Residual Herbicides and Cover Crops Interactions for Soybean Weed Control

Residual herbicides and cover crops are important tools inside an integrated weed management program. The straw produced in crop rotation can interacts with herbicides. aim of this study was to evaluate the interaction diclosulam, sulfentrazone, imazethapyr, flumioxazin, s-metolachlor pyroxasulfone black oat, cereal rye, common vetch oilseed radish it´s reflection on control soybean production. Were evaluated biomass production its influence population. A phytosociological survey community carried out, further evaluating provided by effects productivity. Diclosulam more efficient herbicide tested, reducing both density (68% 89%, respectively) compared fallow, independently straw. best levels for population identified were combination diclosulam or fallow. We observed that efficacy case related spectrum than herbicide-straw interation. This research demonstrates integration residual is suppression weeds no-tillage system.
