Add 1 to 2 qts.surfactant per 100 gals. of water oran oil-in-water emulsion (5% diesel 95% water).Spray the sides of the stump andthe outer portion of the cut surface,including the cambium, immediatelyafter cutting, to thoroughly wet thestem and root collar area, but not tothe point of runoff.RemarksTreatments will control many weeds. When usingoil-in-water emulsion use emulsifier. Use of atreatment with a low control rating may result inmulti-stem growth that may be more difficult tocontrol in the future.If treatment is appliedprior to optimum soiltemperatures, efficacy willbe decreased and multipleapplications over a periodof years may be necessaryto maintain less than 10%canopy.Any season of the year,except when snow orwater prevents spraying tothe ground line.This is commonly called the cut stump applicationmethod. Apply with a backpack or knapsacksprayer using low pressures and a solid cone orflat fan nozzle. This is an excellent treatment to useafter cutting mesquite with hydraulic shears.

For optimum rootkill do not spray if whiteflowers or bean elongationare observable, if over25% of the leaf canopy isdamaged due to insects,disease or hail, if soiltemperatures are lessthan 75 F, 1 ft. deep, or ifnew vegetative growth ispresent due to recent rains.Use 1 pt./acre Tordon 22K plus ½ pt./acre Remedy,½ pt./acre Banvel plus ½ pt./acre Remedy, 1 pt./acre Tordon 22K plus ½ pt./acre Banvel, 1 pt./acreTordon 22K plus ¹ 3 qt./acre Reclaim and 1 3 qt./acre Reclaim only in West Texas. Banvel and Banvelmixtures have been more effective in West Texasthan in other parts of the state. Use mixtures thatinclude ¼ pt./acre Remedy and 1 3 pt./acre Reclaimonly in Montague, Wise, Parker, Hood, Somervell,Bosque, Coryell, Lampasas, Burnet, Blanco, Kendall,Bandera, Real, Edwards and Val Verde countiesand those counties north and west of the namedcounties. Mixtures that include ½ pt./acre Remedyand 2 3 pt./acre Reclaim will give better controlthan mixtures with ¼ pt./acre Remedy and 1 3 pt./acre Reclaim. When using oil-in-water emulsion,use emulsifier added to oil for proper emulsion.Use of a treatment with a low-control rating mayresult in a multi-stem growth form that may bemore difficult to control in the future.Any time; best resultshave been obtained withlate summer through fallapplications.Use emulsifier when adding diesel fuel oil towater. Use 1 pt./acre Tordon 22K only on HighPlains where no brush overstory is present. Latesummer or fall applications, especially with Vista,will provide best results, but aerially spray in thewinter or early spring if heavy overstory of woodyplants is present or if damage to live oak is aconcern.
