Read the complete UF/IFAS Smutgrass Control recommendations here for details, but a summary of control options and their positives and negatives include:
- Burning: While burning is thought to increase the germination of seeds in the soil seed bank and thus increase the number new plants, livestock can forage on the emerging plants for two to three weeks.
- Mowing: Mowing is believed to increase the density of smutgrass clumps, but like burning it allows for weeks of grazing on new growth.
How do I get rid of smutgrass?
If you wish to practice smutgrass control on your property in areas outside of the lawn and flower bed, get rid of smutgrass by use of suitable herbicides. Painting plants can be effective, but is not practical when they must be controlled in large quantities.
What is the best time of year to spray for smutgrass?
The best time to apply post-emergent herbicides is when the weeds are actively growing. For many areas where Smutgrass typically grows, it is in May and June when rainfall occurs more frequently. Other areas may do better spraying in July or August right in the middle of summer.
What is the best pre-emergent prevention for smutgrass?
For pre-emergent prevention of weeds, we recommend using Barricade. Barricade is not specifically labeled for smutgrass, but it contains the highly effective active ingredient Prodiamine which controls and prevents seeds from sprouting.

Pour-ons are effective against sucking and biting lice on beef cattle. Injectable avermectins (e.g. ivermectin) are only effective against the sucking lice. Remember that your treatment success will depend on the proper dosing of all animals in the herd.
What grass should cows not eat?
Current theory is that the stuff the cows don't like is "bromus diandrus roth" AKA "ripgut brome" which when young can look very much like a cereal (per wikipedia) and grows well under "heavy thatch and oak canopies" (per the Field Guide for Common California Rangeland and Pasture Plants). Possibly a different brome.
What hay can cattle not eat?
Make sure alfalfa hay is not moldy or dusty. Some molds can cause respiratory problems or abortion in pregnant cows. Avoid stemmy, coarse alfalfa. Protein and nutrition is mainly in the leaves, so stemmy hay is less nutritious and low in protein.

What is the best product to treat smut grass?
Our top products to treat Smutgrass is Barricade for Pre-emergent control and Glyphosate 4 for post-emergent control.
How to calculate glyphosate 4?
To do this, you will need to measure and multiply the area length times width (length x width = square footage). For handheld sprayer mixing, Glyphosate varies depending on the concentration level (1/2% to 10%). You may need to adjust the rate of application depending on the texture of the soil. On coarse-textured sandy soils, a lower rate is preferred. A higher rate is recommended on soils that are fine in texture, such as that of clay loams.
How much water to spray on 1000 sq ft?
A higher rate is recommended on soils that are fine in texture, such as that of clay loams. For general spraying use the 1% concentration at 1.33 oz. in a gallon of water to treat 1000 sq. ft. So for example, if you are treating a 2,500 square foot area, you would need to mix 3.325 fl. oz. in 2.5 gallons of water.
What is the concentration of glyphosate?
For handheld sprayer mixing, Glyphosate varies depending on the concentration level (1/2% to 10%). You may need to adjust the rate of application depending on the texture of the soil. On coarse-textured sandy soils, a lower rate is preferred. A higher rate is recommended on soils that are fine in texture, such as that of clay loams.

