RECOMMENDATIONS FOR ANNUAL BLUEGRASS CONTROL

WITH ARROW 2 EC HERBICIDE IN ORNAMENTALS

RECOMMENDATIONS FOR PERENNIAL GRASSES

• Apply only to actively growing grasses at recommended weed heights.

• Apply when the first grass weed species in a mixed grass weed population reaches the recommended

growth stage for treatment.

• Use the high rate under heavy grass pressure and/or when grasses are at maximum height.

(1) 8 fl. oz./A = approximately 0.2 fl. oz./1000 sq. ft.

(2) 16 fl. oz./A = approximately 0.4 fl. oz./1000 sq. ft.

• Add non-ionic surfactant containing at least 80% active ingredient at the rate of 1 pt. per 50 gals. (0.25% v/v).

ANNUAL BLUEGRASS

(Poa annua)

to 4-leaf 6 16

• Apply under favorable soil moisture and humidity which exists within a few days after rainfall or within 7

days after irrigation. Grass needs to be actively growing at time of application(s).

• Apply at weed stage indicated on the label, as reduced control can be expected with more mature annu-

al bluegrass.

• Use the high rate under heavy grass pressure and/or when annual bluegrass is more mature.

• Add a non-ionic surfactant containing at least 80% active ingredient at the rate of 1 pt. per 50 gals.

(0.25% v/v).
