Coffee Wilt Disease has been a serious problem to the production of coffee in East Africa and other continents. In Ethiopia, annual national crop losses attributed to CWD was 3360 tone amounting to US$3,750,976. In Uganda CWD was estimated to overall effect of about 50 percent lost of the revenue expected from coffee exports. In Tanzania, CWD resulted in a financial loss of US $ 316,200 for over 10 years including US$45,000 spent in eradication. In DRC, by the mid-1990s, 90% of plantations were affected. The disease was also found to spread through contaminated soil, running water and contaminated tools. Cultural management activities like slashing and digging should be avoided in CWD-prone coffee fields, and agronomic practices (pruning and stumping) that bring about wounding in coffee trees should be done with efficiently disinfected tools. Through an attempt to controle biologically, in the use of resistance variety, lines of Coffee arabica in Ethiopia showed differences in resistance to the CWD pathogen. In Uganda few CWD resistant Robusta clones were identified and released. In Tanzania use of copper based fungicides for stem painting to prevent landing of G. xylarioides spores. |
