I've got White scale on my Magnolia tree and just used Bayer's Systemic Tree and Shrub on it . I'm worried ...

Question

Has anyone used it with success ?

Answer 1

Bayer's Systemic Tree & Shrub Care product is very safe and will not harm your magnolia tree. I've used it on just about every plant around my home and have never seen any problems.

It's very safe and does an excellent job controlling most sucking insects (except mites). If you followed recommended rates on the label and watered the product into the soil around the roots, you should begin to see results withing 2 weeks or so. The product is systemic and protects most trees and shrubs for a year or longer.

However, if you wish to obtain quicker results in eradicating your scale insects, you might want to consider using some "Safer's Soap" or "Ultra-Fine Horticultural Oil". Just remember NOT to apply during hot weather when applying either of those products.

Answer 2

Bayer is a chemical called Imidacloprid, it will be good for next year, because it is a systemic and the growing season is coming to a close.
That means that it will be slow going through the trees circulatory system . So for next year you are protected.
For this year, get out the old fashioned horticultural spray for contact kill. But maybe wait until the middle of next month for the Right BUGGIE growth stage for the oil to hit and kill at its best potential.
All of that is a knock down until the Bayer has a Chance to take effect!

Answer 3

the bayer's product will work, but it won't get rid of the problem automatically. to kill the white scale now, spray Bug Buster on it. if the chain stores don't have bug buster, try your local professional nursery. oh, and the bayer's product will prevent the scale from coming back. :)

Answer 4

just to add to jazzmans advice, don't spray during the hot part of the day. wait until after 4.

Answer 5

Scale is an insect. Does your insecticide kill scale?
