Spike® 80DF herbicide


Active Ingredient: tebuthiuron

Spike® 80DF herbicide is a dry-flowable formulation that is mixed and applied with a water carrier. A soil-active product, Spike 80DF is applied to the soil surface by ground equipment and enters plants only through the roots. Spike 80DF has the same active ingredient (tebuthiuron) as Spike 20P herbicide, a formulation applied as a pellet. Spike 80DF is labeled for two uses on range and pastureland:

Banded application method for use on rangeland and pasture. Spike 80DF herbicide is mixed with water and applied directly to the soil surface in a concentrated, narrow, straight stream (band). There, the solution enters the soil profile to intersect with the lateral roots of woody plants. Precise, banded applications of Spike 80DF herbicide are perfect for clearing susceptible brush from fencerows, to create openings for wildlife habitat, or to spot-treat brush motts (small groves or clumps of brush) to improve grazing. For more information on banded application download our Fact Sheet.

A tool to slow the advance of rangeland wildfires. Spike 80DF helps fight fires in more ways than one. Firebreaks created with Spike 80DF not only help slow down wildfires, they also provide access points for fire personnel, as well as areas for safety and parking emergency vehicles. To create herbicidal firebreaks, apply Spike 80DF herbicide from midsummer to early fall. Use truck- or tractor-mounted equipment. A spray boom with low-pressure, large droplet nozzles should be adjusted to deliver a uniform strip about 40 to 50 feet wide. Depending on application rate, one application can provide effective control for two years or more.
