For bermudagrass control, the label for Pylex states for "control of these species requires a tank mix with triclopyr ester at 32 fl ozs/A" so if I am applying Pylex at the rate of "0.023 to 0.030 fl oz/1000 sq ft (0.7 to 0.9 mL) on a 3 to 4 week spray interval, how much Triclopyr Ester do I add? 32 fl ozs/A is equal to 30ml/1000 sq ft?
Bermudagrass is extrememly difficult to eliminate completely and even advised on the product label may take multiple years/seasons to control depending on the level of bermudagrass you are trying to eradicate. The recommended rate of Triclopyr Ester at 32 fl oz/per acre is equal to 0.73 fl oz per 1000 sq ft. A MSO (Methylated Seed Oil Surfactant) is also recommended in the tank mix with Pylex at the rate of 0.16 to 0.48 fl oz per gallon of water. For selective control of bermudagrass in cool season turfgrass, the Pylex Herbicide offers 2 treatment plans on page 10 of the product label: Option 1: Make 3 applications at 3 week intervals of Pylex at 1.3 fl oz/acre (0.023 fl oz/1000 sq ft) + MSO Surfactant at 0.16 to 0.48 fl oz/gallon of water + Triclopyr Ester at 0.73 fl oz/1000 sq ft. OR Option 2: Make 2 applications at 3 to 4 week intervals of Pylex at (0.03 fl oz/1000 sq ft) + 0.16 to 0.48 fl oz/gallon of water + Triclopyr Ester 0.73 fl oz/1000 sq ft with a follow up application 3 weeks later of Pylex at 1 fl oz/acre (0.02 fl oz/1000 sq ft) with 0.16 to 0.48 fl oz/gallon of water MSO and Tricolpyr at 0.73 fl oz/1000 sq ft
