Halo blight of bean is a bacterial disease caused by Pseudomonas syringae pv. phaseolicola. Halo blight’s pathogen is a gram-negative, aerobic, polar-flagellated and non-spore forming bacteria. This bacterial disease was first discovered in the early 1920s, and rapidly became the major disease of beans throughout the world.
Phaseolus coccineus, known as runner bean, [2] scarlet runner bean, [2] or multiflora bean, [2] is a plant in the legume family, Fabaceae. Another common name is butter bean , [ 3 ] [ 4 ] [ 5 ] which, however, can also refer to the lima bean , a different species.

Bacterial wilt is a disease of the vascular tissue. When a plant is infected, E. tracheiphila multiplies within the xylem , eventually causing mechanical blockage of the water transport system. The first sign of infection, which appears about five days after acquisition, is the wilting of individual leaves on a single stem.
Leaf scorch (also called leaf burn, leaf wilt, and sun scorch) is a browning of plant tissues, including leaf margins and tips, and yellowing or darkening of veins which may lead to eventual wilting and abscission of the leaf.
Colletotrichum lindemuthianum is a fungus which causes anthracnose, or black spot disease, of the common bean plant (Phaseolus vulgaris).It is considered a hemibiotrophic pathogen because it spends part of its infection cycle as a biotroph, living off of the host but not harming it, and the other part as a necrotroph, killing and obtaining nutrients from the host tissues.
Curly top of common bean caused by Beet curly top virus. Curly top [1] is a viral disease that affects many crops. This disease causes plants to become smaller in size, have shriveled petals and leaves, and are twisted and pulled out of shape.
Bean leaf beetle abundance increased with the increase of soybean production in the 20th century, but their spread northward was prevented by the inhospitality of northern climates. [ 3 ] The availability of soybean is the primary constraint for the beetles, so the beetles can’t live in an area that doesn’t have soybeans. [ 3 ]
