It is February with a soil temp of 35. I have dead weeds (mostly crab grass) that I can see from the previous year throughout my yard. Since the weeds are up and visible but not actively growing will this still help prevent them from growing this year if used per the label? Is there another product that will work better?
The Anderson's 0.48 Barricade Herbicide will only prevent any seeds that are in the soil from emerging when applied before germinate. Any dead weeds should really be raked up/removed from the area for better lawn health. The general rule for spring is to apply your pre-emergent herbicide treatment 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 lawn/area. You will want to measure the temperature of the soil a few inches below ground.
