Glyphosate Resistant Ryegrass

Glyphosate Resistant Annual Ryegrass
An increasing amount of Resistant Annual Ryegrass has been seen. This shows up as ryegrass plants that have a reduced control or no control at all after they have been sprayed with glyphosate. You may notice several large stands of ryegrass that remain green and healthy.

If you are seeing this problem seek advice. It is important to stop this ryegrass from seeding and increasing next year. If you continue to use glyphosate and increase your rate of application you will only make the problem worse.

The only solution is to with other groups of herbicide, like Alliance (Combination of Amitrole and Paraquat), or grass selective herbicides (Fulisade).
