General Information

General Information

Basagran T/O herbicidemay be used on established bluegrass, fescue, bentgrass, Bermudagrass, bahiagrass, centipedegrass, zoysiagrass, ryegrass, St. Augustinegrass, carpetgrass, and buffalograss.

Basagran T/O is intended for selective postemergence control of broadleaf weads, annual sedges, and yellow nutsedge. Basagran T/O does not control grasses. Basagran T/O is effective mainly through contact, therefore, all plants must be thoroughly covered with spray.

Weeds controlled by Basagran T/O in turf include annual sedges, yellow nutsedge, wild mustard, dayflower, common groundsel, and common purslane. For other weeds controlled by Basagran T/O in turf, see Table 2.

Application Information
Apply Basagran T/O postemergently to actively growing weeds under good soil moisture conditions. If desired control of yellow nutsedge or Canada thistle is not obtained with the first application, make a second application 10-14 days later or when new growth appears.

In the northern United States, yellow netsedge can emerge from May through July, while in the southern United States, nutsedge and broadleaf weeds can emerge throughout the year. Therefore, initial applications should be planned when most plants have emerged. If new plants emerge later in the season, make a second application of Basagran T/O according to the label directions. In unmowed turf, make the first application after emergence but before yellow nutsedge, annual sedge, and Canada thistle are 8 inches tall. Annual broadleaf weeds should be no taller than 4 inches. Thorough spray coverage of yellow nutsedge is essential for maximum control.

For optimum control, do not mow within 3 days before or after application. For sedges, do not mow within 5 days of application.

Use a minimum water volume of 1 gallon per 1,000 square feet (40 gallons per acre) with a minimum pressure measured at the nozzle of 40 psi.

Limitations, Restrictions, and Exceptions

Ornamentals, Nursery, Other Nonfood Crops, Noncrop Sites, Roadsides, and other Rights-of-Ways

Basagran T/O may be applied as a directed spray around all ornamental and nursery plants except sycamore and rhododendron.

Directions for Use
Rate and Timing of Application

Apply Basagran T/O herbicide early postemergence to actively growing weeds before they reach the maximum size listed in Table 2. Early application to weeds produces the most beneficial weed control (exception: yellow nutsedge and Canada thistle). Delaying application permits weeds to exceed the maximum size stated and will result in inadequate control.

Do not cultivate or mow within 5 days before or after applying Basagran T/O.

Addition of Oil Concentrate
Refer to Addition of Oil Concentrate for more information.

Rate of Oil Concentrate
Use 0.75 fluid ounces per 1,000 square feet (2 pints per acre).

Water Volume and Spray Pressure

Apply recommended rates of Basagran T/O with a minimum of 0.5 gallon of water per 1,000 square feet (20 gallons per acre) and a minimum of 40 psi (measured at the boom, not at the pump or in the line). When foliage is dense, use up to 2.5 gallons of water and up to 80 psi. Use standard high-pressure pesticide hollow cone or flat fan nozzles spaced 20 inches apart. Do not use flood, whirl chamber, or controlled droplet applicator (CDA) nozzles.

Special Information for Irrigated Areas

If moisture is not adequate for active weed growth, irrigate before applying Basagran T/O. Weeds growing under drought conditions usually are not satisfactorily controlled.

Over-The-Top Applications
Basagran T/O may be applied over-the-top of certain ornamental species listed in Table 3 and to non-crop sites listed below.

Noncrop Sites, Roadsides, and Rights-of-Ways
Basagran T/O may be used in sites where grass vegetation must be maintained. Avoid drift onto the vegetation as injury may occur. A water volume sufficient to obtain adequate coverage of the weed should be used. Do not make applications to open waters.

Notice to User
Due to the variability within species and in application techniques, neither the manufacturer nor the Seller has determined whether or not Basagran T/O can be safely used on all ornamentals, nursery, and other nonfood sites under all conditions. It is recommended therefore, that the user determine if Basagran T/O can be used safely prior to broad use.

Directed Spray Applications
Apply Basagran T/O around landscape and ornamental trees, shrubs, flowers, and other plants as a directed spray away from the foliage of desired plants, unless otherwise directed.
Injury may occur when applying Basagran T/O as a directed spray under the tree line or over the roots of sycamore and rhododendron. Do not apply if the risk of injury to these plants is not acceptable.

Restrictions and Limitations

Do not apply Basagran T/O herbicide to crop plants that have been subject to stress conditions such as hail damage, flooding, drought, extreme heat, or widely fluctuating temperatures as crop injury may result.
Do not apply Basagran T/O if crop plants show injury (leaf phytotoxicity or plant stunting) produced by any other prior herbicide applications, because this injury may be enhanced or prolonged.

Rainfall or overhead irrigation within 8 hours after application may reduce the effectiveness of Basagran T/O. Do not apply more than 1.5 fluid ounces of Basagran T/O per 1,000 square feet (4 pints per acre) in any 12-month period.

Do not exceed a total of 1 pound of active ingredient (bentazon) per acre per application or 2 pounds of active ingredient (bentazon) per acre per season. One pint of Basagran T/O contains 0.5 pound of bentazon.

Do not exceed a total of 0.367 ounce active ingredient (bentazon) per 1,000 square feet per application or 0.73 ounce of active ingredient (bentazon) per 1,000 square feet per season. One fluid ounce of Basagran T/O contains 0.5 ounce of bentazon.

Clean the sprayer thoroughly before applying Basagran T/O, particularly if a herbicide with the potential to injure the plants to be sprayed with Basagran T/O was previously used. Physical incompatibility, reduced weed control, or ornamental plant injury may result from mixing Basagran T/O with pesticides (fungicides, herbicides, insecticides or miticides), additives or fertilizers.

BASF does not recommend using Basagran T/O tank mixes other than those listed on BASF labels, supplemental labeling, or technical bulletins.

Local professional authorities may be a source of information when using other than BASF recommended combinations. Otherwise, test a small area of the site with the desired tank mix combination and allow 7-10 days to evaluate potential injury.

Do not apply Basagran T/O plus an oil concentrate with other pesticides whose labels caution against their use with oil adjuvants

Restricted Entry Interval
