2014 Cotton Update For Growers • Brake F2
Section 18 Submitted: Brake F2 • EPA should approve or reject by March • Mixture of fomesafen (Reflex) & fluridone • 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
Brake PRE: Worst Injury Seen • Pic of reflex vs Brake in dry
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
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)
Brake F2 • Projected cost for 1 pt/acre: • Volume purchasedCost/A • 40-80 acres -- $40.62 • 120-160 acres -- $38.42 • 200+ acres -- $34.58
Rainfall: Two rains each <0.25 in Reflex + Warrant Fluridone
Brake F2 When Activated Brake F2 Non-treated
2014 Cotton Update • Brake F2 • Changes in burndown
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
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
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!!!

Conventional Tillage Cotton Systems. 2013. SPLIT REFLEX SYSTEM Most effective and safest program that exist!
RR Reduced Tillage Cotton Systems. 2014. APPLY VALOR AND/OR DIREX TO EVERY ACRE; ADD GRAMOXONE IF PIGWEED UP!!!
RR Reduced Tillage Cotton Systems. 2014. 1. Reflex rate of 12 oz. 2. Warrant rate 3 pt/A. 3. Direx rate 10 to 24 oz/A 4. Include burndown herbicide.
Diuron PRE: 1 Complaint 2013 Select a rate of diuron that gives you 7 to 10 d control.
Diuron + Warrant vs Reflex + Warrant Diuron + WarrantReflex + Warrant Length Control: At least 1 wk more Palmer Control: Very GoodExcellent/Consistent Timely POST : CriticalCritical but less Injury Potential: LowerHigher Cost: LowerHigher Hand weeding: Slightly more Resistance Mgmt: Less on PPO
RR Reduced Tillage Cotton Systems. 2014. If using Liberty/Roundup system and planning on using Liberty; Liberty POST 1 is almost always correct timing
RR Reduced Tillage Cotton Systems. 2014. Add Envoke, Aim or ET if morningglory is issue. Suprend + MSMA just as effective.
Calendar RR Weed Program (POST applications based on days after planting) Intervals influenced by: • Palmer biology • Thrips insecticide application • Avoiding topical herbicide applications after 7 leaf cotton.

2014 Cotton Update • Brake F2 • Changes in burndown • Tank mix kit • Weed program • Time of day influence herbicides • Rye system
Using Heavy Rye Covers For Sustainability Rye Cover Weedy Cover
Economic Analysis Completed • Seven LARGE ON-FARM Studies • Cadillac Rye Program about $40 per acre higher cost.
Potential Benefits for Georgia Growers • Improved Palmer control • Reduce herbicide input over time • Protect herbicide chemistry • Less labor (compared to tillage) • Mitigate wind and water erosion • Moisture conservation • Likely higher yields on dryland • Possibly reduce irrigation • Reduces Thrips damage • Likely reduce impact from ryegrass and horseweed.

2014 Cotton Update • Brake F2 • Changes in burndown • Tank mix kit • Weed program • Time of day influence herbicides • Rye system • 2,4-D and Dicamba tolerant cotton
2,4-D and Dicamba Technologies • 2016??? Maybe some in 2015??? • Major hurdles = Endangered Species Act and managing off-target movement. • Major benefits = Increased flexibility • Summit in Spring with Commissioner of Ag
