any one have good results with a particular product for the riding of sooty mold ?
Could you tell me what it is.
black sootlike mold on crape myrtles
Thanks for the reply but i only do installs and no maintance.
sooty mold is caused by Aphids on the under side of the leaf, they climb to the top of the leaf to use the "bathroom" and leave this blackness on the top of the leaf. aphids are very small bright green oval shaped bugs-smaller than a baby ant. after the aphids are killed, you can spray the soot with liquid ivory soap in a hose end sprayer, let it sit a few mins and wash it off with water. repeat if needed.
thank you for the help. what is best to kill them ?
not sure as i dont spray anymore but the label on the pesticide will say if you can use it on aphids.
horticulture oil will kill the pest and loosen the mold
but, you can't spray oil this time of year, can you?
yes there is a light or summer oil
