Effectiveness of new and recommended fungicides in controlling coffee berry disease during 1981
During 1980/81 field trials the new fungicides MK-23 75 WP and A6097A 25 E.C. were found effective against Coffee Berry Disease (CBD) but both products at the rates tested gave lower yields compared to the standard product Captafol 80 WP (Chevron). Calirus 50 WP was found ineffective against CBD and gave very low yield. Dyrene 50 WP and Dyrene 75 WP gave satisfactory control of CBD and recorded yields as high as the standard product Captafol 80 WP. Copcel 50 WP controlled CBD effectively and gave yields significantly higher than the standard product Captafol 80 WP. Tank mixtures of Captafol + Kocide 101 and Delan + Copper oxychloride at half rates gave the best overall performance against CBD and increased yields significantly higher than the standard product Captafol 80 WP. Therefore, it is recommended to use these tank mixtures more frequently to control CBD
