CIATs collection of promising bean lines was evaluated over a 2- mo period for resistance to web blight (Rhizoctonia microsclerotia) on a highly infested soil in Esparza, Costa Rica, where conditions are very favorable for the development of this disease. A scale of 1-5 was used, based on the per...

Several chemicals were tested at both the on-farm and exptl. levels to control major seed-transmitted root diseases in the Great Lakes region of Africa. Seed treatments to control the beanfly in Burundi were combined to assess the efficiency of combined treatments against fungi and insects. Indiv...

Best sources of resistance in the Great Lakes Region were evaluated for stability of resistance and multi-disease resistance at four locations in Burundi, Rwanda and Zaire. Some anthracnose, Angular leaf spot and sources were found resistant at all sites. Correlation analysis also suggest pathoge...

Although bean production in Latin America averaged 3.86 million/yr in 1968-71, literature on bean storage and storage losses in this regions is virtually nonexistent. Among the most important storage pests are Acanthoscelides obtectus and Zabrotes subfaciatus. These 2 especies are similar but dif...

In choosing an experimental design, emphasis should be placed on selecting one that minimizes experimental error variance. A comparison is made of the randomized complete block and lattice designs, giving the advantages and disadvantages of each. It was found that the lattice design was much bett...

Results of a survey of 159 farmers in southern Costa Rica indicate that the new bean varieties Talamanca and Brunca are widely adopted. This report analyzes the factors determining their success. The role played by seed availability is considered. Farmers evaluated these varieties in terms of yie...
