DECIMATE "Weed & Grass Killer" is a non-selective herbicide that kills nearly all weeds and grass plus some woody plants. Glufosinate is a group 10 glutamine synthesis inhibitor that stops the conversion of two chemicals, glutamine and ammonia. The glutamine synthetase herbicides inhibit activity of glutamine synthetas, the enzyme that converts glutamate and ammonia to glutamine. This inhibition results in massive accumulation of ammonia in the plant which destroys cells and inhibits photosynthesis preventing energy production needed to support plant growth and development. It works by stopping the plant’s ability to utilize nitrogen and phosphorous causing the plant to produce more ammonia than it can tolerate and burns itself up.


Glufosinate is a contact herbicide, which means it doesn’t move down to the stems or roots of the plant. As opposed to Glyphosate which is a translocation herbicide, Glufosinate is more of a “localized contact herbicide” with little to no systemic action. It may only move up to 6 inches each direction in a large plant where applied. Again, no root uptake and no pre-emergent weed control.

This is a contact, semi-translocating herbicide that inhibits glutamine synthetase. Decimate works within 24 to 72 hours and works best when temps are over 85°. Rainfast in ½ hour to 4 hours. Soil may be reseeded or replanted after the spray has dried.
