2. Warrant Ultra Herbicide 1.Mix of Warrant + fomesafen (i.e Reflex). 2.Label: preplant, PRE at-planting, & directed. 3. Monsanto literature: 48-70 fl oz 4. Suggest (38 oz)= 12oz Reflex + 2.2pt Warrant 5. Add ½ pt of Warrant for Roundup system.

3. Glufosinate Formulations - Cotton Slide from Prostko

4. 1.Section 18 2.New chemistry for agronomics. 3.Mix of fluridone and fomesafen (i.e. Reflex). 4.Apply PRE behind press wheel (~16 oz/A). 5.Very good for weeds, costly, watch carryover, systems approach required. Non-treatedBrake

5. 1.Similar chemistry as Dual and Warrant. 2.Minimal research in RR or RR/LL cotton. 3.Positioning for dicamba-tolerant cotton? 4.Overtop from 1 leaf – 2 nd wk of bloom. 5.Label: up to 21 oz/A; suggest 12-16 oz/A.

6. 1.Similar chemistry as Dual and Warrant. 2.DIRECTED application after 7-leaf cotton. 3.Label: 0.75 to 1.5 oz/A; suggest 0.75-1 oz/A mixed with Direx + MSMA for longer and better residual control.

7. 1.Valor + Zidua 2.PRECISION DIRECTED, 18+ inch, bark! 3.Label: 3 oz/A 4.Mix with MSMA or Roundup……very good but can be hot stuff.

21. Auxin Systems Compared to Today: 1.Weed control better, lower herbicide and hand weeding input costs (not much easier). 2.Crop injury (cotton) more complex. 3.Off-target movement more complex

22. Auxin Systems 1.Clean at planting 2.Two Residual PRE’s….. 3.Sequential POST’s…….. 4.Layby……

23. RU + dicamba 1 X 2 X Injury in a Challenging Environment (worst 10% of time?)

24. Layby……….critical to sustainability!! For Palmer: Direx + MSMA; add Envoke for morningglory. If grasses: Roundup + Direx; add Envoke for morningglory.
