In some cases, bacteria, fungus, and fungal pathogens, as well as mildew, extreme humidity, and overcrowding has also been known to trigger bud blight. In soybeans, this disease can actually reduce crop production by 25-100%, depending on the severity of the infection.

Unlike powdery mildew, which is caused by a fungal pathogen, bud blight can be caused by either a fungus or a bacterium. Even plants weakened by a pest infestation can begin to develop bud blight.

In young plants, this disease can be characterized by stunted growth. Adult plants may start to bend over and wither while buds can fall off or turn brown. Leaflets tend to be on the smaller side and cupping may cause them to deform.

As far as the pods of the plant are concerned, they tend to abort, develop poorly, or have brown patches. Bud blight has also been known to create delayed maturity in some plants.

To manage this disease, it is important to avoid planting other plants next to the affected crops, for starters, as well as prevent the outbreak from occurring in the first place by sanitizing equipment and keeping a tidy growroom that has air-quality controls in place.
