This product is being used as a systemic - It was applied to the ground surrounding the affected trees. Will probably take 5-6 weeks to determine if it has taken care of the white fly issue. Would have appreciated more feedback on whether others feel this product works on white fly infestations.
The Adonis 2F product didn't kill the white flies but did control them a lot better than the store bought products. I did find that for residential use its a little hard to break down the chemical to water ratio 1.5oz to 100gal of water.
