not cause crop injury in young plant or ratoon cane. The efficacy (pre- and post-emergence) of the new tank-mix offers a new perspective for managing weeds in sugarcane, as delaying of the first herbicide application will result in savings of at least one herbicide treatment per season. | |
