What is weed in hayfield?
First, a weed is defined as any plant growing where you don’t want it. Therefore, we must begin to think in a broader sense as to what weeds are. A weed can be Bahiagrass or Crabgrass growing in a Bermudagrass hayfield. These unwanted plants are often more aggressive than existing or desired forage species and compete for light, water, and nutrients. In latter stages of maturity, weeds can also reduce the quality and palatability of the forage available for livestock grazing. However, not all weedy plants are detrimental to pastures. In fact, some weedy plants provide nutritional value to grazing animals.
How to control weeds from broadleaf?
Mowing is especially effective in reducing the amount of weed seed produced by established broadleaf weeds. The mower should cut as close to the ground as possible. Mowing may not completely eliminate weed seed production, since some seed could be produced by plants that regrow from tillers present on grasses below the height of cutting. Also, perennial weeds that spread by underground rootstocks, like thistle, are not effectively controlled by a single mowing .
What is a post emerge herbicide?
This herbicide is used to control Crabgrass in Bermudagrass hayfields. Post-emerge products are used to kill weeds after they have germinated.

What is alligatorweed?
Alligatorweed is a perennial weed that is a mat-forming member of the Amaranth family. It is a serious aquatic weed problem in the North Carolina coastal plain and is becoming a major pest in pastures and row crops in low-lying areas. Alligatorweed stems are distinctly jointed and hollow except at the nodes. The stems are light green in color, with faint darker green parallel lines extending from one node to the base of the next. Roots are produced at the nodes. Terrestrial infestations produce two types of rhizomes: purplish, horizontal rhizomes that resemble stems with very short internodes, and fleshy, white, rootlike rhizomes. Terrestrial stems usually are pithy or even solid, rather than hollow. Leaves are oval to lance-shaped, have a prominent midrib, and are arranged opposite along the stem. Small, cloverlike, white flowers are borne on short stalks attached in the leaf axils near the end of the stems. Flowering occurs from late April through October. Reproduction is vegetative by fragmentation because very few seeds form.
What does it mean when a volunteer species is a weed?
New volunteer species can mean more and better pasture forage, or it can mean losses of forage quality and yield. Weeds also have the potential to cause injury or death to livestock if the weed plants are toxic. Weeds can reduce hay yield and quality, and they can interfere with hay drying.
How are weeds spread?
Many weeds are spread by seeds that are dispersed by hay bales, plants that reach maturity, livestock movements, mowing equipment, wind, water, and wildlife. Weeds can also be introduced when you plant grass seeds that are contaminated with weed seeds.

What are some weeds that affect hay?
Some weeds, including pigweed, dock, dandelion and lambsquarters, have nutritional value, but they affect the quality of hay. “They dry down differently,” said Lingenfelter. “They reduce the quality of the forage — we don’t want them in the mix.”. Weeds can greatly impact the overall carrying capacity of a hayfield.
How to control weeds in a forage stand?
A combination of measures ensures the best weed control in a forage stand. For establishing hay or pasture, producers should select the species that are appropriate for the region, take soil tests prior to planting and throughout the life of the stand, fertilize according to soil tests, manage harvest and watch for signs of overgrazing. It’s also important to keep fencerows clean — messy fencerows can mean more weeds in pastures. Weeds can be controlled mechanically, with routine mowing at the appropriate time. “We suggest around flowering time, or seed head formation,” said Lingenfelter. “If necessary, treat weeds by hand.”
Why should herbicides not be applied to plants?
For example herbicides should not be applied when plants are stressed from drought or heat. Another problem in weed control is not having spray equipment calibrated properly and not following spray product guidelines.
What are the challenges of weed control?
One of the challenges in weed control is that life cycles and growth patterns vary. This causes problems both during establishment and throughout the life of the stand.

Why is hay important?
Hay is an important crop for livestock producers, and should be treated the same as any other crop when it comes to weed control. Weedy hay results in decreased yields, short-lived stands and potential harmful effects to livestock. Weeds in forages compete for nutrients, light moisture and space. They reduce the quality ...
When is it time to rotate out of a pasture or hayfield?
When is it time to rotate out of a pasture or hayfield? “If weeds or bare areas comprise less than 30 percent of the field, good agronomic practices will improve the field,” said Lingenfelter. “Use of the appropriate herbicide and mowing can provide improvement. If weeds and bare ground are between 30 percent and 50 percent, a combination of herbicide and overseeding for an improved stand should be considered. If weeds and bare ground are more than 50 percent, evaluate how that happened. Renovation might improve the stand in the long run, but it’s important to understand what led to the need for renovation. If the stand is too weedy, overgrazed or has poor fertility, simply renovating will not have a long-lasting effect on the stand. It’s important to understand how the stand got that way — renovate only as a last resort.”
What is the best way to start a hay stand?
Fertility and a well-prepared, firm seedbed are important in establishing hay. Consider companion crops such as triticale or oats to help the stand get started. “It’s the first 60 days that are the most important to give the crop a competitive advantage,” said Lingenfelter.
