Control of flea beetle in cole crops with cruciferous trap crops

Objectives: To evaluate a wide variety of potential trap crops for use in cole crop production. To test various configurations of trap crop plantings in production fields to test the potential for reducing damage by flea beetles to crops. To evaluate the economics of utilizing trap crops against flea beetles. 
Stated 
Methods: Nine trials were established examining various aspects of utilizing trap crops to attract flea beetles. Each was evaluated by vacuuming the trap crop and counting the number of flea beetles from a predetermined length of row. Trap crops tested included; Trials 1-2) mustards (southern giant, red giant, green wave) and white mustards (martigena and wieber); 3-4) Green wave mustard in market crops of arugula, mizuna and tatsoi; 5-6) mizuna and green wave mustard in broccoli; 7) green wave mustard in cabbage; 8) green wave mustard in cabbage; 9)screening trial of mustards canola, tatsoii, mizuna, kale, radishes ,white lady turnip, chinese cabbage and pak choi. A flea beetle control trial was established, testing the efficacy of Plant Wash, Trilogy 90 and Pyrellin EC.
