CLOSED: A less of a bio-hazard for whiteflies n aphid control?

Xeramtheum Summerville, SC(Zone 8a) Sep 12, 2008

I started an experiment last spring without me knowing it. I wanted to see how readily mature Confederate Rose crowns would transplant and if they'd resent being moved, so I dug up one early, just as I started to see green and plopped it in a large planter. It grew with no problems so later this spring, I moved another CR to a different place in my garden and stuck it in the ground.

In comparing the two, the one in the ground acquired aphids and whiteflies by June. The one in the container has none!!! What this is telling me is that if you can stop the aphids getting onto the plant (they obviously climb on) the whiteflies won't come. So the trick seems to be, put a barrier around plants in the ground. I'm thinking something like Tanglefoot .. I wonder if Diatomacious earth might also be a good deterrent.

diatomacous earth is a good thing but in my experience, whitefly are not drawn by aphids and you can have one without the other. i also don't believe that barriers will stop aphids.
