How do you get rid of foxtail barley?
Targeted use of glyphosate plus selective in crop herbicides in oilseeds and pulses are the backbone of foxtail barley control programs. With early seeding, a half litre of glyphosate pre-seed followed up with Assure II post-emergence gave good control. Photos Courtesy Of Ken Sapsford, University of Saskatchewan.
What herbicide will kill foxtail?
Since foxtail is a grass, broadleaf herbicides do not control it. Glyphosate is a non-selective herbicide that will kill foxtail as well as most all other plants (grasses and broad leaved). Check out the fact sheet on toxicity, Glyphosate Questions & Answers.
How do I get rid of foxtail grass?
There is one pre-emergent herbicide approved for pasture use in Pennsylvania called Prowl H2O that you apply in the spring, before the foxtail seedlings emerge, that will prevent them from growing. It is also effective on other summer annual grasses like crabgrass and some broadleaf weeds. This method has a few drawbacks.

To give your lawn the nutrients it needs to grow thick and lush while also killing and preventing foxtail, crabgrass, and other listed weeds, ...
What is the best way to control foxtail weed in the summer?
If foxtail weed pops up in your lawn in summer, you can control it using Ortho® Weed B Gon® Plus Crabgrass Control Ready-to-Useor Roundup® For Lawns1 Ready-to-Use(for Northern grasses). When used as directed, it will kill actively growing foxtail without harming your lawn.
What is foxtail grass?
Foxtail weed is an annual grass that, like crabgrass, rears its ugly head in summer. It gets its name from the bushy seed heads it produces, which look like foxes’ tails. There are three different varieties of foxtail weeds: yellow, green, and giant.
What is the best defense against weeds?
A thick, lush lawn is the best defense against weeds. Regular fertilizer applications will not only improve your lawn’s appearance, but will also strengthen and thicken the grass to help crowd out weeds. Along with feeding the lawn, mowing at the proper height is important.
Can foxtail weed grow in dry soil?
Foxtail weed can grow in a wide range of conditions and can be found in both moist and dry soil. It has wide, flat leaf blades that look similar to crabgrass, but is easily distinguished from crabgrass when the seed heads form in summer.
When does Foxtail Barley produce seeds?
Seed production for this grass occurs from late May to August. Foxtail barley at lower elevations (warmer regions) will produce seeds earlier than higher elevations (cooler regions). Grazing this plant after it produces seeds can cause a number of problems for animals.
When is Foxtail Barley grass good for pasture?
Foxtail barley growing in a pasture, an area often ponded during the spring. Livestock can safely graze foxtail barley prior to seed development. Forage value of this grass is fair to good at this time. Seed production for this grass occurs from late May to August.
What magnification do Foxtail Barley awns have?
Foxtail barley awns at 4X magnification, displaying barbs. Movement of contaminated hay offsite to a different location for any purpose, even if not fed to animals, is likely to further spread seed. Areas that are wet in the spring are the most likely to be invaded.
Can you use Roundup on Foxtail?
Although effective, mechanical treatment and seeding may not always be required. In some situations, foxtail may occur in smaller bunches and patches. When this occurs spot treatment with the generic herbicide glyphosate (e.g. Roundup ®) can be effective in controlling the plant.
Is foxtail barley a problem for livestock?
Unlike in rangeland situations, animals fed hay contaminated by foxtail are unable to avoid eating the plant. Contaminated hay is unsafe for livestock. Livestock that have eaten contaminated hay may show symptoms such as drooling and lack of appetite.
How to control foxtail barley?
Given the variability in yields with late seeding, Sapsford says the best strategy for foxtail barley control, when fall applications were not successful, is to use an early pre-seed glyphosate application, followed by Assure II in pulse and oilseed crops. That is similar to Blackshaw’s recommendation, who also recommends a follow-up treatment with one to 1.25L/ac glyphosate post-harvest. “This approach should kill small seedlings before they become large clumps, which is very important, and will reduce the population of larger established plants over time,” explains Blackshaw.
What is the purpose of foxtail barley control?
A final component of foxtail barley control is to increase crop competitiveness . Blackshaw says his research has found that higher wheat and barley seeding rates will suppress foxtail barley plants and reduce seed production or future infestations.
How much glyphosate should I use for seedlings?
With early seeding, a half litre of glyphosate pre-seed followed up with Assure II post-emergence gave good control. Photos Courtesy Of Ken Sapsford, University of Saskatchewan.
When was glyphosate burndown applied?
In 2005, a half litre per acre glyphosate pre-seed burndown was applied and then wheat was seeded a few days later. In 2006 and 2007, flax was grown. The pre-seed burndown was conducted either during the first week of May, or the last week of May. The crops were sown a few days later. In wheat, Sundance was applied post-emergence and in flax, Assure II was applied post-emergence.
When to apply glyphosate to foxtail barley?
A more consistent timing can be September and October, but success depends on fall rains that promote foxtail barley growth. Blackshaw has found that glyphosate at one litre per acre applied pre-harvest or post-harvest can be expected to provide greater than 80 percent control of established plants if they are actively growing. “There is little benefit in going to higher rates of glyphosate. Actively growing plants are more important than increasing rates,” explains Blackshaw.
Is Foxtail Barley a weed?
Blackshaw has conducted several studies on foxtail barley in recent years. He says that foxtail barley becomes a more serious weed problem when tillage is reduce d. And since reduced tillage and no-till are now the dominant seeding systems in western Canada, foxtail barley, which is easily controlled by tillage, is starting to spread beyond its normal saline soils locale.
Is Foxtail Barley a competitor?
By Bruce Barker. Topics. Agronomy. Weeds. Foxtail barley is one prolific competitor producing several thousand se eds per plant. To go after it, a choice of herbicides and tillage can provide flexibility in dealing with varying environmental conditions from season to season. Targeted use of glyphosate plus selective in crop herbicides in oilseeds ...
How to control foxtails?
Control of foxtail involves efficient irrigation management and grazing management that keeps the preferred species strongly competitive. Avoid letting water stand in low places so long that it drowns out the desirable grass and legume species. Infested pastures should be plowed and reseeded.
When does foxtail barley dry?
Foxtail barley is usually found on sites that are moist or flooded in spring, with the surface drying by mid summer with the water table remaining in the upper meter of the soil profile. It can also grow on sites that periodically receive extra moisture such as roadsides and irrigated pastures.
What type of soil does Foxtail Barley grow in?

When does foxtail grass germinate?
Answer: Foxtail is an annual grass that germinates in the spring when soil temperature averages 65 degrees for three consecutive days. Alexander County soil temperature data from 2009 to 2018 shows 65°F three-day average soil temperature occurred between April 22 and May 9. This is why foxtail is typically a problem for the second hay cuttings.
