Black pod disease caused by P. palmivora and P. megakarya in Ghana is one of the major
causes of yield loss in cocoa. Several defense mechanisms are required to counter attack …

Black pod disease caused by Phytophthora palmivora and Phytophthora megakarya is a
serious constraint to cocoa (Theobroma cacao L.) yields in Ghana. To investigate the …

Twelve diverse cacao (Theobroma cacao) genotypes were assessed for pod resistance to
Phytophthora palmivora at the penetration and post‐penetration stages of infection using …

Black pod caused by Phytophthora species is a devastating disease of cacao (Theobroma
cacao L.) in production regions worldwide. Breeding for cacao genotypes resistant to black …

Phytophthora megakarya (Pmeg) and Phytophthora palmivora (Ppal) cause black pod rot of

Phytophthora pod rot (Ppr) disease caused by Phytophthora megakarya is the major
constraint to cocoa production in Cameroon. The development of resistant varieties requires …

Abstract In 1988, the Paper Disc Method was developed at CATIE to evaluate resistance to
Phytophthora palmivora in cocoa [Theobroma cacao]. This simple and efficient method …

In this study a leaf inoculation method was used to standardize a bioassay for testing the
genetic susceptibility (or resistance) of cocoa cultivars to black pod disease caused by …

The Phytophthora pod rot disease constitutes a major threat to cocoa cultivation in all cocoa-
growing regions worldwide. It is one of the most important diseases limiting the attainment of …

Pod husk thickness and percentage moisture content were evaluated for their influence on
