Issue no. 6 of the Home, Yard & Garden Newsletter is now available
IN THIS ISSUE:
=================================
Kermes scales are occasionally found on pin, white, bur,
and other oaks in Illinois. They are most common on or near the branch tips and
appear gall-like, so they are commonly misidentified as galls. They also tend
to feed in leaf axils, so they are sometimes misidentified as buds.
---------------------------------------------------------------
Aphids are more noticeable this spring, particularly on
linden and tulip poplar, than they have been for many years. Since the late
1990's when multicolored Asian lady beetles became numerous in the state, aphid
numbers have tended to be low.
---------------------------------------------------------------
Japanese beetle adults have emerged in Kentucky, so be
watchful for emergence in southern Illinois. We continue to see insect
emergence about two weeks ahead of schedule throughout Illinois. With emergence
in southern Illinois typically occurring around the middle of June, emergence
is likely around the end of May.
---------------------------------------------------------------
Hosta virus X (HVX) is a pathogen that has plagued
gardeners worldwide. As with most
viruses, HVX will not kill hosta; however it can cause a number of undesirable
symptoms to appear on the host. HVX is also a difficult virus to pin down
because symptoms can often take years to appear in infected hosts, and in some
cases no symptoms may ever appear.
---------------------------------------------------------------
After an abnormally warm, dry spring in Illinois,
anthracnose might still be rearing its head. Anthracnose is a disease caused by
a variety of fungi, all morphologically similar and with similar symptoms: tan
to brown or black lesions on the leaves, stems, flowers, and fruits of various
plants. Anthracnose infections occur during rainy, spring weather, and usually
subside by mid-summer.
---------------------------------------------------------------
I've had a few queries about catchweed bedstraw lately.
Galium aparine is an annual weed that has been quite prevalent this
spring. It has a semi-prostrate habit
and is commonly found in shaded or wooded areas climbing up over the top of
surrounding vegetation. It is primarily found in landscapes, nurseries, small
grains, and meadows.
