Arugula, a high value crop for organic growers in the Puget Sound region, has a low tolerance for damage, especially cosmetic damage caused by foraging adult flea beetles. Beetle control options for organic growers are typically broad-spectrum, making them less desirable than encouraging natural enemies. Andrew Stout of Full Circle Farm, which grows 50 different crops for wholesale and direct markets, plans to test three treatments for controlling flea beetles. The first is a trap crop called Green Wave Mustard, which research has shown to be an effective trap for flea beetles. The second, a commercial garlic spray used as a repellent, will be applied directly to the arugula plants. And Surround WP, a kaolin clay product that acts as a physical deterrent to foraging, will be applied. For comparison, one plot will remain untreated.
