Most of us remember a connection between fireflies and corn rootworm hatch. This connection may not be absolute and could have changed since we’re now using different production practices than in the past. We also know a lot more about corn rootworm biology. In Ohio, western corn rootworms are by far the most common (although you may see some northern corn rootworms).
In recent years Ohio has seen a huge resurgence of rye usage as a cover crop. While rye can be a good option as a cover crop, it is also a persistent threat as a weed in subsequent crops and neighboring fields. In parts of Ohio this season, volunteer rye is obvious in many crop fields. This is usually a minor threat to the crop, but in certain circumstances, it does create big problems.
The next session of CORN Live is this Thursday, June 24th from 8:00 – 9:00 am. This week’s webinar will touch on a variety of issues, starting with a crop progress report and field updates from Jason Hartschuh, Extension Educator in Crawford County, and a review of weed management in soybeans with Mark Loux, Professor and Extension Specialist in Weed Science at OSU.
Though not in the heart of Tornado Alley, Ohio certainly deals with its fair share of severe weather. The season typically ramps up during May and June, but severe weather so far in 2021 has been rather benign.
It can be nice to see old friends. Except when they cause crop and yield loss, refuse to leave after a few days, and don’t respond to chemicals. A while back we wrote about what appeared to be an increase in populations of dandelions and other winter weeds and made some guesses about why this was happening. Canada thistle has once again become a problem in some fields in a big way, probably for some of the same reaso
Poison hemlock seems to be on everyone’s radar more than usual this year, especially in northern Ohio. We know that while hemlock has been all over southern Ohio for years, it is continuing to spread northward, where new occurrences and observations of it may be engendering concern in the general public and local government. There have also been comments that it seems “worse than usual” this year in
Wheat harvest is rapidly approaching, and with relatively high soybean prices, we anticipate many growers will be interested in double cropping soybean after wheat. According to the U.S. drought monitor (https://droughtmonitor.unl.edu/), areas bordering Michigan are abnormally dry, but throughout the rest of the state, soil moisture is good. Early wheat harvest, high soybean prices, and adequate soil moisture make double-crop soybean an attractive option in 2021.
There is a general interest in applying sulfur fertilizer to maximize corn productivity and we’ve heard industry professionals claim that sulfur deficiency this widespread across Ohio. How much truth is there to this? Do we have a widespread sulfur deficiency in Ohio?
CORN Live session focuses on weed management in soybeans and wheat harvest. We will have field updates from Jason Hartschuh, Mark Loux, John Hoffman, and Brad Moffitt. The webinar is on June 24th, 8 am-9 am. Register at www.go.osu.edu/cornlive. The official flyer is located here.
