2. Bayer Innovation for Selective Weed Control
Esplanade 200SC
Superior pre-emergent broadleaf and grass weed control where warm season turf grass is desired. Outstanding residual control means less weed seed production and less mowing. Unique MOA.
Method 240SL
Both pre and post emergent control of many broadleaf weeds at very low use rates.
Derigo
Combination of 3 Ai and very low use rates for weed control in warm season grass roadsides with plant growth regulation and seed head suppression for Bahia grass.

3. Bayer Innovation in Timing
Prescription Calendar

4. Esplanade 5 oz./ac + Glyphosate 13 oz./ac + Surf.
Oct. 25 – Nov. 25, 2017 application
Dutton district

5. Good Economic Information
I-59 Guard rails for one ALDOT district
27.88 miles string trimming cost $16,000 (about $475/ac.). This can be done up to 3 times/year.
Substituted one (1) fall Esplanade 5 oz./ac + Glyphosate 13 oz./ac with labor/equipment cost = $1,550 (Used 1.32 gallons of Esplanade 200SC)
Maintained weed control and line-of-sight for the entire year without the need for string trimming.

6. Cable Barrier and Guardrail Treatment Comparisons (ALDOT)
It would take 17 years of annual weed trimming to break even comparing the cost of the concrete pad installation
It would take 53 years of annual Esplanade applications to break even comparing the cost of the 1 year of line trimming.
It would take 875 years of annual Esplanade applications to break even comparing the cost of the concrete pad installation.
(Comparing 5 ft. wide swath for 1 mile)

12. “The most dangerous job in our district is mowing and string trimming on the interstate. Not just dangerous for us, but for the public also.” Doug Hicks, District Superintendent

13. MOWING VS HERBICIDES Photo taken: August 2016
Mowed 7 times in 2016
3/13, 4/4, 4/20, 5/4, 5/20, 6/19, 7/18
NO HERBICIDES
Last mowed in October of 2015
HERBICIDES APPLIED IN FEBRUARY AND AGAIN IN MAY

14. Benefits If planned and managed properly the District should:
Reduce the interaction between mowers and the traveling public (increased safety)
Reduce mower damage to slopes and appurtenances
Have mowing funds that can be spent elsewhere in the District
Have labor to redirect to other District needs
Estimates ranged from 5 to 7 weeks for a 5 man crew
Increase the appearance of the District roadsides and, over time, see an increase in the District condition assessment scores

15. “24 ounces in 24 Months” No Mechanical Mowing DOT Roadside tour
Esplanade 5 oz/ac + Perspective 2 oz/ac treatment October 2015
Follow up with Derigo 2 oz/ac + Perspective 2 oz/ac May 2016
Esplanade 5 oz/ac + Method 240SL 3.2 oz/ac October 2016
Follow up with Derigo 2 oz/ac + Method 240SL 3.2 oz/ac May 2017

16. DOT District Fall Esplanade + Method
Replaced 7,000 gal. of diuron
Derigo + Method in early summer
16 counties went from 2 mowings to 1
