A shopper on Jun 26, 2018
BEST ANSWER: Its my understanding that the Johnson Grass needs to be between 18 - 24 inches tall. You need enough surface area for it to absorb the Outrider sufficiently. I sprayed about 3 gallons of this herbicide 30 feet out all around my barn as a test three weeks ago. Johnson Grass was 3 feet high in places. Its all now turning red and brown.

Very happy with the product.

Will Outrider kill tropical soda apple? And is Outrider a fast acting chemical?
John D on Jun 28, 2018
BEST ANSWER: The application rate for Milestone is 5–7 oz/A. The rate for GrazonNext HL is 1.5–2.1 pt/A.

Another option is to use triclopyr (Remedy Ultra, others). When using triclopyr, mow plants to a 3-inch stubble height as soon as possible to keep plants from producing fruit and seed. Repeat mowing when plants reach the flowering stage (50–60 days) through April. Fifty to 60 days after the April mowing, when plant regrowth is at the first flower stage (late May-June), spray triclopyr at 1 qt/A + 0.25% v/v non-ionic surfactant in 40 gal/A of water. Triclopyr does not possess soil residual activity, and follow-up applications to control escaped or new seedlings will be necessary.
