Cassava root rot disease is an increasing problem in Africa where yield losses of about 80% have been recorded. We evaluated 290 African landraces and 306 improved genotypes from the germplasm collections of the International Institute of Tropical Agriculture (IITA), for sources of resistance usi...

The burrowing nematode, Radopholus similis, is a serious threat to sustainable banana production worldwide. A promising way of controlling nematodes is through the development and deployment of resistant cultivars. This usually involves crossing triploid cultivars with fertile diploids to produce...

Resistance of 360 var. of Phaseolus vulgaris to Empoasca kraemeri was evaluated in the greenhouse. Subsequent field evaluations were made of 30 promising var. when 30 days old. Seedlings in the greenhouse were infested with field-collected adults for 3 days, and resistance to 1st generation nymph...

Disease progress of angular leaf spot caused by Isariopsis griseola Sacc. was determined in the field on 14 bean cultivars after artificially induced infection. Isolate IG1-77 of the fungus was used to cause the infection, and evaluation was made using the CIAT disease severity scale of 1-5. The ...

Soybean rust, caused by Phakopsora pachyrhizi Syd., is a major disease limiting soybean [Glycine max (L.) Merr.] production in many areas of the world. Yield losses of up to 80% have been reported in experimental plots in Taiwan. Although the disease is not always yield limiting, it has the poten...

A survey of BCMV in 6 municipalities of western Antioquia, Colombia, confirmed an epidemic in this region. However, planting with virus-free seed and the eradication of BCMV-infected plants during the first 30-40 days after planting were not effective in controlling the disease. Three BCMV-resist...