How to treat smutgrass?
Small patches may be mechanically removed by hand, although this method is labor-intensive. The best method by far is the use of herbicides. A pre-emergent before Smutgrass seeds have germinated is your best bet in controlling the weed.
How to control smutgrass?
It will simply produce more tillers, re-grow and the clump will become larger. There are limited herbicides available for its control. Velpar is labeled for smutgrass control. Velpar is not inexpensive. It also must be applied correctly and under the right conditions to effectively control the smutgrass. Most of the herbicidal action of the Velpar is due to root uptake by the smutgrass. For proper root uptake, there must be adequate soil moisture at the time of application. It is also beneficial to receive a light to moderate rain within a few days of the Velpar application. The rain will move the herbicide into the soil zone where it will be absorbed by the roots. Velpar also is most effective on rapidly growing smutgrass. If the smutgrass is stressed by drought or other weather conditions, the herbicide will be less effective. Velpar will also injure the Bermuda grass or other summer forages that you want to grow. Recently, label restrictions for grazing following an application of Velpar have changed. Be sure to follow all directions and restrictions for any pesticide you apply. Some producers have had very favorable results with Velpar. Others haven’t. I believe that the main reason for this inconsistency is due to the weather conditions at the time of its application and immediately after application.
What happens if you plough smutgrass?
If the smutgrass is plowed in a period of dry weather, the roots will desiccate and the clump will die. The soil must be dry or the smutgrass clump will merely re-root and begin to grow again.
Why are my smoky seeds black?
These seeds are borne on a stem and are often infected with an ergot fungus that turns the seed black in color. These tiny, black seed give the impression that the stem is covered with “smut.". The seeds are one characteristic that make the plant so much of a problem. It produces many thousands of them.
Does Velpar kill smutgrass?
The rain will move the herbicide into the soil zone where it will be absorbed by the roots. Velpar also is most effective on rapidly growing smutgrass. If the smutgrass is stressed by drought or other weather conditions, the herbicide will be less effective.
Is Velpar herbicide cheap?
Velpar is not inexpensive. It also must be applied correctly and under the right conditions to effectively control the smutgrass. Most of the herbicidal action of the Velpar is due to root uptake by the smutgrass. For proper root uptake, there must be adequate soil moisture at the time of application.

How to control smutgrass?
Read the complete UF/IFAS Smutgrass Control recommendations here for details, but a summary of control options and their positives and negatives include: 1 Burning: While burning is thought to increase the germination of seeds in the soil seed bank and thus increase the number new plants, livestock can forage on the emerging plants for two to three weeks. 2 Mowing: Mowing is believed to increase the density of smutgrass clumps, but like burning it allows for weeks of grazing on new growth. 3 Chemical control: Studies have shown the application of Velpar to be effective and cost-effective if at least 50 percent of the field is infected with smutgrass (except when aiming to prevent smutgrass infestations). However, rain or watering is very important during the two weeks following application, so it’s recommended for application from June to September. Velpar use is not recommended within 100 feet of oak trees or with floralta, stargrass, or mulato grasses. Its use also means a 38-day haying restriction, but no grazing restrictions if the application rate is below 4.5 pt/acre (1.13 lb hexazinone/acre). 4 Complete renovation of the pasture: Generally, this is recommended if smutgrass infests 80 percent or more of the field.
How far away can you use Velpar?
Velpar use is not recommended within 100 feet of oak trees or with floralta, stargrass, or mulato grasses. Its use also means a 38-day haying restriction, but no grazing restrictions if the application rate is below 4.5 pt/acre (1.13 lb hexazinone/acre).

As a full-service custom dry & liquid fertilizer blender and crop protection product distributor, we will continue our mission to further advance Florida agriculture.
Where does smutgrass grow?
Smutgrass is an invasive species that hails from tropical Asia. It is found in two forms in Florida pastures: small smutgrass and giant smutgrass (or West Indian Dropseed), with the latter being the most prevalent in Central and South Florida. Mature smutgrass plants of both forms are unpalatable to livestock, and the plants both produce a large number of seeds, allowing smutgrass to quickly squeeze out bahiagrass, bermudagrass, and other palatable pasture foliage. The one positive about smutgrass is the immature form of the plant is palatable to livestock, offering forage quality equal or greater to bahiagrass.
Does mowing smutgrass increase density?
Mowing: Mowing is believed to increase the density of smutgrass clumps, but like burning it allows for weeks of grazing on new growth.
Is smutgrass palatable to livestock?
Mature smutgrass plants of both forms are unpalatable to livestock, and the plants both produce a large number of seeds, allowing smutgrass to quickly squeeze out bahiagrass, bermudagrass, and other palatable pasture foliage.
How to control smutgrass?
Chemical control of smutgrass includes applying hexazinone at 0.5–1.0 lb/acre (Velpar/Tide Hexazinone at 1–2 qt/acre; Velossa at 0.84–1.67 qt/acre) to small and giant smutgrass. Use lower rates when a multi-year approach is planned. Even when the highest rate is used, a second application during the following growing season may be warranted. A surfactant may be added to Velpar (Velossa contains a surfactant), but recent research has indicated that a surfactant is not necessary because the herbicide works primarily by root uptake. Mowing or burning smutgrass prior to hexazinone application does not increase control. Hexazinone should be applied from June through September, when rainfall is typically sufficient to move the herbicide into the root zone for uptake. There is little foliar activity from hexazinone on smutgrass. If rainfall does not occur within one week after application, the herbicide treatment will likely fail. The same can be said for rainfall that exceeds 3 inches within one week after application. There are no grazing restrictions for hexazinone if the application rate is below 1.13 lb/acre. However, there is a 38-day haying restriction.
When to apply hexazinone to smutgrass?
Mowing or burning smutgrass prior to hexazinone application does not increase control. Hexazinone should be applied from June through September, when rainfall is typically sufficient to move the herbicide into the root zone for uptake. There is little foliar activity from hexazinone on smutgrass.

