Legumes - Diseases

Peas/Cowpeas | 14-20 fl. oz. per acre. REI: 12-hour. PHI: 21day.
FRAC 07.
Viruses of Multiple Crops - Multiple
Pathogens
Bean Yellow Mosaic Virus (BYMV) overwinters in wild
legumes, like sweet clover, and is spread by aphids.
Non-Pesticide
Beans (Dry), Beans (Fresh), Lima Beans | For BYMV: Keep
new plantings as far as possible with the previous production
area. Eliminating overwintering host plants such as wild
sweet clover may reduce infection. Monitor for aphids and
avoid broad-spectrum insecticides that might kill natural
enemies and flare aphid populations. Some tolerant varieties
are available. Prompt destruction of the finished crop with
tillage to rapidly breakdown tissue is an important method to
prevent disease build-up and transfer back to overwintering
wild legumes.
Pesticide
Insecticides Beans (Dry), Beans (Fresh), Lima Beans | For
BYMV: use aphid-specific insecticides to lower the
population without also reducing the population of natural
enemies. See insect section.
White Mold (Timber Rot, Drop, Stem
Rot) of Multiple Crops - Sclerotinia
Fungus
This soil pathogen is long-lived in the soil, and has a wide
host range on broadleaved crops and weeds, including beans,
vine crops, lettuce, tomatoes, peppers, and cole crops. It goes
by other names in other crops, such as Drop, White Mold,
Stem Rot, and Timber Rot.
It is more commonly where humidity and temperatures are
high. The fungus often infects flowers, which then drop off
and infect the stems that they land on. The stems take on a
woody appearance and can split open. Inspection of the stems
will reveal small black pellets that are the overwintering body
of the pathogen.
Non-Pesticide
Beans (Dry), Beans (Fresh), Southern Peas/Cowpeas | Avoid
fields with a history of the problem. Rotate to a non-broadleaf
crop, such as grass grains or sweet corn for >6 years. Prompt
destruction of the finished crop with tillage to rapidly
breakdown tissue is an important method to prevent disease
build-up.
