July Questions
Q. What can I do to stop my
Crape Myrtle's leaves from turning black ?
A. The Crape Myrtle Aphid is
causing the leaves to get a black coating . Crape Myrtle Aphids are
small pale yellow insects that feed on plant sap. These insects secrete
a sugary substance called honeydew as they feed. The black coating that
you see is is called sooty mold. Sooty Mold forms on the honeydew
secretion not directly on the leaves. To stop the problem you can kill
the aphids with Insecticidal Soap, Ortho Systemic Insecticide, Hi-
Yield Malathion or SunSpray Ultra-fine Oil.
Q. What is causing my St.
Augustine grass lawn to yellow and die in patches that are in the
sun on good well drained soil?
A. The problem is likely
from the feeding activity of Chinch Bugs. Chinch Bugs are very small
insects that you are not likely to see without closely inspecting
the grass. Dig up a section of the declining grass and shake it hard
over a sheet of newspaper. If Chinch Bugs are present you should be able
to see them rapidly move about on the paper. You can also bring us a
sample of your lawn for inspection. To control Chinch Bugs we suggest
spraying with Acephate 75 and spreading Turf Ranger granules 2 weeks
later.
Q. What can I do to control
weeds in my lawn this Summer?
A. During the Summer heat
most lawn weed killers should be avoided to prevent injuring the grass.
The herbicide Image is an exception to this general rule. Image can
safely control a number of difficult weeds such as Dollarweed, Nutsedge,
Bahiagrass, and Dandelions in Bermuda, Centipede, St.Augustine and
Zoysia lawns. Bring us examples of the weeds that you would to like to
control to see if they are labeled. Several of the weeds that Image can
control will require repeat applications spaced 6 weeks apart.
