Which one would u guys recommend I'm in coco in veg wanting to use once then follow up with ogbiowar. Was thinking 5ml per gal of the bayer. What u guys think?
I honestly wouldn't use imidacloprid on a non-ornamental plant. If you look there are warnings about it on the bottle. The stuff is systemic, which means it works by building up inside the plant. I would use a neem extract like Azamax or something with pyrethrin(Bonide makes a product that is both cheap and available at a lot of hardware stores).
Fruit and veg works well. Don't use the shrub and tree unless u want added fertilizers. If u are in flower it may be to late unless u are really early. If u are in veg then it usually takes about 10-14 days to get rid of the little bastards. I hate root aphids about 4 or 5 years ago and the only thing that I found that worked on them was imidacloprid products. I would not make a habit of using it as a proactive preventative but if u are in veg and u have root aphids it will work on them.
Once u get rid of them check any new clones u bring in the garden. That's usually how they get in there..
