Fusarium wilt—Fusarium oxysporum f. sp. pisi
Plants infected with Fusarium wilt show a yellowing of leaves and stunted growth. A cross-section of
the lower part of the stem may show reddish orange discoloration. Eventually the whole plant becomes affected.
Fusarium wilt is caused by a soilborne fungus.
Wilt diseases can be avoided in many cases by planting resistant
or tolerant varieties. When growing susceptible plants, problems
sometimes can be minimized by rotating crops, following
good sanitation practices, and using soil
solarization. Pull up and destroy
infected plants as soon as you notice them. Do not replant
peas in the soil for 5 to 10 years unless resistant cultivars
or solarization are used.
