1 Site Preparation Study One Step/Oust Mixtures Drs. Jimmie Yeiser and Rick Williams, Stephen F. Austin State University and University of Florida

2 INTRODUCTION OUST EXTRA IS A PRE-MIX BLEND OF OUST XP AND ESCORT XP OUST XP A COMMON PART OF THE FALL SITE PREPARATION TANK MIX ESCORT XP IS NOT LABELED FOR THE PREPARATION OF LONGLEAF PINE SITES CAN LONGLEAF PINE SITES BE SAFELY PREPARED WITH FALL- APPLIED OUST EXTRA MIXTURES FOR PRE-PLANT WOODY PLANT CONTRL AND POST-PLANT HERBACEOUS WEED CONTROL?

3 OBJECTIVE TO COMPARE: ONESTEP AND ONESTEP PLUS OUST EXTRA MIXTURES WHEN PREPARING LONGLEAF SITES FOR: WOODY PLANT SITE PREP CONTROL, RESIDUAL, POSTPLANT HERBACOUS WEED CONTROL, PLUS LONGLEAF PINE TOLERANCE AND PERFORMANCE
