I'm thinking about a neem spray to keep SWD and cane borers off my berries in conjunction with better cultural practices (timely harvest and cane removal)I lost 1/3 of the crop to SWD last year and borers have killed 1/2 my canes that should be bearing this year. I know ingestion is required for neem to work generationally that might help with SWD larva, but there is a repellant aspect as well for borers similar to apple tree borers. However, I can't apply a concentration over 5% to keep from burning the leaves. Is this the best route? I don't know if I can stomach even organic broad spectrum insecticides, but what are some other options out there?
