Lowest temp Rezilon Pre Emergent Herbicide can be applied

Answer:

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.
