Battle for the Belt: Season 2, Episode 18- Planting Date and Weed Control Interactions

Champion Belt for Battle for the Belt in corn

Article is taken from https://agcrops.osu.edu/newsletter/corn-newsletter/2024-25/battle-belt-season-2-episode-18-planting-date-and-weed-control by Taylor Dill, Osler Ortez, Laura Lindsey, Alyssa Essman

Episode 18 of Battle for the Belt is now available: https://www.youtube.com/watch?v=xbf-dlV-jmc

In Episode 18, we are with Dr. Alyssa Essman, Weed Control Extension State Specialist, at the Western Agricultural Research Station in South Charleston, Ohio talking about weed management considerations for different planting dates.

Weed Control Considerations
The critical period for weed control is the first four to six weeks after crop planting. This period is when the young plants are most sensitive to competition with weeds for resources such as moisture and sunlight. Timely weed management, especially within this window, will reduce yield loss potential from the presence of weeds. In situations where soybean or corn are planted, but inclement weather prevents us from being able to get back into the field in a timely manner, it is very important to refer to herbicide labels and the weed control guide to evaluate management options. In areas that have had dry weather, the use of adjuvants becomes especially important, as plants develop a thicker cuticle and the herbicide has a harder time getting into the plant.

Weed Control in Corn – Western Site
The fifth planting date (June 17) of Battle for the Belt has more weed competition than the other planting dates at this time, as the plants were not tall enough yet to fully canopy, and the weather had not allowed a post emergence application. The height of weeds, growing past the top of the corn, shows that the weeds have a competitive advantage. In these plots, the plants near the weeds are about a leaf in growth stage behind the plants that are further from the weeds. In earlier planting dates, there is greater canopy closure and fewer weeds.

Pre-Harvest Herbicide Treatments for Weed Desiccation

Note from Sarah: As a drive the insect scouting loop in Paulding County, I am noticing many fields invested with water hemp which is a great concern in weed control. Other things to make note of are barnyard grass, velvet leaf , marestail and volunteer corn.

Waterhemp infestation.

There are plenty of fields with late-season weed problems this year. Weeds that come through the crop canopy late may be small or spindly or sparse enough to be handled easily by a combine. Other fields can benefit from a preharvest herbicide treatment to kill/dissociate weeds, which makes harvesting easier and can reduce weed seed production and foreign matter in harvested grain. Information on preharvest herbicide treatments for field corn and soybeans can be found in the “Weed Control Guide for Ohio, Indiana, and Illinois”, at the end of those crop sections (pages 75 and 146 of the 2022 edition). Products listed for corn include Aim, glyphosate, 2,4-D, and paraquat, and for soybeans include Aim, dicamba, paraquat, glyphosate, and Sharpen. Keep in mind that Aim and Sharpen have relatively narrow spectrums of activity, and will be less effective than the others across a broad range of weed species (i.e. make sure the target weed is something that they actually control).

Relentless Canada Thistle

By: Christine Gelley, Agriculture and Natural Resources Educator, Noble County OSU Extension;

Source: https://u.osu.edu/beef/2022/06/22/relentless-canada-thistle/

The time has come for Canada thistle flowers to line the roadways and begin to bud in pastures and hayfields. The lavender-colored aggregate flowers that develop into fluffy seed are one of the most distinguishing characteristics of the plant. They are easy to find blooming from June through August. If it wasn’t such an unpleasant plant to encounter, I might call it pretty. It isn’t poisonous, thank goodness, but it certainly is troublesome. Some animals will tolerate it while grazing, but most will avoid it while it is growing or sort it out of a hay bale. Continue reading Relentless Canada Thistle →

Enlist herbicide banned in 12 Ohio counties

By Mark Loux, Ohio State University Extension herbicide specialist

The U.S. Environmental Protection Agency issued a new seven-year registration for Enlist One and Enlist Duo, valid through January 2029. Changes include a revised application cutoff for soybeans, “through R1” that replaces “up to R2” on previous labels, and the addition of a slew of spray nozzles to the approved nozzle list. The most significant change for Ohio is that, due to changes in Endangered Species information, Enlist One and Enlist Duo cannot be used in 12 Ohio counties: Athens, Butler, Fairfield, Guernsey, Hamilton, Hocking, Morgan, Muskingum, Noble, Perry, Vinton, and Washington. We contacted Corteva to see if this was likely to change anytime soon, and got no assurances of this, although the PR information they have distributed indicates it is possible.

