Abstract

In pot experiments, the influence of using different concentration of the pre-emergence herbicide perfluidone (250, 500 and 750 ppm) alone or in combination with 1 % urea as well as the new post-emergence herbicide nominee (400, 600 and 800 ppm) alone or in combination  with 1 % urea, was studied on the growth and propagative capacity of purple nutsedge (Cyperus rotundus L.). Generally, the  perfluidone and  nominee alone or  mixed with 1 % urea inhibited significantly the growth of foliage as well as the underground propagative organs of purple nutsedge. Moreover, the highest concentration of perfluidone alone (750 ppm) or mixed with 1 % urea (750 ppm + 1 % urea) and the highest concentration of nominee alone (800 ppm) or mixed with urea (800 ppm + 1 % urea) completely inhibited the formation of new propagative organs. The herbicide perfluidone did not adversely affect the viability of the dormant buds of the mother tubers, while the herbicide nominee adversely affect the viability of buds of the mother tubers.
                The two herbicides alone or in combination with 1 % urea were effective in controlling the growth and propagative capacity of purple nutsedge.
                The results also indicate the superiority of using the post-emergence herbicide nominee since it affected the viability of dormant buds of the mother tubers
