How to Manage Pests

Pests in Gardens and Landscapes

Fusarium wilt on peas—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.
