Section 18 Submitted: Brake F2

  • 1. EPA should approve or reject by March
  • 2. Mixture of fomesafen (Reflex) & fluridone
  • 3. Apply PRE 16 oz/A (8 oz Reflex + 0.2 lb Brake/A)

Section 18 Submitted: Brake F2

Positives:

  • 1. Fluridone is “new” effective chemistry
  • 2. Very good on pigweed when activated
  • 3. Minimal injury

  • Pic of reflex vs Brake in dry

Brake PRE: Worst Injury Seen

DO NOT APPLY OVER COTTON

slide-6

Section 18 Submitted: Brake F2

Negatives:

  • 1. Research suggest no more effective than

current programs (less injury though)

  • 2. Rest of weed program stays same
slide-7
SLIDE 7

Section 18 Submitted: Brake F2

Negatives:

  • 1. Research suggest no more effective than

current programs (less injury though)

  • 2. Rest of weed program stays same
  • 3. At least 0.6” if not 0.75” to activate
  • 4. Suggest rotate to cotton/peanut only currently

(there label more flexible but our data is concerning)

  • Projected cost for 1 pt/acre:

Volume purchased Cost/A 40-80 acres -- $40.62 120-160 acres -- $38.42 200+ acres -- $34.58

Plant Back Interval for Valor

Strip Till = can be applied 10 d ahead of

planting as long as strip till operation occurs between applying Valor and planting

slide-13
SLIDE 13

Plant Back Interval for Valor

Strip Till = can be applied 10 d ahead of

planting as long as strip till operation occurs between applying Valor and planting

No Till or when strip is run prior to spray = 1) <30% ground cover = 28 d + rain 1 inch 2) >30% ground cover = 21 d + rain 1 inch

slide-14

Plant Back Interval for Valor

Strip Till = can be applied 10 d ahead of

planting as long as strip till operation occurs between applying Valor and planting

No Till or when strip is run prior to spray =

1) <30% ground cover = 28 d + rain 1 inch 2) >30% ground cover = 21 d + rain 1 inch

NEW: If Reflex (generic) will be used PRE add 7 days to no-till planting intervals!!!

Diuron PRE: 1 Complaint 2013

Select a rate of diuron that gives you 7 to 10 d control.

slide-24
SLIDE 24

Diuron + Warrant vs Reflex + Warrant

Diuron + Warrant Reflex + Warrant Length Control: At least 1 wk more Palmer Control: Very Good Excellent/Consistent Timely POST : Critical Critical but less Injury Potential: Lower Higher Cost: Lower Higher Hand weeding: Slightly more Resistance Mgmt: Less on PPO

If using Liberty/Roundup system and planning on using Liberty; Liberty POST 1 is almost always correct timing

Add Envoke, Aim or ET if morningglory is issue. Suprend + MSMA just as effective.

(POST applications based on days after planting)

Intervals influenced by:

  • 1. Palmer biology
  • 2. Thrips insecticide application
  • 3. Avoiding topical herbicide applications

after 7 leaf cotton.

Potential Benefits for Georgia Growers

  • 1. Improved Palmer control
  • 2. Reduce herbicide input over time
  • 3. Protect herbicide chemistry
  • 4. Less labor (compared to tillage)
  • 5. Mitigate wind and water erosion
  • 6. Moisture conservation
  • 7. Likely higher yields on dryland
  • 8. Possibly reduce irrigation
  • 9. Reduces Thrips damage
  • 10. Likely reduce impact from

ryegrass and horseweed.

2,4-D and Dicamba Technologies

  • 1. 2016??? Maybe some in 2015???
  • 2. Major hurdles = Endangered Species Act

and managing off-target movement.

  • 3. Major benefits = Increased flexibility
