ABSTRACT Data collected in 2002 and 2003 on Alfalfa mosaic virus and Cucumber mosaic virus incidences of infection in commercial snap bean fields in New York State were used to develop relationships between disease incidence (p(low)) and sample size while accounting for the inherent spatial aggregation of infected plants observed with these two viruses. For a plan consisting of 300 sampled plan...
in this research, first eighty five percent of broad bean stover mixed with nine percent of wheat straw and six percent of sugar beet molasses ensiled and its digestibility determined by four mature weathers. in the next stage, broad bean stover silage (bbss) included in the ration of twenty male lambs with average body weight of 25.53±2.23 kg for 84 days in a completely randomized design. fora...
In Iowa, the management of insect pests in soybean, Glycine max (L.) Merr., has been complicated by the arrival of the invasive species soybean aphid, Aphis glycines Matsumura (Hemiptera: Aphididae), and occasional outbreaks of bean leaf beetle, Cerotoma trifurcata (Förster) (Coleoptera: Chrysomelidae), populations leading to economic losses. Several insecticide programs designed to reduce abun...
The recent identification of a new nanovirus, pea necrotic yellow dwarf virus, from pea in Germany prompted us to survey wild and cultivated legumes for nanovirus infections in several European countries. This led to the identification of two new nanoviruses: black medic leaf roll virus (BMLRV) and pea yellow stunt virus (PYSV), each considered a putative new species. The complete genomes of a ...
