Oriental Fruit Moth and Permethrin
Every year my nectarine gets hit hard by oriental fruit moth. I spray with permethrin, and yet the next day I still see lots of OFM strikes. Is permethrin effective on these pests? Perhaps the concentration is too weak? I've been using Bonide 8 spray concentrate, which is 2.5% permethrin, mixed at 4 tablespoons (2 oz) per gallon, per instructions on the label. Is this just too weak? How do you control OFM?
