Symptoms caused by Alfalfa mosaic virus (AMV) are patterns of bright yellow and dark green leaf tissue. Newly emerged leaves may be small with bright yellow spots and brown discoloration and plants may be stunted. Alfalfa mosaic is transmitted by more than 15 aphid species, including the soybean aphid. Alternate hosts of AMV include alfalfa, other legumes, and solanaceous... Read More
Anthracnose stem blight is generally a late season disease prevalent on maturing soybeans. Irregularly shaped red to dark brown blotches on stems and petioles can appear during early reproductive stages. Petiole infection can result in a shepherd's crook (curling or "hooking" of plant tissue). Near matur... Read More
Bacterial blight is usually one of the first foliar diseases to occur on soybean. Bacterial blight seldom causes serious yield loss. Symptoms usually begin in the upper canopy because young leaves are most susceptible. Small, angular, reddish-brown lesions are surrounded by a yellow halo. As the disease progresses, l... Read More
Bacterial pustule occurs mid- to late season when temperatures are warmer. Lesions are found on outer leaves in the mid- to upper canopy. Lesions start as small, pale green specks with elevated centers and develop into large, irregularly shaped infected areas. A greenish-yellow halo surrounds each lesion. A... Read More
Foliar symptoms caused by Bean pod mottle virus (BPMV) include distorted and wrinkled leaves that have a mottled color pattern. Symptoms appear more severe on young leaves, sometimes with a raised, blistered, or distorted appearance. Symptoms are most obvious at cooler temperatures and often disappear when it is hot. Infection by BPMV decreases pod formation, reduces see... Read More
