Injury to crops may result if treated soil is washed, blown, or moved onto land used to produce crops. Exposure to [*] may injure or kill most crops. Injury may be more severe when the crops are irrigated. Do not apply [*] when these conditions are identified and powdery, dry soil or light or sandy soil are known to be prevalent in the area to be treated.

5 Impact of Fuel Prices on Budgets Fuel cost to maintain an 18-hole golf course ranges from $25,000 - $35,000 Estimate - 50% of fuel cost is for mowing fairways, tees, and approaches during active turf growth Bluegrass fairways are mowed an avg. of 4X / week for about 25 weeks Less mowing = fuel savings Kentucky bluegrass cemetery Assume 500 headstones (HS) per acre x 100 acres = 50,000 HS Approx. 31 seconds per HS to trim x 50,000 = 430 hours = 3 workers at 8 hrs/day for 18 days Assume 7 trims from April - Oct. Labor cost = 3 workers x 8 hrs/day x 18 days x $8.00/hr x 7 trims = $24,192 or $3456/trim Total labor time = 126 days/worker Additional labor is needed for mowing and other tasks Trimming Costs - No Primo MAXX Summary Plant growth regulators offer many benefits to turfgrass managers and ROADSIDE managers. While many of these are intangible savings, reducing fuel, labor, and machinery costs represent real cost savings.

Hillsborough County manages 6,500 acres of roadside rights of way. Mechanical mowing cost is $60.00 per acre. One mowing cycle costs $390,000. Six mowing cycles per year costs $2,340,000. One herbicide application/cycle (chemical mowing) costs $35.00 per acre and lasts up to six months before weed regrowth occurs. One chemical mowing round costs $227,500. Plan is to chemical mow twice a year (cost: $455,000) and mechanical mow twice a year (cost: $780,000). Annual cost savings of $1,105,000.!!! Labor/machinery reallocated. 12 weeks of seed head suppression to date since application Photo take 8/14/09 Hillsborough County, FL Chemical Mowing Program Advantages with Milestone VM Significant cost savings versus mechanical mowing only Improved labor efficiency reallocation Improved turf quality and aesthetics Reduced shoulder deterioration Improved safety less time on ROW, visibility Reduced customer complaints PERSONAL AND CONFIDENTIAL 6
