No you should not reapply Pylex Herbicide at this time. Just follow the label instructions for your turf type and what you are treating for. You should not ever apply more then 0.46 oz per 1,000 sq. ft. per application or 0.092 fl. oz. per 1000 sq. ft. per year.
Pylex Herbicide will kill both Bermuda and Goosegrass. Revolver Herbicide is a post-emergent herbicide that selectively removes cool-season grasses from warm-season grasses. It is labeled to remove Goosegrass from Bermuda Grass.
The only information regarding using Additives/Surfactants with Pylex Herbicide is that non ionic surfactants may not provide satisfactory weed control with the Pylex and that a crop oil or MSO Surfactant is suggested so if the MSO was left out, the results with just the Pylex just might be less satisfactory.
If repeat applications are required for weed control, as long as you do not exceed the maximum rate for the weeds you are targeting per the Limitations and Restrictions Section on the product label, a follow up application with Pylex + MSO (Duo Stick Methylated Seed Oil) could be done.
At the 0.046 fl oz per 1000 sq ft rate:
DO NOT apply more than 2.0 fl oz per acre per application.
At the 0.0.92 fl oz per 1000 sq ft rate:
DO NOT apply more than 4 fl oz per acre per year.
DO NOT apply more than THREE times per season.
