The place has a tropical climate with an average temperature of 25,5 oC, an annual rainfall of 2791,4 mm/year, relative humidity of 76 % and 1006,1 hours of heliophany annual average. This work was conducted to determine the effects of co-formulated herbicides for weed control in rice cultivation, INIAP 15; identify the most effective treatment in controlling weeds and economically analyze treatments. Certified seed of the variety INIAP 15 was used, with the aim of studying herbicides based coformulated Propanil for planting, as Sulfonyl are composed Crystal rice, Pamex, Propacet, at doses of 4,0 L / ha as conventional treatment Bengal + Checker, at a dose of 1 L + 250 g, the results were tabulated by the experimental design of randomized complete block, with five treatments (coformulated herbicides) and five repetitions. Comparisons of treatment means were performed with the Tukey test at 95 % probability........ |
