Bean
Pod Mottle Virus is transmitted by bean leaf beetles. The disease can cause
reductions in soybean yield and seed quality. Some symptoms of the disease
include a blistered appearance to soybean leaves, green stems at the end of the
season when pods are mature, and a mottled appearance (bleeding hilum) on the
seed coat of harvested soybean. The only way to confirm that a plant is infected
with bean pod mottle virus is to have plant tissue tested. If bean pod mottle
virus has not been present in your fields, i.e., no green stem at harvest or
seeds with bleeding hylums then the only reason to consider early-season bean
leaf beetle management is if populations reach extremely high levels (more than
2.5 beetles per plant).
