RESPONSE OF Cyperus rotundus WEEDS TO GLYPHOSATE HERBICIDE WITH SOME ADJUVANTS UNDER GREENHOUSE CONDITIONS. fl
Glyphosate is post-emergence herbicide commonly used in perennial weed control as foliar active compound. Thus recent approaches are aiming to minimize its usage even in amounts and numbers. The role of fourteen chemical adjuvants in enhancing or reducing the efficiency of giyphosate on nutsedge (Cyperus roiundus) as a dominant perennial weed was studied. The adjuvants used were: glue. ammonium sulfate, urea. diethyl ether. propanol. rape seed oil. castor oil, paraffin oil. diesel oil. mineral oil, monoethylene glycol dioleate. monoethylene glycol monoleate and glycerin. The efficacy of half rate of glyphosate with and without adjuvants compared with glyphosate recommended rate without adjuvants was evaluated on yellow nutsedge grown in pots under greenhouse conditions. The reduction percentages in weed population by the tested compounds were calculated as ratios from untreated control treatment. Using adjuvant in binary mixture with glyphosate resulted in high reduction in weed growth parameters. The maximum reduction was recorded with glycerin and followed by the surfactants monoleate. dioleate and sticking agents such as glue. urea. whereas the crop seed oil and petroleum oil came in the second category in relation to glyphosate efficiency against weeds as indicated by weed seedling parameters. i.e. fresh and dry weight. total chlorophyll and carbohydrates contents.
