When should you apply pre emergent herbicide?
The best time to apply is the when the daytime highs drop to the mid-70s for about three to five days in a row. Since a pre-emergent application will not last through the following summer, make a pre-emergent application late spring or early summer (see Spring Herbicide Applicaiton map).Click to see full answer.

Furthermore, can you apply pre emergent too early?As long as you are early enough, as mentioned before, there is no harm in getting the pre emergent down way ahead of time. It just might wear out too soon to get the later batch of weeds if you start too early. Much of the information will apply to broadleaf weeds as well as the crabgrass concern that is emphasized.Secondly, should I mow before applying pre emergent? A good rule of thumb is only apply pre-emergent herbicides to lawns more than a year old. Since pre-emergent herbicide must be washed into the soil to be effective, you can mow before applying it, however you should wait a few days after application to mow again. In respect to this, what is the best pre emergent herbicide? The Best Pre-Emergent Herbicides: Prodiamine (Barricade equivalent) is the longest-lasting, and most economical due to lowest application rates. Isoxaben (Gallery equivalent) prevents a very large list of Broadleaf Weeds. Oxadiazon (Ronstar equivalent) is a great granular option – safe in all turf and ornamentals. Does pre emergent kill existing weeds?Important: Pre-emergent is not designed to control existing weeds or weed seeds. The weed will only be killed when it begins to sprout from the seed and hits the herbicide barrier. It is possible for seeds to remain dormant and not be harmed by the pre-emergent herbicide application.
