Selective Grass Control
Drive XLR8
Controls crabgrass, foxtail and barnyard grass if applied at 2 qts/acre to mature plants
Segment II
Apply at 1.5 pint/acre to established mowed fescue areas to control bluegrass, ryegrass, crabgrass, foxtail with limited quackgrass control. Rates above 1.5 pint/A. will injure or kill chewings and creeping red fescue. Hard fescues are tolerant of Segment. Segment will not control tall fescues. In unmowed native areas, Segment rates vary depending on the size of the target grass. Rate of 1-2.5 pints/acre are needed. To avoid damage to little or big bluestem or switchgrass, apply Segment before June 1 or after October 1. Deertongue can be a big problem and should be sprayed late spring or early fall. Deertongue is a warm season grass and it is difficult to control without injuring bluestem or switchgrass. Fall applications of Segment should be done after October 1st. Areas should be mowed two to three weeks prior to spraying and can include post-emergent herbicides. Areas with little to no fine fescue will need to be seeded with Harrell’s Fine Fescue Links Blend after the Segment application to transition into fescues and warm season grasses. When applying Segment be sure to stay within areas to be treated. Segment II should be applied with a crop oil concentrate or methylated seed oil. Pylex 1-1.5 fl oz/A for postemergence control of broadleaf and grass weeds. Pylex should be applied with a crop oil concentrrate or methylated seed oil.
Pylex Herbicide
Esters vs. Amine
Ester Formulations – contain the acid formulation of the active ingredients of 2,4-D and triclopyr (Garlon). The esters are more powerful and active but have less turf safety and can volatilize and move in extreme situations (i.e. T-Zone and Speedzone). Speedzone contains a non-volatile
ester of 2,4-D so it will not move, but is not as effective on brush. Amine Salt Formulations – The amine salt formulations are less volatile and less active. Examples of amine formulations include Confront and Trimec Classic
