Effect of intervals between application and tillage on glyphosate control of Cyperus rotundus L



Effect of intervals between application and tillage on glyphosate control of Cyperus rotundus L



Weed Research, UK 19(3): 207-211



Research conducted in El Salvador, Central America demonstrated that an interval of 3 days between application of glyphosate and tillage was sufficient to cause 90% reduction in purple nutsedge (C. rotundus L.) plants, while delays of 11-23 days generally gave slightly less reduction. A 2nd application to the same plots 35 days following tillage resulted in more than 90% reduction with all intervals. Approximately 3 mo. after the initial treatment, tuber numbers were reduced to half the original population. Germination of the remaining tubers was reduced by more than 50%. Glyphosate applied during the dry season caused an average of 79% reduction in plant numbers compared with 88% in the raining season. However, in the dry season, the remaining plants had no competition from other weeds and after 5 months there was only a 40% reduction in nutsedge population. During the rainy season, 1, 2 and 3 kg/ha were equally effective, but 1 kg/ha was not sufficient in the dry season.
