Japanese Beetles: They’re Back!
The first Japanese beetles of the year were observed in central Indiana last week and now is a great time to review the biology and control of these pests. Japanese beetle adults pupate from larvae in late spring and begin emerging at this time of the year. We expect them to arrive in full force […]
More on Nematodes and Indiana Greens
As our nematode survey continues, more questions are being asked about nematodes, their damage potential, etc. Following is an update on the survey: Do not attribute all vague symptoms to nematodes. Nematode populations and symptoms are extremely complex and cannot be diagnosed by anyone other than a nematologist. In other words, don’t panic. […]
Finding Spring Grubs?
Each spring we receive many calls about grubs as people find them while planting gardens or ornamental beds. These are often large and appear menacing however do not let their appearance cause you to worry, panic or run out to buy an insecticide to annihilate these sinister creatures. These grubs are not feeding actively so […]
Nematode Damage in Golf Greens
We are suspecting more and more instances of actual nematode damage or at least secondary effects of nematodes in golf greens. Effects of nematode feeding would include yellowing, thinning, enhanced drought stress, and other symptoms reflective of a poor root system. Unfortunately, symptom expression may be enhanced or complicated by poor rooting from summer weather, […]
First Black Cutworms of the Year Found in Traps
Recent storms have generated the weather patterns that bring black cutworm moths into our state each year. Pheromone traps picked up the first black cutworm moths of the season during the past two weeks. Predictive models estimate that the first cutworm caterpillars will begin feeding 300 heat units after the first moths are caught. Unseasonably […]
Japanese Beetles are in Full Force
The first Japanese beetles of the year were observed in central Indiana on June 22 and have since come out in full force. They are being reported in large numbers from many places throughout the state feeding on their favorite plants. Plants particularly at risk include those that have been recently transplanted or those that […]
Update on Black Cutworm
Significant weather events from the south usually are responsible for the movement of the black cutworm moths into our area each spring beginning as early as March. Black light traps stationed throughout the state have failed to catch many black cutworms this year to date. This is good news for our industry and may spell […]
Control Them Now
Now is a very good time to spend a little extra effort in controlling those pesky moles. Recent warm, wet weather has returned these nasty little turfgrass destroyers back to the surface of the soil where they are making runs throughout the turfgrass. March and April are ideal times to control moles because this is […]
Mid-winter Mole Activity
Mole activity is becoming more apparent with the recent warm weather. Large piles of soil on the lawn surface are evidence of the moles subterranean mining. Unfortunately control of this pest still depends on trapping or possibly a mole-hunting cat or dog. Techniques such as drowning with water, poisoning with car exhaust, shocking or vibrating […]
News about Japanese beetles is mostly bad!
Japanese beetles are back! They appeared 10 days to 2 weeks earlier than normal this year and indications are pointing to a very heavy population in many parts of the state. Last years weather conditions kept soils moist which apparently led to a very successful grub hatch. Early emergence usually points to a somewhat earlier […]
Bumpy Lawn?
Lawn seem bumpier this spring when you first mowed it? Bumpy, difficult-to-mow lawns can be caused by either above-ground factors or below-ground soil factors. If the bumpiness is due to patches of incompatible species of coarse, bunch grasses like tall fescue or orchardgrass growing in a stand of predominantly Kentucky bluegrass or perennial ryegrass, apply […]
