Weed Control Information:


Macartney Rose

Macartney Rose

Description: 6 inches–6 feet tall perennial shrubs with re-curved prickled stems and pink or white flowers.

Leaves: Compound, alternately arranged and green with 3–11 leaflets.

Flowers: Five pink or white with a yellow center.

Treatment:

Broadcast: Apply the labeled rate of 4 quarts of Grazon® P+D herbicide per acre with a nonionic surfactant or oil-water emulsion. Apply in spring or fall when conditions are favorable for plant growth. Thorough and uniform spray coverage is essential. Use higher spray volumes (25 gallons per acre by ground and 5 gallons per acre by air). Apply follow-up treatments at the labeled rate of 2 quarts of Grazon P+D per acre. Avoid application within 12 months after mowing or if plants have a large percentage of new foliage.

Spot: To treat individual plants, use a 0.5% to 1.0% volume/volume solution of Surmount™ herbicide in water. Delay treatments for 9–12 months after mowing. Apply in spring or fall to Macartney rose plants greater than 3 feet tall.


Chinese Tallowtree

Chinese Tallowtree

Description: Chinese tallowtree (popcorn tree) is a rapid growing, non-native deciduous tree reaching a height of 20–50 feet at maturity. Introduced from China as an ornamental, it has since spread to all coastal states from North Carolina to Texas, and into Arkansas, Oklahoma and surrounding states.

Leaves: Light-green alternate leaves, about as wide as they are long, tapering to a point, which become yellow to red in the fall.

Flowers: Stalked white flowers mature into three-lobed fruit, which resemble popcorn when they split open in the fall to reveal white seed.

Treatment:

Broadcast:Elimination of Chinese tallowtree requires follow-up treatments for two to three years following the initial herbicide treatment. Re-check treated areas each year and promptly control new sprouts or seedings.

Apply 1 gallon of Grazon® P+D herbicide per acre. For best results, it is important to achieve thorough and uniform spray coverage. Use higher spray volumes (20–25 gallons per acre for ground equipment and 10–15 gallons per acre for aerial equipment). Use a non-ionic surfactant or oil-water emulsion to help achieve uniform coverage.

Apply 1 quart of Tordon® 22K herbicide per acre. Use higher spray volumes and an approved agricultural surfactant to ensure thorough, uniform spray coverage.

High-Volume Foliar: For small patches of encroaching Chinese tallowtree or individual plants, use the labeled rate of a 1 percent solution (1 gallon of Grazon P+D per 100 gallons of spray) according to the label. For the best control, spray to thoroughly wet the foliage and stems. To minimize spray drift and achieve good coverage, use the lowest possible pressure and coarse spray.

Apply the labeled rate of 2 quarts of Tordon 22K per 100 gallons of spray mix.

Treatment Timing: Apply in spring or fall when conditions are favorable for plant growth. Thorough and uniform spray coverage is required. Use a spray volume of 20–25 gallons per acre for ground or 5 of more gallons per acre for aerial equipment.
