| Abstract | The association of glyphosate and diclosulam in burndown can reduce the presence of weeds for a longer period, thus promoting the development and productivity of soybean plants. The objective was verify if the efficiency of the herbicide diclosulam associated with glyphosate, in burndown for direct seeding, in the seed bank of weeds in soybean grown in the plant system and apply. The straw present was Urochloa ruziziensis at 4.4 t ha -1 of dry mass, uniformly distributed over the experimental area. The experimental design was randomized blocks design with three treatments and four replications. The treatments consisted in the application of glyphosate at 1.2 kg ha -1 acid equivalent (a.e.) + diclosulam 25.2 g ha -1 active ingredient (a.i.) in pre-sowing without the complementary application, glyphosate at 1.2 kg ha -1 + diclosulam 25,2 ha -1 in pre-sowing of the culture + 1,2 kg ha -1 of glyphosate in complementation and glyphosate at 1.2 kg ha -1 in pre-sowing + glyphosate at 1.2 kg ha -1 in complementation. It were evaluated the initial reinfestation and relative density of weeds at 31 days after burndown, reinfestation of weeds at harvest time, difficulty of mechanized harvesting, number of pods per plant, 1000 grain weight and productivity. The association of the herbicides glyphosate and diclosulam assists in the initial management of weeds in soybean, without, however, dispense the complementary application of glyphosate. |
