Green
Flag for Grub Control Applications!!
If you
have been anticipating the go-ahead for grub control applications
in your lawn, now is the time to 'let 'er fly.' Keep in mind
that this go ahead is only for the application of preventative grub
control products. These include imidacloprid (Merit) and halofenozide
(GrubX or Mach 2). Both products are very long lasting but must be
applied as preventative treatments, before the grubs hatch. They may
be applied anytime from now until the first week of August for best
results. As with all homeowner-applied insecticides, it is critical
to follow the label directions exactly when making applications.
On
the other hand, recent studies at Cornell University have shown
that over 70 percent of all grub control treatments were applied
needlessly. Why? Because there were no grubs in the lawn to treat
in the first place. I am sure that this is equally true in Indiana.
Many homeowners are frightened into applying grub controls because
of advertisements on TV, in plant centers, or because of horror
stories they have heard about grub damage. The truth is that the
'just-in-case’ philosophy of applying grub controls is
not only expensive but hard to justify from an environmental standpoint
unless grubs were present in that area in the past.

To Mow or Not To Mow? That's a good question
Summer
has definitely arrived, and this year's wet spring is a mere memory.
While the main challenge this spring was to mow often enough to
keep up with the flush of growth, now most areas across the state
are drying up and turf growth has slowed. During the dry, hot summer
days, mowing can be a significant stress on cool season turf (Kentucky
bluegrass, perennial ryegrass, tall fescue etc.).

Brown Rot of Stone
Fruits
Brown rot of cherry is caused by the fungus,
Monilinia fructicola. Other stone fruits such as apricot,
peach, nectarine, and plum are also susceptible. Although symptoms
first appear during bloom, the most noticeable symptom is rotting
fruit with light brown tufts of fungal spores. Diseased fruit fall
to the ground or remain attached to the tree as mummies (dried shriveled
fruit). The disease is most damaging when wet weather occurs during
bloom and during the fruit-ripening period.
