Several uses have recently been added for Tolfenpyrad, the active ingredient in Torac, a group 21A insecticide/group 39 fungicide. It has efficacy on thrips, aphids, several leps, and Colorado potato beetle. It is also labeled for powdery mildew. Torac is contact only. Crop sites and a few of the interesting pests that have been added are potatoes (potato beetle, leafhopper, aphids, thrips, psyllids), brassica leafy greens (aphids, flea beetles, thrips, maggots, diamond back moth), fruiting vegetables (aphids, thrips), and cucurbits (aphids, thrips, powdery mildew). The label also lists cucumber beetle as suppressive only. Supplemental labels can be found for the following
