Winter Temperature Index For Predicting Stewarts Wilt 2013

Temperature indexes averaging 106 to 113 combined degrees for December, January, and February, indicate that flea beetle populations could be high. If flea beetles are carrying the bacterium that causes Stewart’s wilt in corn, the disease could be a problem this year. Please see the report by clicking the link. Resistant varieties are available, as are controls for flea beetle populations. See the 2013 Delaware Commercial Vegetable Production Recommendations for control Suggestions.
