NICOSH HERBICIDE is a wettable granule formulation to be mixed in water and applied postemergence to field corn in Eastern Canada for control of quackgrass and annual grasses.
NICOSH HERBICIDE is non-corrosive, non-flammable, non-volatile, and does not freeze.


 NICOSH HERBICIDE rapidly stops growth of susceptible species; typical symptoms usually appear within 5-7 days, but may not be noticeable for 2-3 weeks after application, depending on growing conditions and weed susceptibility.
 Warm, moist conditions following application promote the activity of NICOSH HERBICIDE, while cool and/or dry conditions may reduce or delay activity. Weeds hardened off by cold weather or drought stress may not be controlled.
 Rainfall within 2-4 hours after application of NICOSH HERBICIDE may reduce weed control.
 NICOSH HERBICIDE is a foliar applied herbicide that will not give residual control of grass or broadleaf weed seedlings that may germinate after application. Weed control may be reduced if the corn canopy has closed in over the weeds, intercepting the spray.
 Poor weed control or crop injury may result from applications made to plants under stress from:
 abnormally hot or cold weather
 environmental conditions such as drought, water-saturated soils, hail damage or frost
 disease, insect or nematode injury
 prior herbicide, or carryover from a previous year's herbicide application.
 Delay application until stress passes and both weeds and corn resume growth. If corn has been injured by frost, wait 48-72 hours before applying NICOSH HERBICIDE. Severe stress conditions immediately following application may also result in crop injury or poor weed control.
 Ensure that the boom is set at the proper height in relation to the corn plants to apply NICOSH HERBICIDE accurately and uniformly, and to AVOID excessive application into the corn whorl.

• Do not re-enter treated fields until 12 hours after application.
• Apply only when the potential for drift to areas of human habitation or areas of human activity (houses, cottages, schools and recreational areas) is minimal. Take into consideration wind speed, wind direction, temperature, application equipment and sprayer settings.

Spray application:
• DO NOT apply during periods of dead calm. Avoid application of this product when winds are gusty. DO NOT apply with spray droplets smaller than the ASAE medium classification.
• DO NOT apply by air.
Buffer zones:
Use of the following spray methods or equipment DO NOT require a buffer zone: hand-held or backpack sprayer, inter-row hooded sprayer, spot treatment, soil drench, and soil incorporation.
The buffer zones specified in the table below are required between the point of direct application and the closest downwind edge of sensitive terrestrial habitats (such as grasslands, forested areas, shelter belts, woodlots, hedgerows, pastures, rangelands, and shrublands).
