  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

  45. BARE GROUND • ONESTEP 1 QT ONESTEP+OUST EXTRA • BARE GROUND LESS MORE • HERBS MORE LESS • WOODY LESS MORE • RUBUS MORE LESS SUMMARY & CONCLUSIONS OCTOBER

  46. SUMMARY & CONCLUSIONS • STARTING THE ROTATION WITH DIFFERENT COMPETITOR COMMUNITIES • ONESTEP+OUST EXTRA PROVIDED MORE BARE GROUND, RUBUS, AND HERB CONTROL THAN ONESTEP ALONE • NO VISIBLE HERBICIDE DAMAGE • EXCELLENT SURVIVAL AND HERBICIDE TOLERANCE FOR NOV & FEB PLANTED SEELDINGS • IN YEAR TWO A LARGER GLD WAS RECORDED FOR NOV THAN FEB PLANTED SEEDLINGS • ONESTEP+OUSTEXTRA COMBINATIONS FOR PREPARING LONGLEAF SITES FOR EARLY (NOV) AND LATE (FEB) PLANTING IS A VIABLE OPTION
