Eliminate Unnecessary Risks by Controlling Carolina Horse Nettle
Carolina horse nettle is a perennial forb native to the central and southern regions of the United States and parts of Canada and Mexico. It is considered a toxic weed as all parts of the plant are poisonous to livestock and humans if ingested. Consumption by livestock, including cattle and sheep, can result in gastrointestinal irritation, nervous disorders, weight loss, bloating, and breathing disorders. Unripe berries contain the most poison and while toxicity is constant, it is highest in late summer and fall.
Carolina horse nettle can be found in a wide variety of places, but it is easy to control in rangeland and pasture areas with the appropriate herbicide. It can grow up to four feet tall and has green, hairy stems and prickly leaves. Flowers can be white or lavender and produce a round, yellow or green, berry-sized fruit. Due to Carolina horse nettle's extensive root system, it is best controlled chemically. Alligare's Prescott is ideal for the control of Carolina horse nettle.
In field trials conducted in the growing season of 2022 by university extension services, Prescott’s successful performance replicated that of Alligare’s Gunslinger AMP on Carolina horse nettle (see graph below) and even provided a high level of control on dogfennel. This cutting-edge, range and pasture herbicide is unique in its combination of active ingredients, including triclopyr and clopyralid. Prescott offers lower use rates than the common Gunslinger AMP and Grazon family of broadleaf weed products. It can be applied at a 16-ounce use rate compared to the common rates of 24 or 32 ounces per acre of traditional broadleaf weed, range and pasture products. This level of success with Prescott was achieved without 2,4-D which allows it to be an unrestricted product in the states of Texas and Arkansas.
Prescott is safe on fescue and Bahia grasses while other unrestricted treatment options can cause damage or decrease production of these forages. This solution offers landowners a flexible and unrestricted treatment option with residual activity for broadleaf weed and brush control.
