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.
