Abstract

The research was carried out in areas of production from Majibacoa Enterprise, Las Tunas province, to evaluate the effectiveness of mixtures of herbicides in weed control in sugar cane plantations, variety C 86-503 in plant cane spring, in pre-post-emergent applications in three types of soils: reddish brown Fersialitic, fluffed Brown and cromic Vertisol. In the experimental area parcels were traced, according to a Randon Blocks design with four replications, the application of the mixtures was carried out with Super Agro-16 (MATABI) backpack, when some cane stakes had sprouted and small weed existed. Were determined weed species present in the area and those which appeared after application, the percentage of coverage of the same and the toxicity caused by the herbicide mixture and its costs and the number of days it remained clean field. Six mixtures were evaluated: Ametrine + Diuron; Ametrina + 2,4-D and four doses Ametrina + Merlin + 2,4-D. The biggest doses of Merlin (Isoxaflutole): 0,150; 0,200 and 0,250 kg ha-1, this last one was the most effective in the weed control, those that caused a slight toxicity in form of small points in the leaves of the cane, the loamiest soils (Vertisol and Brown) required the biggest doses. With these doses of mixtures obtained Merlin more expensive, however, they maintained a longer period of time clean the cane field, causing the cost per day is less clean.
