Evaluating Herbicides Efficacy Against Coffee Weeds in Southwest Ethiopia

Weed is the major limiting factor of coffee production in Ethiopia. Weeds in coffee causes 65% yield reduction in the country. Now a day, the expensiveness of weed management has been a principle issue in economic analysis of coffee production in Ethiopia. Herbicide is a best weed management option in coffee production. Thus, newly introduced herbicides verification trial was conducted in Jimma Agricultural Research Center, Agaro and Gera sub center on station in 2020 cropping season to evaluate the efficacy of newly introduced herbicides. The experiment consists six (6) treatments viz., famphosate 480G/L, Goal 200 SL, Zap weeds 200 SL, Bastnate 200 SL, Dat-phosate 41% as standard check and weedy control as negative control. The herbicides effectively reduced weed density and provide good weed control efficiency compared with weedy control. Among tested herbicides Goal 200SL, Zap weed 200Sl and Bastnate 200 SL have been showed gradual performance declination on weed control as compared with standard control herbicide. This result suggested that repeated application after a month is mandatory to achieve full control throughout season equivalent with standard control herbicide. Therefore, Famphosate 480g/l at 4.1 L/ha within 300 L/ha water with one time application per season, and Goal 200SL at 2.25 L/ha with 225L/ha water volume, Zap weed 200SL at 3 L/ha with 200 L/ha water and Bastnate 200 SL at 1 L/ha with in 300L/ha water after a month of first application recommended to control weeds in coffee. According to this study, although all the evaluated herbicides can control coffee weeds, but, the duration of their control is different. Some of them were control weed species within 7 to 21 days; others may stay and become months later.
