| Abstract | ||
| The experiment was conducted during the growing season 2011 at College of Agriculture and forestry, Mosul University (Iraq).The aim of present study is control Water Hyacinth by using glyphosate and 2,4-D herbicides at different rate ,methods and frequencies of application and with different times between application. The experiment was set out as factorial experiment in randomization complete block design with three replicates .The experiment included three factors: 1-the type of herbicide with different doses methods of application, 2-the frequency of application and 3-the period of times, to study the effect of herbicides application on characters after spraying and ropewick technical .The results showed that Glyphosate was more effective than 2,4-D in reducing fresh weight of plant and the percentage of regrowth up to 17.59. Moreover it was observed that use rope-wick wiper technique of herbicide application was more satisfactory in reducing contamination in the water, and gave same result with spraying in different period specially when use glyaphosate in rate ( 1:10)and(1:5) (herbicide : water )concentrations .Moreover, it was observed that the period between two application 15-30 days more favorable for controlling water hyacinth plant in which it gives a 92.13% control when using glyphosate at dose of 450 g/donum when applied as foliar spray and repast the tremens twice after 50 days. | ||
