Nicosulfuron 40SC herbicide is a suspension concentrate used at a rate of 0.6 - 2.4 fI oz per acre for selective postemergence grass weed control in field corn. Do not apply to popcorn or sweet corn. Do not make more than two applications of Nicosulfuron 40SC per cropping season. The combined dosage of sequential applications must not exceed 2.4 fl oz of Nicosulfuron 40SC per acre.

Many crops are highly sensitive to Nicosulfuron 40SC. All direct or indirect contact (such as spray drift) with crops other than field corn should be avoided (see also SPRAY DRIFT MANAGEMENT). For all application systems. use 50-mesh or larger strainer screens.
Do not apply Nicosulfuron 40SC through any type of irrigation system.

Broadcast Application
• Use a minimum of 15 gallons of water per acre (15 GPA) for best performance. Use a minimum of 10 gallons of water per acre (GPA) for light. scattered stands of weeds.
• For best performance. select nozzles and pressure that deliver MEDIUM spray droplets. for example. as indicated in nozzle manufacturers catalogues and in
accordance with ASABE Standard S572.1. Nozzles that deliver COARSE spray droplets may be used to reduce drift. provided spray volume is increased to
maintain coverage on small weeds. For optimal product performance and minimal spray drift. adjust the spray boom to the lowest possible spray height recommended in manufacturers' speCifications.
• Ensure that equipment is set up to avoid applying an excessive rate directly over the rows and into the corn plant whorl. This is most likely to occur when a nozzle is positioned directly above the row.
• Overlaps or starting, stopping, slowing, and turning while spraying may result in crop injury.

Band Application
For band applications. use proportionately less spray mixture. and carefully calibrate the band applicator to not exceed the labeled rate. Carefully follow the manufacturer's instructions for nozzle type (flat fans). orientation, distance of nozzles from the crop and weeds. spray volumes. calibration and spray pressure.

In New York State and California aerial application is not permitted. Use nozzle types and arrangements that will provide optimum spray distribution and maximum coverage at a minimum of 3 GPA.
Do not apply during a temperature inversion. when winds are gusty. or when conditions favor poor coverage and/or off-target spray movement.

Injury to or loss of desirable vegetation may result from failure to observe the following:
• Do not apply Nicosulfuron 40SC or drain or flush application equipment on or near desirable trees or other plants, or on areas where their roots may
extend, or in locations where the chemical may be washed or moved into contact with their roots.
Do not use on lawns, walks, driveways, tennis courts, or similar areas.
• Prevent drift of spray to desirable plants.
• Do not contaminate any body of water.
• Thoroughly clean application equipment immediately after use. (See the Sprayer Cleanup section of this label for instructions.)
• Do not graze or feed forage, hay, or straw from treated areas to livestock within 30 days of Nicosulfuron 40SC application.
