Development of effective management tools for Fusarium wilt on lettuce


Fusarium wilt of lettuce was first found in Arizona in 2001. Since that time, the disease has been detected in additional fields every year. The goal of this research is to study the biology and ecology of disease development in order to facilitate development of effective management strategies to minimize crop losses due to Fusarium wilt. Initial research has shown that disease severity is dramatically reduced in infested fields when the crop is seeded in late November and December compared to planting in September and October. Furthermore, romaine lettuce has been found to be more tolerant to Fusarium wilt than iceberg lettuce. Studies are currently in progress to evaluate soil solarization as a potential disease management tool.
