Cultural characteristics and biochemical reactions of isolates of Crinipellis perniciosa, causative agent of witches' broom disease of cocoa



Cultural characteristics and biochemical reactions of isolates of Crinipellis perniciosa, causative agent of witches' broom disease of cocoa



Proceedings of the Tenth International Cocoa Research Conference, Santo Domingo, Dominican Re ic, 17-23 May 1987: 363-366



Dry vegetative brooms were collected from commercial farms in 12 localities in Brazil and also from other hosts in the Amazon region. Basidiocarps produced by these brooms were used to form mycelial cultures for studies of growth-rates, compatibility studies and biochemical reactions. The isolates were classified into 4 groups: Group 1-Cocoal and Castanhal; Group 2-Ouro Preto D'Oeste and Jaru; Group 3-Cameta; and Group 4-the remainder.
