Estudio de la suscectibilidad de las malezas al herbicida profoxydin, en aplicaciones simples y en mesclas, sobre el cultivo de arroz (oryza sativa l.)

This research work was carried out in the grounds of the Experimental Farm "San Pablo" of the Faculty of Agricultural Sciences at the Technical University of Babahoyo, located at Km. 7 1/2 in Babahoyo-Montalvo route, with geographic coordinates 010 49 'south latitude and 790 32' west longitude. The area has a tropical climate with an average temperature of 25.80 C, and annual rainfall of 2203.8 mm; with a relative humidity of 82%, evaporation of 1241.4 mm and a height of 8 m The floor is flat topography, clay loam texture and regulate drainage. Certified seed variety Iniap 15 was used, whose Treatments were mixtures of herbicides applied in post-emergencies such as: profoxydim (300 cc); Profoxydim + Pendimentalin (300 cc + 3 L); Profoxydim + butachlor (300 cc + 3 L); Profoxydim + clomazone (300 cc + 3 L); Profoxydim + Benthiocarb (300 cc + 3 L); Profoxydim + penoxulam (300 cc + 3 L); Pendimentalin + butachlor (Witness) (300 cc + 3 L) and mechanical Control (3 weeding) plus experimental block design was used completely randomized with 8 treatments and 3 replications, whose comparisons of means were performed with test Duncan's multiple range.......
