THE INFLUENCE OF DIFFERENT TIME OF APPLICATION AND DOSES OF GRAMAXON ON BINDWEED CONTROL

Pots experiment was carrid out at Salah aldeen prov. in 2006 summer growing season to investigate the effect of herbicide doses (150, 300, 450 cm3a.i/ha) application time (15 , 25 , 30 days intervals ) and frequent application ( without application , one , two , three time of application ) on growth of bind weed . Data wrer collected at 25th October . CRD design with three replicates was used as a factorial experiment. Unsignificant result had seen on all growth characteristic of plant with the different time of herbicide application . While the third dose of herbicide was significantly superior than other doses . The more frequency of herbicide application had significant effect on reducing plant length , dry weight , number of buds , and number of branch . The interaction two or three time of application at dose 450cm3 a.i/ ha with every 15 , 25 or 35 days duration had markedly effect on plant growth which all plants was control
