Ugwuoke, KI | Onyeke, CC
The epidemiology of Bean Pod Mottle Virus (BPMV) disease of soybean involving screening of twenty soybean varieties and ten plant species for incidence of BPMV disease were studied for two years in the Nsukka Agro ecological Zone of Nigeria. Twenty soybean varieties used in the field experiments were laid out in Randomized Complete Block Design with three replications, while ten plant species used in Screen house experiments were laid out in Completely Randomized Design with three replications. Incidence of BPMV disease on soybean varieties by natural infection increased with time and reached 35% at 10 weeks after planting. The seed transmission of BPMV was not observed. Host range studies implicated five plant species including, Vigna unguiculata (L.) Walp, Glycine max (L.) Merril, Calapogonium sp., Desmodium sp. and Mucuna mucunoides. They served as alternate host of BPMV disease.
