PRODUCT INFORMATION


HARMONY GRASS is a systemic, post-emergence herbicide with a built in adjuvant system for the selective control of wild oats, volunteer (tame) oats, green foxtail, yellow foxtail, barnyard grass, Persian darnel and volunteer canary seed in all types of spring wheat and Durum wheat. Do not use HARMONY GRASS on barley, as crop injury will occur. Do not apply this product using aerial application equipment except under conditions specified on this label.
HARMONY GRASS is absorbed by the leaves and is rapidly translocated to the growing points of leaves and stems. Thorough coverage of the plants is essential for consistent control. Actively growing susceptible grasses stop growing within 48 hours of treatment. Depending on species, growing conditions and crop competition, leaves and growing points turn yellow within one to three weeks after application. Further colour changes and loss of vigour will be observed, followed by a browning and complete control three to five weeks after application.
Although HARMONY GRASS does not control broadleaf weeds, HARMONY GRASS can be tank-mixed with a range of broadleaf herbicides to provide broad spectrum weed control in wheat. It can also be tank mixed with Decis Flowable Insecticide and MATADOR 120EC Insecticide to control grassy weeds and insects and with TILT 250E Fungicide to control grassy weeds and cereal leaf diseases. See section entitled “TANK MIXES of HARMONY GRASS WITH BROADLEAF WEED HERBICIDES, INSECTICIDES AND FUNGICIDES” and refer to the appropriate Tank Mix section for ground and aerial application.

DIRECTIONS FOR USE


When a tank mixture is used, consult the labels of the tank-mix partners and observe the largest (most restrictive) buffer zone of the products involved in the tank mixture.
DO NOT apply this product directly to freshwater habitats (such as lakes, rivers, sloughs, ponds, prairie potholes, creeks, marshes, streams, reservoirs and wetlands), estuarine/marine habitats.
To reduce runoff from treated areas into aquatic habitats, avoid application to areas with a moderate to steep slope, compacted soil, or clay.
Avoid application when heavy rain is forecast.
Contamination of aquatic areas as a result of runoff may be reduced by including a vegetative strip between the treated area and the edge of the water body.
DO NOT contaminate irrigation or drinking water supplies or aquatic habitats by cleaning of equipment or disposal of wastes.
CROPS: Spring Wheat and Durum Wheat
HARMONY GRASS can be used on all varieties of spring wheat and Durum wheat. Observe minimum interval to harvest of 60 days after treatment.
Do not apply on barley or any crop other than Spring Wheat or Durum wheat, as crop damage will result. Do not allow spray to drift to adjacent fields seeded to crops other than spring wheat or Durum wheat.
Do not treat wheat underseeded to forages. Observe a minimum of three (3) days before grazing livestock on crops treated with HARMONY GRASS.
For use directions specific to application by air, please refer to sections on aerial application. For aerial application precautions, please refer to the precautions section.
