Lygus lineolaris (Palisot de Beauvois) was the major plant bug species causing apical seediness in strawberries in experimental plantings. Counts indicated that 1 nymph per inflorescence resulted in 20-30% injured berries when harvested 3 weeks later. Of various programs investigated, dimethoate appeared to offer the greatest potential for reduction of plant bug injury. A suggested program includes dimethoate, 0.5 lb active ingredient per acre, at early blossom followed by malathion or trichlorfon, 1.0 lb AI/acre, applied 14 days later.
