Herbicides
Expected Results
The young leaves turn yellow within 5 - 10 days, and some grass species develop a reddish coloration. Necrotic spots
then form on the leaves, followed by death. An easy method of detecting whether the treatment has taken effect at an
early stage is whether the youngest leaf can be easily pulled out of the leaf sheath. The time required for complete
control is normally 7 - 21 days following treatment, depending on growing conditions and crop competition.
Control of quackgrass develops more slowly than control of annual grasses. Equinox EC herbicide is translocated
through the quackgrass plant to the rhizomes and kills actively growing rhizome buds, as well as above ground
vegetation. Dormant rhizome buds will remain unaffected by the spray, and regrowth can occur from these buds.
When Equinox EC herbicide is applied according to label directions, the regrowth of the quackgrass will not be
significant until 6 - 8 weeks after treatment, depending on growing conditions, crop cultivation practices and crop
competition.
