b. ** Pounds of Toxicant per Acre and Pounds of Diluted Dust Per Acre**

number of pounds of toxicant per unit area (per acre or per 1,000 square feet), the

amount of diluted dust to be applied per unit area (in the same units) may be

determined as follows.

(1) Pounds of toxicant per unit area = pounds of diluted dust per unit area

X percent toxicant in diluted dust.

Lb toxicant/acre

Therefore: lb diluted dust/acre =

----------------- .

% toxicant

(2) Example: How many pounds of 5 percent dust are required per acre if

the recommended rate of application is 10 pounds of toxicant per acre?

10 lb toxicant/A

-------------------- = 200 lb diluted dust/A

0.05

c.

specify the number of pounds of toxicant per unit area, the amount of diluted spray in

gallons may be determined as follows.

(1) Pounds of toxicant per unit area = pounds of diluted spray (gal X 8.34

lb/gal) per unit area X percent toxicant in diluted spray.

lb toxicant/A

Then: gal diluted spray/A X 8.34 lb/gal =

--------------

% toxicant

lb toxicant/A

Therefore: gal diluted spray/A = ---------------------- .

% toxicant X 8.34 lb/gal

(2) Example: How many gallons of 6 percent emulsion are required per

acre if the recommended rate of application is 0.3 pounds of toxicant per acre?

0.3 lb toxicant/A

---------------- = 0.6 gal diluted spray/A

0.06 X 8.34 lb/gal
