Chlorpyrifos CONDITION D <br /> Continued <br /> Determining Setback distances are for a broadcast application.When labels specify the <br /> application application rate as fluid ounces per 1000 feet of row or 100 feet of row,the <br /> rate- "broadcast equivalent application rate"is the rate of active ingredient(lbs <br /> Converting Al/ac)within the entire application block.The"broadcast equivalent <br /> row feet rate to application rate"must be calculated to determine the setback distance. <br /> lbs AY/ac <br /> Generalized formula converting fl oz per row feet to pints per acre <br /> (fl oz per 1000 row feet) (row width in inches) x 32.67* <br /> *32.67 is a factor combining several unit conversions,including uzches <br /> to feet,square feet to acres,and fluid ounces to pints.For rates <br /> expressed as fl oz/ 100 row feet,use 326.7 instead. <br /> Example—Lorsban Advanced <br /> • Label application rate for onions is 0.37 fluid ounces per 1000 feet of <br /> row, if the row spacing is 6 inches. <br /> • Pints/acre=0.37 x 32.67=6=2.01 pints/acre. <br /> • 2.01 pints/acre is converted to lbs Al/ac using the calculation above. <br /> Setback A setback distance must be established for every chlorpyrifos application near <br /> distances a sensitive site. The setback distance must extend outward from the perimeter <br /> of the sensitive site to the perimeter of the application block. <br /> Use the following application and rate specific setback distance tables for all <br /> chlorpyrifos applications. <br /> Aerial application—fixed wing or rotas <br /> Application Rate Occupied Sensitive Site <br /> (lbs AI/ac) Setback Distance(feet) <br /> <1 250 <br /> >1 —2.3 500 <br /> Ground applications <br /> Application Rate Occupied Sensitive Site Setback Distance(feet) <br /> (lbs Al/ac) Sprinkle Clremigation or ground boom Airblast <br /> <-1 150 150 <br /> >1 —2 350 350 <br /> >2—4 400 400 <br /> >4—6 prohibited 500 <br /> Continued on next page <br /> 3 <br /> Chlorpyrifos <br />
