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
