Leafminers are fly larvae that tunnel between leaf layers, creating winding white trails. Heavy infestations cause leaves to drop. Control: remove and destroy affected leaves, fertilize to encourage new growth, and apply spinosad (an organic insecticide) weekly for the first six weeks after planting next season.