This really couldn’t happen at a worse time for growers in these counties. We’re in the middle of an endless pandemic, a worldwide shipping fiasco, with herbicide scarcities, price increases, and parts shortages. And just when you had it worked out to use Enlist herbicides on Enlist soybeans for 2022 so you wouldn’t have to deal with dicamba, their use is no longer legal in your county. We’re trying to find something reassuring to say here, but there’s not much. We lack solid information on herbicide availability and price, and it’s a fluid situation, but it appears that glyphosate and glufosinate can be in short supply, and prices are high.

Get your Waterhemp Populations Screened for Herbicide Resistance

By Mark Loux, OSU Extension

We have been screening a random sample of waterhemp populations for herbicide resistance over the past two years.  Herbicides used on the screen include mesotrione, atrazine, 2,4-D, fomesafen, and metolachlor.  Results of our research show that it’s possible for Ohio waterhemp populations to have some level of resistance to one, several, or all of these herbicides.  Glyphosate is not included because we assume almost all populations are already resistant to this.  We are also part of a regional project that has been screening for dicamba and glufosinate resistance with populations that we supply, although none has been identified to date.

Poison Hemlock and Wild Parsnip are Bolting and Blooming

By Joe Boggs (Published on May 16, 2021)

Additional note from Sarah Noggle, Extension Educator in Paulding County. In 2020, Poison hemlock has been found in Paulding County. The densest populations have been located along the railroad beds, overgrown areas along woods, and also old fence rows. Help beautify Paulding County by controlling the weeds along the edges of your property but use caution if you find Poison Hemlock.

Poison hemlock (Conium maculatum) is one of the deadliest plants in North America.  Wild parsnip (Pastinaca sativa) sap can produce severe, painful skin blistering.  Both are commonly found growing together in Ohio and both are beginning to “bolt” and bloom meaning the clock is quickly winding down for controlling these non-native nasties.

Wild parsnip

Poison hemlock

Wild parsnip

These non-native weeds are members of the carrot family, Apiaceae.  The old name for the family was Umbelliferae which refers to the umbel flowers.  The flowers are a key family feature with short flower stalks rising from a common point like the ribs on an umbrella.  Queen Anne’s lace (a.k.a. wild carrot) (Daucus carota) is often used as the poster child for carrot family flowers.  This non-native blooms much later in the season.

Scout now for cressleaf groundsel in hayfields, or pay the price in May

Cressleaf GroundselBy Mark Sulc, OSU

Some hay producers have been unpleasantly surprised in the past when cressleaf groundsel infestations became evident in their hay fields in May prior to first cutting.  Cressleaf groundsel in hay or silage is toxic to animals, and infested areas of the field should not be harvested and fed.  Groundsel is a winter annual, emerging in late summer into fall when it develops into a rosette that overwinters.  Growth restarts in spring, with stem elongation and an eventual height of up to several feet tall.  The weed becomes evident in hayfields when it becomes taller than the alfalfa/grass and develops bright yellow flowers in May.  The problem with passively waiting until this point to discover that the hay is infested with groundsel is that: 1) it’s too late to control it with herbicides; and 2) hay from infested areas has to be discarded instead of sold or fed, and large plant skeletons are still toxic even if herbicides were effective on them.  Groundsel plants finish their life cycle in late spring, once they flower and go to seed, so it should not be a problem in subsequent cuttings.
