Evergreen 60-6 for ROOT APHIDS

This is for a drain to waste coco setup. Not recirc hydro...

Has anyone used Evergreen 60-6. Have used Pyganic, but was hoping to use Evergreen and have less root damage from the oils, as it is a stronger pyrethrin concentrate.

I see people saying 2/ml per gallon. Has anyone gone stronger??

Thinking about trying 5ml/gallon.

I was doing 40/ml gallon of pyganic ec 1.4... to get the same amount of pyrethrin from the Evergreen as pyganic at 40ml/gallon... the dosage of evergreen would be 9 ml/gallon.

So what is the highest ml/gallon you have used evergreen as a soil drench. Anyone go out to 9ml/gallon?

I think that Evergreen uses a higher ratio of Piperynol Butoxide... so the pyrethrin could be more effective with less.

Damn, should have just got the pyganic. At least I know what strength to apply and how long it will be effective.
