This Pest Risk Analysis (PRA) documents outlines risks associated with the movement of grain and seeds of beans, Phaseolus vulgalis L. within East African member countries namely: Kenya, Burundi, Rwanda, Tanzania and Uganda.

A list of pests associated with beans in East Africa was developed based on the Pest Risk Analysis (PRA) information from the East Africa NPPOs as well as from the search of both print and electronic sources of information, in accordance with ISPM No. 11 and 21. Based on the analysis, a total of 184 pest (63 insect, 5 mite, 67 fungi, 20 nematode, 17 bacteria and 12 virus) were found to be associated with seed and grain of beans. Out of this 9 pests comprising of one (1) insect (Callosobruchus analis (Fabricius) (bean weevil), one (1) nematode (Ditylenchus dipsaci (Kühn,) Filip'ev stem, and bulb nematode), five (5) fungi (Sclerotinia sclerotiorum (Lib) de Bary Cottony soft rot, Fusarium oxysporium fsp phaseoli, Fusarium solani fsp phaseoli, Choanephora cucurbitarum (Choanephora rot) and Elsinoe phaseoli (Bean scab), one (1) bacteria (Pseudomonas syringae pv. syringae van Hall 1902 Bacterial brown spot (beans) and one (1) virus (Cucumber Mosaic Virus), were classified as quarantine pests requiring phytosanitary measures/actions for bean seed. However, all of these pests were found to have negligible overall risk in bean grain except for Callosobruchus analis (bean weevil) which was found to have high risk.
