Web blight, caused by the fungus Thanatephorus cucumeris, is prevalent in tropical regions with high to moderate temp and RH; more than 200 plant species serve as hosts to this pathogen. Hyphae can grow rapidly over healthy tissue of leaves, flowers, petioles and pods. For efficient control, the ...

La mancha hilachosa, causada por el hongo Thanatephorus cucumeris, prevalece en las regiones tropicales con una temp y humedad relativa entre moderada y alta; mas de 200 especies vegetales le sirven de hospedante al patogeno. Las hifas del hongo pueden crecer rapidamente sobre el tejido sano de l...

The number and weight of seeds produced per plant were significantly (P = 0.01) reduced, 47.5 and 56.3%, respectively, in Diacol-Calima bean (Phaseolus vulgaris) plants infected with bean southern mosaic virus (BSMV). The number of pods per plant, on the contrary, was often higher in systemically...

One necrosis-inducing strain and four mosaic-inducing strains of bean common mosaic virus (BCMV) were differentially seed-transmitted in 14 mosaic-susceptible bean (Phaseolus vulgaris) cultivars. Dubbele Witte, Redlands Greenleaf B, Michelite, Sanilac, and Red Mexican 35 consistently transmitted ...

Bean germplasm was evaluated at CIAT for resistance to BCMV strains NL-4, NL-3, and NL-5 in order to use them in the national breeding and selection programs in Africa, Europe, USA, and Chile. Ninety-eight lines were selected for an international Bean Common Mosaic/Black Root resistance nursery. ...

Thirty-nine Brazilian bean var. were evaluated for their resistance to problem X originated in the soil and detected in Colombia. Eleven materials previously evaluated were used as controls. The plants, grown in pots with soil collected at the places where the problem is common, were evaluated 20...

Three comoviruses isolated from diseased bean plants in Brazil (CV-BZ), Venezuela (CV-VZ), and Honduras (CV-HD) were inoculated to 53 bean genotypes possessing or lacking the dominant alleles of the necrosis (I) gene, which conditions resistance to bean common mosaic virus (BCMV). These comovirus...

Bean dwarf mosaic virus (BDMV) was transmitted mechanically and by the whitefly Bemisia tabaci from and to susceptible bean (Phaseolus vulgaris) cultivars. Two species of Sida, suspected weed reservoirs of BDMV, were also shown to be susceptible hosts by whitefly transmission tests. Electron micr...
