Postemergence control of seedling broadleaf weeds, yellow nutsedge and annual sedges in warm- and cool-season turf, nonbearing fruit or nut trees, and selected field-grown ornamental trees, shrubs, and groundcovers.
|Amount of Active Ingredient||Amount by Formulation|
|Per Acre||0.75 to 1 lb||24 to 32 oz|
|Per 1,000 sq ft||0.55 to 0.75 fl oz|
Annual sedges, mallow, purslane, smartweed, velvetleaf, wild buckwheat, wild mustard, Canada thistle, yellow nutsedge, and young seedling dayflower. Control of spring-germinating horseweed has also been observed, but fall-germinating horseweed was not controlled.
Grasses, perennial broadleaves, and mature weeds are not controlled. Purple nutsedge, dandelion, plantain and woodsorrel are not controlled. Many broadleaf weeds are not well controlled when they are larger than 6 to 8 inches tall. See label for details.
Apply as a directed spray to small, actively growing weeds when soil moisture is good. Thorough coverage is essential for best results. For yellow nutsedge, two applications are recommended; the first in mid- to late June and the second 7 to 10 days later. For Canada thistle control, treat when the weed is between 8 inches tall and the bud stage; re-treat 7 to 10 days later. The addition of 1 qt/A of crop oil concentrate is recommended. Allow 8 hours of drying time.
Addition of crop oil concentrates will increase activity; however, crop foliage may be burned when humidity and temperature are high. Do not use on food crops within one year of harvest. Injury has been reported from directed applications around sycamore and Taxus (yew). Liriope is labeled but the variegated forms are more sensitive and are often injured.
No loss occurs from volatility or photodegradation. Bentazon is rapidly absorbed by soil organic matter and degraded by microbes; therefore, leaching potential is low.
Contact burning action. Translocation is minimal in most species. Symptoms may take up to several days to develop. Higher temperatures and addition of crop oil may accelerate and increase the incidence and severity of burn. In some sensitive species, interveinal chlorosis followed by necrosis may occur.
