I do not know if you have seen ogbiowar before Lion but, the stuff is amazing. I brew a tea once a week and
have not fought a single thing since. It's pretty cheap and 24 hours after feed you will see noticeable difference
in overall health.
You can use the foliar pack as a drench to take care of fungus gnats, grubs, ra, and nematodes. If you just use
just the root pack and you will have a good D. against all pests and pathogens including pythium, fusarium and PM.
