Regardless of whether it is a tall fescue and legume pasture, a bermudagrass hay field or an alfalfa hay field; most annual and perennial broadleaf weeds reduce forage yield, palatability and quality. This is particularly true if heavy populations are not controlled on a timely basis and are allowed to reach maturity. In a pasture they also reduce grazing efficiency, which means cattle spend more time picking through and around weeds looking for grass and less time eating. Information and Resources
Arrowleaf Sida/Prickly Sida Prickly sida, also an erect, summer annual herb, is more commonly known as false-mallow, Indian mallow, spiny sida or teaweed. Both arrowleaf and prickly sida are members of the mallow (Malvaceae) family and are native to North America.
Nodding Spurge
Nodding spurge is an erect, summer annual herb that is a member of the family Euphorbiaceae. It is closely related to, and often confused with, spotted spurge, Chamaesyce maculata (L.) Small. This native of North America occurs throughout Tennessee; it is a troublesome weed in row and vegetable crops, ornamentals, rights-ofway, pastures and hay fields, and many other situations.

Bermudagrass Stem Maggot
The bermudagrass stem maggot (Atherigona reversura) is becoming a troublesome insect in bermudagrass pastures and hayfields across Tennessee. The discoloration of the upper leaves causes the field to look like there has been a light frost. If left uncontrolled, up to 80 percent of the tillers in the field can be affected, resulting in significant yield reduction.
Pasture Weed Fact Sheet: Herbicide Stewardship
Troublesome annual and perennial broadleaf weeds must be managed to optimize pasture quality and productivity. In most cases, broadleaf herbicides are necessary ingredients in a pasture weed management program.
A Simple Method to Calibrate Sprayers
Before you can accurately apply the right amount of herbicide to a field, you have to know how much spray mix is being applied to each acre.

Competition Control in Native Warm-Season Grasses
Native grasses planted for forage production in the mid-South must compete with unwanted weeds and grasses. When that competition impacts stand vigor, quality, longevity or production, it should be controlled. Although some competition is inevitable, there are several steps you can take to minimize it.

Johnsongrass
Johnsongrass, Sorghum halepense (L.) Pers., is a member of the grass or Poaceae family. Johnsongrass is a very troublesome weed, as it is capable of extensive seed production and can propagate from creeping, thick rhizomes.
Horsenettle
This native of southeastern North America is found throughout Tennessee; it is particularly troublesome in grass pastures and hay fields. As is the case with most other weeds, prevention is an important component of an overall management plan.
Poison Hemlock
Poison hemlock, also called deadly hemlock, poison parsley, spotted hemlock, and California fern, is a highly poisonous bien-nial weed that is a member of the family Apiaceae, which is also referred to as the carrot family.
Tumble Mustard
Tumble mustard, also known as tall hedge mustard, Jim Hill mus-tard, and tall rocket, is a winter annual or biennial member of the Brassicaceae or mustard family.
