Should I reapply Prodiamine 65 WDG (Generic Barricade) if I forgot to water it in?

I decided to go with Three split applications of Prodiamine 65 this year. I applied my first treatment as my soil temperature began to approach 55F. It’s been over a month without any rain and I realized that I forgot to water in the product. My current soil temperatures are slowly approaching 60F and weeds are beginning to sprout. Is it safe to reapply this product now and should I adjust my other split applications because of this? My St. Augustine is still dormant at this stage.


Ideally, Prodiamine 65 WDG should be watered in within 7 days of application.You should reapply if it has been longer than one week. Be sure that you do not exceed the annual maximum amount of product for your type of turfgrass.

The application timing of Prodiamine 65 WDG will vary according to the exact weeds you are targeting and your specific region. We recommend contacting your local extension office to confirm the right application timing for your area. We do have a Lawn Care Schedule on our site with general time frames that may also be helpful.
