Segment- herbicide is a selective, broad-spectrum, postemergence herbicide for control of annual and perennial grass weeds in turf, ornamentals, nonfood, and
noncrop sites listed on this label. Segment does not control sedges or broad leaf weeds. All grass crops, such as sorghum, corn, small grains, and rice, as well as ornamental grasses, such as turf, are susceptible to Segment. A program for total vegetation suppression may necessitate the use of a broad leaf herbicide. Any combination treatment using Segment, either tank mixed or sequential, should be tested to determine if seed head growth suppression is maintained without increased injury or discoloration to tall fescue or other desired plant species. A reduction in grass competition may make certain broad leaf weeds appear more prominent or may allow new weeds to germinate.
Mode of Action
Segment rapidly enters the targeted grass weed through its foliage and translocates throughout the plant. The effects range from slowing or stopping growth (generally within 2 days), to foliage reddening and leaf-tip burn. Subsequently, foliage burnback occurs. These symptoms will generally be observed within 3 weeks depending on environmental conditions.
All labeled crops are tolerant to Segment at all stages of growth. Leaf speckling may occur, but plants generally outgrow this condition within 10 days. New growth is normal, and crop vigor is not reduced.
Notice to User: Due to variability within species, and in application techniques and eqUipment, and the number of tank mix combinations, neither the manufacturer nor the seller has determined if Segment can safely be used on all varieties and species of non bearing food crops, trees, shrubs, ornamentals, bedding plants, ground covers, nursery plants, wildflowers, Christmas trees, turf and other nonfood crops under all conditions. It is recommended, therefore, that the professional user determine if Segment can be used safely before broad use by applying the recommended use rate of Segment under the conditions expected to be encountered on a small test area. Any adverse effects should be visible within 7 days.
Repeated use of Segment (or similar postemergence grass herbicides with the same mode of action) may lead to the selection of naturally occurring biotypes with resistance to these products. If poor performance cannot be attributed to adverse weather conditions or improper application methods, a resistant biotype may be present. Consult your local representative or agricultural advisor for assistance.
In irrigated areas, it may be necessary to irrigate before treatment to ensure active weed growth.
Apply Segment uniformly and completely to the foliage of grasses on a spray-to-wet basis. Dense leaf canopies shelter smaller grassy weeds and can prevent adequate spray coverage. DO NOT spray to the point of runoff.
If cultivation is an option, DO NOT CUltivate during the time between 5 days before and 7 days after applying Segment. Cultivating 7 to 14 days after treatment may help provide season-long control of perennial grasses. Centipedegrass and fine fescue areas should not be mowed within 7 days before or after applying Segment. Increased control has been observed when mowing is delayed until 14 days after application. Grass weeds that have been mowed or have regrown from mowed stubble may be controlled poorly. Repeat application if new germination or regrowth occurs.
Applications (aerial, broadcast, band, or spot spray) can be made to actively growing grassy weeds at the rates and growth stages listed in Table 1, Table 2, and Table 3, unless instructed differently in Crop-specific Information. The most effective control will result from making postemergence applications of Segment herbicide early, when grassy weeds are small. Delaying application permits grassy weeds to exceed the maximum size stated and will prevent adequate control.
DO NOT apply when conditions favor drift from target area or when wind speed is greater than 10 mph.
Ground Application (Broadcast)
Water Volume. Use 5 to 50 gallons of spray solution per acre (1 to 10 pints per 1,000 square feet). Spray Pressure. Use 30 to 60 psi (measured at the boom, not at the pump or in the line). When crop and grass weed foliage is dense, use a minimum of 20 gallons (3.67 pints per 1,000 square feet) of water and 60 psi.
Application Equipment. Use standard high-pressure pesticide flat fan or hollow cone nozzles spaced up to 20 inches apart. DO NOT use flood, whirl chamber, or controlled droplet applicator (CDA) nozzles because erratic coverage can cause inconsistent weed control. Refer to the nozzle manufacturer's directions for recommended height. DO NOT use selective application equipment such as recirculating sprayers or wiper applicators.
