Bermuda buttercup control8/15/2023 ![]() There are no grazing restrictions associated with this product. Do not plant forage legumes until a soil bioassay has been conducted. ![]() In a seeded field, tall fescue and annual ryegrass are tolerant of 12 fl oz per acre of DuraCor once plants have developed 3 collared leaves. If application rates greater than 12 oz per acre are used, then there is a 45-day planting back restriction. Annual warm-season grasses such as teff grass, crabgrass, sorghum-Sudan hybrids, and pearl millet can be seeded after a minimum of 30 days following a Duracor application of 12 oz per acre. Cool-season annual grasses such as tall fescue and annual ryegrass can be reseeded in an area treated with Duracor after a minimum of 15 days following an application of 12 oz per acre. This herbicide can be mixed with liquid fertilizer (even at low temperatures) or impregnated dry fertilizer. Use a minimum application volume of 10 gallons of water per acre. Application rates range from 12 to 12 oz per acre plus nonionic surfactant (NIS) at 0.25% v/v or methylated seed oil (MSO) at 1% v/v. It can be used in permanent grassland systems (annual and perennial grasses grown for grazing or hay) and in Conservation Reserve Program (CRP) acres. Some of these weeds include thistle, ragweed, pigweed, wild carrot, ironweed, woolly croton, cocklebur, curly duck, henbit, horsenettle, and plantain, etc. The cost of the product ranges from $7 to $9 per oz of product.ĭuraCor TM is a non-restricted postemergence herbicide that can provide control to over 140 weeds. This is due to that this herbicide can stay on the soil surface for an extended period with no degradation from sunlight while waiting for rainfall for activation. There is a two-year planting back restriction for perennial grasses (including sprigged bermdagrss), annual grasses, and legumes in areas treated with Rezilon. A fall application is recommended to control late fall and early winter weeds while a late winter application is recommended for year-round annual grass control. There are no grazing restrictions associated with this herbicide. When this product is applied at a rate greater than 3 oz per acre, there is a 40-day hay cutting restriction. ![]() This product can be applied at a rate of 3 to 5 oz per acre and to exceed more than 6 oz per acre per year. Rexilon is an herbicide that requires activation by rainfall under amounts ranging from 0.25 to 0.5 inches. Some of the target weeds include buttercup, annual ryegrass, goosegrass, annual foxtail, and little barley. Rezilon TM (Indaziflam) is a pre-emergence (should be applied well before expected weed germination) herbicide that can be applied in the fall or early spring to bahiagrass or bermudagrass hay fields to control some annual broadleaf weeds and grasses. Before using a herbicide, always consult the label for the intended use of a herbicide product. hay), the time of the year, environmental conditions (temperature and rainfall), potential forage crop injury, cost of treatment, and haying, grazing (feeding), and plant-back restrictions. Herbicide selection should be based on the type of forage and weed species that are present in the pasture or hayfield and the herbicide treatments should be based on factors such stage and severity of the weed population, residual control (soil type), the intended use of the forage (pasture vs. In the last year, several new pre-and post-emerge herbicides have been introduced in the pasture and range market as potential management strategies. To effectively control weeds in pastures and hayfields, herbicides can be a good management tool when used properly and when cost-effective. ![]() Therefore, production practices that result in low fertility (low pH and nutrient levels), cutting at the wrong stage of maturity, not allowing seeds to become well-established in newly established fields can have a major impact on the presence of weedy species and their competition. The way a hayfield is managed can also have an impact on the weed species and population. These weeds can also affect the aesthetic of hay fields. Several cool-season annual weeds impact hay production systems such as annual ryegrass, buttercup (Yellowtop), wild-barley, henbit, Carolina geranium among others. Weeds can impact the stand of perennial warm-season pasture and hay fields by delaying spring green-up and reducing early yield potential. ![]()
