SIMAZINE 4L PLUS GRAMOXONE EXTRA TANK MIX COMBINATION FOR WEED CONTROL IN APPLES, PEACHES, AND PEARS .

SIMAZINE 4L plus Gramoxone Extra tank mix combinations are effective in apple, peach and pear orchards for killing existing vegetation and for residual control of the annual broadleaf and grass weeds listed under General Information. This combination is also effective for top kill and suppression of perennial weeds. Apply the rates shown in the following table as a tank mix in 50-200 gals. of water per acre to the orchard floor avoiding contact with fruit, foliage or stems. Apply when the weeds and grasses are succulent and the new growth is from 1-6 inches tall. Since Simazine enters weeds mainly through their roots, rainfall or irrigation is needed to move it into the root zone.