They adhere to livestock and machinery and also travel via water and wind. Natural seed germination has been shown to average less than 9%, and seed are thought to remain viable in the soil for at least two years.
How far away from oak trees can you apply hexazinone?
Do not apply hexazinone within 100 feet of oak trees because application within this range may cause tree death.
How long does it take for smutgrass to grow?
Burning is thought to increase the germination of seeds in the soil seed bank. However, both burning and mowing allow for approximately two to three weeks of grazing. Smutgrass forage quality during this two- to three-week window is often equal to or slightly greater than bahiagrass.
When to apply Velpar hexazinone?
Apply 2.0 qt/acre Velpar/Tide Hexazinone (1.67 qt/acre Velossa) during the summer rainy season, but no later than the end of September. Apply when plants are actively growing and rainfall is dependable and consistent. Retreatment the following year may be necessary.
Does hexazinone increase forage production?
Fertilization after hexazinone application will increase forage production and allow the desirable grass to quickly fill the open areas created by dying smutgrass.
Why do cows like cheatgrass?
At that time of year, the cows prefer the annuals over rank, mature bunch grasses.”. That’s because mature annuals like cheatgrass are softer and more palatable. By that time of year , the sharp seeds have dropped off, and after fall rain, cheatgrass softens up.
What happens when a fire burns hot?
Unless animals remove the fuel, nature takes it out with lightning-caused fires. With excess fuel, a fire burns hot enough to destroy both annual and perennial plants ; the former grass-shrub plant community is replaced by invasive annual grasses like cheatgrass and medusahead.
What are the threats of fire?
In the past several decades, fire has become the biggest threat to natural resources in Western states, destroying wildlife habitat, timber resources, livestock forage and private property. One major factor leading to increased incidence of fire on rangelands has been excessive “fuel” from ungrazed forage.
Can you graze in the fall in BLM?
Most BLM allotments don’t have provisions for fall grazing in their AMP [Allotment Management Plan].”. Without those provisions, ranchers cannot graze in the fall, and millions of acres that could be treated for cheatgrass reduction are not being helped. “Late-season grazing doesn’t hurt the land or grass.
Where was the forgotten map?
The map was prepared by the National Interagency Fire Center in Boise, Idaho. “Forgotten was the fact that ungrazed forage becomes fuel. A small fire going through a grass-shrub landscape that doesn’t have excessive fine fuels doesn’t burn as hot or spread as far.
Does cheatgrass need litter?
Cheatgrass has lots of seeds that remain viable for several years, but when the next crop grows up in the spring, without that cover from the former years’ thatch to protect it from full sunlight, it doesn’t grow as vigorously. It needs the litter and protection from old, dead grass to shade new seedlings.
Is fire a renewal event?
Given appropriate plant community and plant density, fire goes through quickly and lightly, and takes out some of the plants competing for space, and provides nutrients so the remaining plants can thrive better,” explains Alverts. Managing vegetation by grazing extends fire-return intervals, and fire is not very damaging.
How to get rid of smutgrass?
