Spot Treatment
When using hand sprayers or high volume sprayers utilizing hand guns, mix 1/4% to 1/2% (0.33 oz. to 0.65 oz.
per gal.) Arrow 2 EC Herbicide and treat to wet vegetation while not allowing runoff of spray solution. For uses
requiring crop oil concentrate, include crop oil concentrate at 1% (1.3 oz. per gal.) by volume. For uses requiring
non-ionic surfactant, include non-ionic surfactant at 1/4% (0.33 oz. per gal.) by volume.
Note: If Arrow 2 EC Herbicide is applied as a spot treatment, care should be taken to not exceed the maxi-
mum rate allowed on a “per acre” basis or crop injury may occur.
CHEMIGATION
ONIONS (Dry Bulbs and Green) AND GARLIC
SPRINKLER IRRIGATION APPLICATION
Do not apply Arrow 2 EC Herbicide by chemigation in the states of Idaho, Montana, Oregon, and Washington.
This product may be applied to onions and garlic by sprinkler irrigation systems including center pivot, later-
al move, end tow, side (wheel) roll, travelers, big gun, solid set, or hand move. Do not apply by chemigation to
any other crop or to this crop using any other type of irrigation system.
Apply Arrow 2 EC Herbicide at the high rate recommended for annual grasses (16 fl. oz./A) when the grass
height is at the low end of the range (application to larger grasses may not provide adequate control). Add a
crop oil concentrate containing at least 15% emulsifier at 1 quart per acre.
Apply Arrow 2 EC Herbicide in 0.1 to 0.2 acre-inch of water either at the end of a regular irrigation set or as a
separate application not associated with a regular irrigation using the least amount of water that provides
proper distribution and coverage. Application of more than label recommended quantities of irrigation water
per acre may result in decreased product performance by removing the chemical from the zone of effective-
ness. Use a metering device to inject the Arrow 2 EC Herbicide into the irrigation water at a constant flow.
Constant agitation must be maintained in the chemical supply tank during the entire period of herbicide appli-
cation. Inject the product with a positive displacement pump into the main line ahead of a right angle turn to
ensure adequate mixing. Allow time for all lines to flush the herbicide through all nozzles before turning off
irrigation water. To ensure the lines are flushed and free of remaining herbicide, a dye indicator may be inject-
ed into the lines to mark the end of the application period.
It is not recommended that Arrow 2 EC Herbicide be applied through an irrigation system connected to a pub-
lic water system. Public water system means a system for the provision to the public of piped water for human
consumption if such system has at least 15 service connections or regularly serves an average of at least 25
individuals daily at least 60 days out of the year.
Use Precautions
1. Apply this product only through sprinkler irrigation systems including center pivot, lateral move, end tow,
side (wheel) roll, travelers, big gun, solid set, or hand move. Do not apply this product through any other
type of irrigation system.
2. Crop injury, lack of effectiveness, or illegal pesticide residues in the crop may result from non-uniform dis-
tribution of treated water.
