SWITCHGRASS ESTABLISHMENT AND MAINTENANCE FOR BIOFUEL, FORAGE, ETC.
Paramount herbicide is intended for use in fallow systems, grass grown for seed, preplant wheat, preplant and in-crop sorghum and noncrop areas. Paramount is formulated as a dry flowable designed for dilution with water and spraying in common agricultural spray equipment. When used as directed, Paramount will provide suppression or control of weed species listed in Table 1 of the label.
Paramount Application Area
For application regions for Paramount, see Figure 1. Paramount may be used in the following counties of Texas: Archer, Armstrong, Bailey, Baylor, Borden, Briscoe, Brown, Callahan, Carson, Castro, Childress, Clay, Cochran, Coke, Coleman, Collin, Collingsworth, Concho, Cooke, Cottle, Crosby, Dallam, Dawson, Deaf Smith, Denton, Dickens, Donley, Fisher, Floyd, Foard, Garza, Glasscock, Gray, Grayson, Hale, Hall, Hansford, Hardeman, Hartley, Haskell, Hemphill, Hockley, Hutchinson, Jack, Jones, Kent, King, Know, Lamb, Lipscomb, Lubbock, Lynn, McCulloch, Montague, Moore, Motley, Nolan, Chiltree, Oldham, Parmer, Potter, Randall, Roberts, Runnels, Schackleford, Scurry, Sherman, Sterling, Stonewall, Swisher, Taylor, Terry, Throckmorton, Wheeler, Wichita, Wilbarger, Wise, Yoakum, and Young.
Be sure to obtain and follow all Texas state requirements for Paramount uses.
Mode of Action
Paramount is a systemic herbicide with plant uptake occurring through both the foliage and roots. Resultant herbicide symptoms on susceptible plants include twisting, stunting, reddening and chlorosis. For annual plants, symptoms may take up to two weeks after application to develop with death occurring in about three weeks. For perennial weeds, symptoms may not be evident for several weeks after application, and full effect may not be evident for 3 to 6 months.
When making postemergence applications, weeds must be thoroughly covered with spray because foliar uptake of Paramount by the target weed is important for optimum control. Large leaf canopies shelter smaller weeds and can prevent adequate spray coverage.
Based on the uses described in the label, Paramount should be applied by ground application equipment when possible. Paramount may also be applied using aerial application equipment in certain states. In all aerial applications read and adhere to all drift management guidelines in the label. Due to the possible presence of endangered plant species DO NOT apply Paramount by air in the states or counties listed in Table 2 of the label.
Paramount may be applied as either a broadcast or spot spray application. Applications must me made to actively growing weeds.
For most broadleaf weeds, the most effective control will result from applying Paramount early when weeds are small. Delaying application permits weeds to exceed the maximum size and may prevent adequate control.
In irrigated areas, it may be necessary to irrigate before treatment to ensure active weed growth.
Ground Application (Broadcast)
Water Volume: Use 5 to 30 gallons of water per broadcast acre. When weed foliage is dense, higher spray volumes may be required.
Spray Pressure: Use a maximum of 30 psi (measured at the boom, not at the pump or in the line).
Application Equipment: Use only nozzles that will produce uniform spray patterns and thorough coverage, spaced up to 20 inches apart. Select nozzles designed to produce minimal amounts of fine spray particles. DO NOT use controlled droplet applicator (CDA) nozzles as erratic coverage can cause inconsistent weed control. DO NOT use selective application equipment such as recirculating sprayers or wiper applicators. Use drift reduction nozzles such as Delavan Raindrop Drift Reduction Flat Spray Tip, RF Tips, XR Tee Jet Extended-range Flat Spray Tips, or other brands of comparable capabilities.
Avoiding spray drift at the application site is the responsibility of the applicator. The interaction of many equipment- and weather-related factors determines the potential for spray drift. The applicator and the grower are responsible for considering all these factors when making decisions.
For bindweed control in Oklahoma, New Mexico and the designated counties of Texas, the use of methylated seed oil plus AMS is mandatory with Paramount herbicide when it is applied alone.
RESTRICTIONS AND LIMITATIONS
DO NOT apply to weeds or grasses under stress due to lack of moisture, herbicide injury, mechanical injury or cold temperatures, as unsatisfactory control may result.
DO NOT apply to crops subjected to stress conditions such as hail damage, flooding, drought, injury from other herbicides, or widely fluctuating temperatures, as crop injury may result.
DO NOT use selective application equipment such as recirculating sprayers, wiper applicators, or shielded applicators.
DO NOT apply Paramount using aerial equipment in specific states or counties listed in Table 2 of the label.
DO NOT apply through any type of irrigation equipment.
DO NOT allow spray containing Paramount to drift onto areas where tomatoes are to be planted, have been planted, or onto emerged tomatoes, as severe injury will occur.
DO NOT use Paramount in tank mixes not specified on the label.
DO NOT premix Paramount with fungicides, herbicides, insecticides, additives, or fertilizers as contamination of mixing equipment and movement of Paramount to off-site mixing areas can occur.
SWITCHGRASS ESTABLISHMENT AND MAINTENANCE FOR BIOFUEL, FORAGE, WILDLIFE HABITAT, AND CONSERVATION PLANTINGS
Paramount may be used for the establishment and maintenance of switchgrass. Apply 5.3 to 8 ozs/acre Paramount at planting or as an early postemergence treatment for weed control in newly planted switchgrass. Paramount may be applied with other labeled herbicides to improve the spectrum of weeds controlled during the establishment and maintenance of switchgrass.
