Symptomatology of Phytophthora canker of cacao following river flooding
Cocoa plantations on the banks of the River Doce and River Sao Mateus in the State of Espirito Santo and River Jequitinhonha in south Bahia were flooded for many weeks after abnormally heavy rains in the hinterland of southeast Brazil between late 1978 and early 1979. Immediate loss of trees was attributed to physiological effects of inundation and physical damage by uprooting. However in late May 1979, as the rivers were subsiding, investigation into reports of tree mortality showed a severe outbreak of canker on the affected trees caused by Phythophthora palmivora. Certain symptoms of the disease hitherto not reported, are now documented
