I've got some boxwoods I have to protect from miner bugs every spring, and right about now is time to do the annual insecticide drench, and lo and behold the stuff has doubled in price just like everything else. I'll include a pic of what I've used up til now. It used to be a concentrate that you watered down and applied, but now the new and improved version is undiluted and very $$. The main ingredient is 1.47% imidacloprid after it's diluted.
Any suggestions for a cheaper insecticide alternative with the same active ingredient?
Thanks!
