Abstract
Verticillium wilt (caused by Verticillium dahliae Kleb.) is common and widespread in Washington State. Plant growth, yield, and verticillium wilt were evaluated for ‘Epic’ eggplant (Solanum melongena L.) grafted onto ‘Beaufort’ and S. aethiopicum L. rootstocks in two naturally infested fields and two greenhouse studies in 2010 and 2011. In the field, ‘Beaufort’-grafted eggplant had the greatest stem diameter and plant height in 2011, the lowest verticillium wilt severity in both years, and the highest marketable fruit weight in 2010 compared to non-, self-, and S. aethiopicum–grafted eggplants. In the greenhouse, when inoculated with V. dahliae, ‘Beaufort’-grafted eggplants had less wilting than S. aethiopicum–grafted eggplants, indicating that ‘Beaufort’ is the superior rootstock for disease management.
