Management of web blight (Thanatephorus cucumeris (Frank)) in common bean (Phaseolus vulgaris L.).
Several studies about web bligh control were carried out in Panama, the Dominican Republic, and Costa Rica. The pathogen´s genetic variability, bean varietal tolerance, chemical control, and sowing densities were evaluated. In Panama yield was increased through Benomyl applications and a greater sowing density. In the Dominican Republic Rhizoctonia AG 4, AG 2 2 and AG 1 groups were found. Several bean genotypes were evaluated, as well as populations from the web blight tolerant JB X MUS 14 cross. Between 20% and 40 % web blight severity was found in Costa Rica. Coverage and application of chemicals improved bean yield.
