Efeito residual de flumioxazin sobre a emergência de plantas daninhas em solos de texturas distintas
[Residual effect of flumioxazin on weed emergence in soils of distinct textures]
Planta Daninha 27 (1), 191-196
Abstract: This work aimed to evaluate the residual effect of flumioxazin on weed emergence in soils of distinct textures. Treatments were constituted by the combination of four periods of application (14, 10, 7 and 0 days before sowing) with two rates of flumioxazin (25 and 40 g ha-1), and no herbicide application for each weed species in soils with distinct textures. Residual activity of flumioxazin was evaluated by counting the emerged weeds for each species at 35 days after sowing. Control of initial flows of weed emergence varied with soil type, period of time between herbicide application and weed sowing. A. tenella, D. horizontalis, D. insularis, D. tortuosum, E. heterophylla, N. physaloides and S. latifolia, in both soils, were the most susceptible species to flumioxazin, applied at 25 and 40 g ha-1.
