Pylex Herbicide

General Information

Pylex™ herbicide is the standard for the control of Bermudagrass and goosegrass in cool-season turf, providing unmatched performance on these difficult-to-eliminate weeds. It has also shown excellent control of nimblewill, crabgrass, clover, speedwell, and others. Pylex herbicide should always be used with a crop oil concentrate (COC) to improve herbicide coverage, resulting in improved weed control.

Pylex herbicide has shown it is safe to most cool-season grasses such as Kentucky bluegrass, tall fescue, fine fescue, and perennial ryegrass.  It has shown varied tolerance on bentgrass (moderate to severe injury) and annual bluegrass (minimal to moderate injury) at labeled use rates. Warm-season turfgrass is sensitive to Pylex herbicide, with the exception of centipedegrass, which is tolerant.

Controlling Bermudagrass: Two to three late-summer applications spaced three weeks apart have shown best results. Tank mixing Pylex herbicide with triclopyr at two pints per acre has provided greatest control and also significantly reduces the bleaching.

Aug. 1: Pylex herbicide 1.5 oz./A + triclopyr 32.0 oz./A + crop oil concentrate at 0.5% v/v

Aug. 21: Pylex herbicide 1.5 oz./A + triclopyr 32.0 oz./A + crop oil concentrate at 0.5% v/v

Sept. 14: Pylex herbicide 1.0 oz./A + triclopyr 32.0 oz./A + crop oil concentrate at 0.5% v/v

Dates are approximate — applications should be made so that the final application is timed prior to the first frost. Yearly maximum of 4.0 oz. per acre of Pylex herbicide is allowed.

Controlling goosegrass: Make a single application to actively growing goosegrass at any growth stage at 1.0 to 1.5 oz./A + crop oil concentrate at 0.5% v/v.

Always read and follow label directions.
