Bean anthracnose, caused by the fungus Colletotrichum lindemuthianum, is a worldwide disease in susceptible var. grown in locations with cool to moderate temp. and with a high RH. It can appear anywhere in the plant. Losses can be up to 100 percent when severely infected seed is planted. For effi...

The Great Lakes Regional Bean Program works with the agricultural research institutions of Burundi, Rwanda, and Zaire. Advanced breeding lines were introduced as potential new var. for the region and/or as sources of resistance to angular leaf spot, anthracnose, Ascochyta leaf spot, halo and BCMV...

In 1984, most of the pathology efforts of the CIAT Bean Program concentrated on the evaluation of bean germplasm for their reaction to the main bean pathogens under field conditions in several international nurseries throughout many of the bean growing areas. High priority was given to the most w...
