For Tall Fescue, will applying Barricade 4FL Pre-Emergent Herbicide (Prodiamine) at the 0.5 fl oz per 1000 sq ft rate give me the 4-5 month pre emergent control of listed weeds?

If I use 0.50 per 1000 sq feet Would this give me the 4 - 5 month preemergent control? 1. tank sprayer 2. per 1000 sq ft 3. Tall Fescue I'm reviewing the charts on pages 12 & 13 chart page 12 I see 21 for Tall Fescue Chart page 13 I see 0.5 - 1.1

Answer:

 Barricade 4FL Herbicide can be applied once or twice per year as long as you don't go over the 1.1 ounces per 1000 sq. ft per year(21 oz per acre/per year) for Turf Type Tall Fescue.  Doing a split application 60-90 days following the 1st application will give you longer residual control as opposed to a single application. We would recommend doing a second application at the 0.5 oz rate per 1000 sq ft to get the longer monthly residual. Please review the charts of page 12 & 12 of the product label for more information.
