How much water do you mix with a 500 gram package of Drexel Diuron 80 Herbicide for pineapples?

Answer:

 HI-Apply 2 to 6 pounds of Drexel Diuron 80 Herbicide   per acre as a broadcast spray just before or immediately after planting but prior to weed emergence. Use 2 to 4 pounds per acre after harvesting the plant crop or ratoon crop (for first ratoon crop as well as subsequent ratoon crops) but before differentiation. For plant crop only, additional broadcast or interspace applications may be made prior to differentiation at 2 pounds per acre at intervals of not less than 2 months. Additional applications to plant crop may be made as needed to interspace only using 2 pounds per acre. Do not apply more than 12 pounds per acre as broadcast sprays nor more than 16 pounds total per acre per plant crop. Treated areas may be planted to pineapple or sugarcane 1 year after last application.
