In this study a new formulation of EPTC, the new products glyphosate and napropamide and high rates of butilate, vernolate and EPTC were tested in purple nutsedge (Cyperus rotundus L.). The slow release formulation of EPTC was more persistant than the regular EPTC. High rates (16 kgia/ha) of the ...

The effect of shade on the growth and development of purple nutsedge (Cyperus rotundus L.) was studied to determine the feasibility of integrating cultural control (shading) with other control methods. Pots with tubers from the Departments of Córdoba and Valle were placed under shades of 0, 44, 5...
