Fusarium Wilt Control
FUSARIUM WILT CONTROLFusarium wilt is a common vascular wilt fungal disease, exhibiting symptoms similar to Verticillium wilt. The pathogen that causes Fusarium wilt is Fusarium oxysporum . The species is further divided into forma specialis based on host plant. Disease fungi enter through the roots and interfere with the water conducting vessels of the plant.
|HOST PLANTS: Commonly found in tomatoes, tobacco, legumes, cucurbits, sweet potatoes and banana are a few
of the most susceptible plants, but it will also infect other
SYMPTOMS: As the infection spreads up into the stems and leaves it restricts water flow, causing the foliage to wilt and turn yellow. Symptoms often appear later in the growing season and are first noticed on the lower (older) leaves. As the disease progresses, the younger leaves will also be affected and the plant eventually dies. In many cases, only one branch or side of the plant show symptoms in what is referred to as the "yellow flag effect"
FAVORED ENVIRONMENT: Fusarium wilt can survive for years in the soil and is spread by water, insects and garden equipment. It develops during hot weather and is most destructive when soil temperatures approach 80 degrees F. Dry weather and low soil moisture encourage this plant disease.
FUSARIUM WILT CONTROL: Choose resistant varieties when available. Remove stricken growth and sterilize clippers (one part bleach to 4 parts water) between cuts. Control garden insects, such as cucumber beetles, which are known to spread the disease. Remove all weeds from the garden (many weed species host the disease). The biological fungicide Mycostop will control wilt caused by Fusarium. If the disease persists, it is best to remove the entire plant and solarize the soil* before planting again.
