Rezilon Pre Emergent Herbicide is compatible with listed non-selective herbicides. For other products, we do recommend performing a jar test and test a small area as indicated on the label when tank mixing to determine compatibility.
The recommended seeding interval after applying Rezilon Herbicide is 18 months, regardless of turfgrass species. Since this is a pre-emergent herbicide, there will be residual product in the ground. Planting sooner than 18 months before application could inhibit seed germination.
Per the product label, bermudagrass and bahiagrass have excellent tolerance to Rezilon Pre Emergent Herbicide. The label recommends to only use it on other perennial warm season grasses if you have experience that indicates your zoysiagrass, in this case, is tolerant to this product. Without experience, the label advises to test a small area for tolerance first. Otherwise, you can use Dimension 2EW Herbicide instead, which is labeled to be safe on zoysiagrass. Please read the product label for complete application instructions.
Rezilon Pre Emergent Herbicide is a pre-emergent herbicide only and is safe on established wheat when used as directed on the product label.
Rezilon Pre Emergent Herbicide should not be used at the same time of seeding. You can only use on established bermuda grass. Per the product label: DO NOT apply to pastures or hayfields that have not been establies for at least one growing season.
The general rule for spring is to apply your pre-emergent herbicide such as Rezilon Pre Emergent Herbicide is after the ground has thawed from the winter but before the temperature of your soil reaches 55 degrees, as that is when crabgrass begins to germinate. Other weeds will germinate when the soil temperature is between 55 and 65 degrees. You can use a soil thermometer to determine the temperature of your area. You will want to measure the temperature of the soil a few inches below ground.
The ideal time to apply a fall pre-emergent herbicide is between August and November when the soil temperature is below 70 degrees and dropping.
You may contact your local cooperative extension office to determine the correct timing of the application as this will vary greatly from region to region or search online for best time to apply in (your area). A lot of universities have great articles for this.
