Blackberries & RedBerry Mite - Soybean Oil help
Hi, I have a great thornless black berry plant that produces a lot of large fruit. The past 2 years, i believe it's been infected with RedBerry Mites, and 50% of the crop is wasted. I want to control it this year.
I read that Golden Pest Spray Oil is a good oil to get, it seems really expensive though, and I'm not sure where to get it locally, so the shipping costs don't help.
I read that Golden Pest Spray Oil is 93% soybean oil and 7% inactive ingredients. What if I just buy soybean oil from the supermarket and use that diluted with water (although i don't know the proportion).
Any advice would be appreciated.
