Intensity of dry rot disease of yam in the State of Alagoas, Brazil.

Intensity of dry rot disease of yam in the State of Alagoas, Brazil.

The objective of this study was to conduct a survey on the presence of phytonematodes associated with dry rot disease, to be able to quantify and identify the species being damaged, and to evaluate the disease incidence in the main yam-growing areas in the state of Alagoas, Brazil. Altogether, 39 samples of yam tuber were collected. High population densities of the plant parasitic nematodes Scutellonema bradys, Pratylenchus coffeae and/or P. brachyurus were associated with the decay of the yam tubers. The disease was found to be widespread throughout the production areas. The disease incidence ranged between 0.2 and 85%.
