> * If youre growing poinsettias, plant pathologist Gary Moorman at
> Penn State Univ. suggests starting to scout for powdery mildew in
> early
> to mid-Sept. If you wait, foliage and bracts could be permanently
> scarred since powdery mildew doesnt go away. Look at the top and
> bottom of the 4 most mature leaves on 1 out of every 30 plants. If
> powdery mildew is found, re-examine 1 out of every 10 plants. Remove
> infected leaves by cutting the petiole and gently placing them in a
> plastic bag, which should be closed immediately after inserting a
> leaf.
> After removing infected leaves, Moorman suggests spraying plants
> every 2 weeks with Strike at 4 oz./100 gal. Dont add spreader
> stickers.
> Continue to scout and discard infected leaves. Error! Bookmark not
