Results of trials with perfluidone (MBR-8251) for nutsedge (Cyperus rotundus) control in cotton


, : Results of trials with perfluidone (MBR-8251) for nutsedge (Cyperus rotundus) control in cotton. Sociedad Colombiana de Control de Malezas y Fisiologia Vegetal "COMALFI" Resumenes de los Trabajos en el VII Seminario, Bogota, 1975: 67-68

On heavy soils in Palmira rates of 4 or 5 kg perfluidone/ha were required to give moderate control of C. rotundus 40 days after treatment. Higher rates injured the cotton. Satisfactory control was obtained with perfluidone at 4 kg/ha followed by mechanical or hand weeding 30 and 45 days after treatment. Incorporation of perfluidone before sowing improved weed control but reduced selectivity in cotton.

Streambed hydraulic conductivity is a key factor influencing water exchange between surface water and groundwater. However, the streambed invertebrate bioturbation has a great effect on the hydraulic conductivity. In order to determine the impact...

The main objective of this study is to understand the adaptation to external constraints and the effects of variability in a golf putting task. We describe the adaptation of relevant variables of golf putting to the distance to the hole and to the...
