Aphid/Virus
Aphids are pests to pea, lentil, alfalfa and clover. They survive by sucking sap from stems, leaves and pods which in turn deplete the plants resources required to set and fill seeds. Aphids can be easily detected in a field by inspecting plants. A mature pea aphid is small-approximately 1/8+ inch long and range from pale to dark green in color. They move slowly and do not hop.
Scouting for pea aphids
Aphid populations should be assessed during bloom to determine if potential yield loss is greater than the cost of control measures. Aphid populations can be evaluated by counting the number of aphids on the top eight inches of at least 20 plants sampled throughout the field or with a sweep net. If there are more than four aphids per plant or 15 aphids per sweep, a treatment is advised shortly after bloom.
