Product Overview

Octane is a simple, economical solution to faster weed control.  Best applied on a sunny day, weeds sprayed with Octane show visual herbicidal symptoms within 24-48 hours.  Emerged weeds are quickly killed, helping in timely tournament prep or instant satisfaction by membership and greens committees.  Octane is also safe to use on recently seeded turf, being gentle on desirable cool- and warm-season turfgrass such as Kentucky bluegrass, perennial ryegrass, tall fescue, bermuda grass, centipede grass, St. Augustine and zoysia grass.

Tough on weeds, gentle on the environment

With Octane, show your customers the results they want, when they want them.  Octane takes out the toughest broadleaf weeds, delivering visual results within 24 - 48 hours of application. 

Octane's active ingredient, pyraflufen-ethyl, has an in-soil half-life of less than 24 hours, ensuring rapid in-soil breakdown following application.  Octane is rain-fast within an hour, delivers outstanding results with little active ingredient per acre,  has low water solubility and low vapor pressure, reducing potential off-target movement and its effect on the environment.

Application Instructions

Applied Alone. For Best Results:

  • Apply Octane at rates of 1 to 4 fl. oz./acre for control of seedling, non-mature winter and summer annual weeds and/or for temporary burndown of weeds listed on Control Spectrum page.
  • Tank-mixing Octane with other broadleaf herbicides may be needed for control of larger winter and summer annual weeds.

Applied in Tank-mix. For Best Results:

  • Apply Octane at rates of 0.7 to 1.5 fl. oz./acre in tank-mix combinations with herbicides registered for use such as amines, esters, and salts of 2,4-D, chloroprop, dicamba, mecoprop, triclopyr, fluroxypyr, and various combinations of these products for control of annual weeds and perennial weeds
  • Residual, long-term control of the target weeds is as defined by labeling of the companion product
  • For tank-mixing with herbicides, always read and follow the product label directions

Spray Volume Notes:

  • Octane is a contact herbicide that causes herbicidal symptoms only to plant parts that come into contact with spray applications
  • Proper spray volume and uniform coverage are important to maximize efficacy of Octane
  • Uniform sprays should be applied at 20 to 200 gal per acre (0.5 to 4.5 gal. per 1000 sq. ft.)
  • Higher spray volumes should be used to target whole weed population and/or weeds contained in dense turfgrass canopies

Use of Adjuvants Notes:

  • Addition of surfactants (spreaders/stickers) to the spray solution will improve efficacy and contact activity of Octane
  • Follow manufacturer’s use rates for specific sites
