DIRECTIONS FOR USE
IMPORTANT
PRODUCT DESCRIPTION:
NC-00439 Herbicide provides control of certain broad-leaved weeds in summerfallow, as a post-harvest treatment and on fields to be planted to wheat (spring, durum and winter) and spring barley. NC-00439 Herbicide contains two active ingredients formulated as dry flowable or water soluble granules. It is noncorrosive, non-flammable, non-volatile and does not freeze. NC-00439 Herbicide is to be applied as a uniform broadcast spray using water as a carrier. APPLY WITH GROUND EQUIPMENT ONLY.
Warm, moist growing conditions promote active weed growth and enhance the activity of NC-00439 Herbicide by allowing maximum foliar uptake and contact activity. Weeds hardened off by environmental stress such as cold weather, drought stress or excessive heat may not be adequately controlled or suppressed, and regrowth may occur. NC-00439 Herbicide may only be applied using ground spray equipment. For best results, ensure thorough spray coverage of target weeds.
NC-00439 Herbicide rapidly stops growth of susceptible weeds. However, typical symptoms (discoloration) of dying weeds may not be noticeable for 1 to 3 weeks after application, depending on growing conditions and weed susceptibility. Degree of control and duration of effect depend on weed sensitivity, weed size, spray coverage and growing conditions. Activity of the herbicide mixture may be delayed by cold, dry conditions after application.
DO NOT APPLY NC-00439 HERBICIDE WITH A CARRIER OTHER THAN WATER OR ANY ADDITIVE OTHER THAN THOSE INDICATED ON THIS LABEL. Other carriers may accelerate breakdown of this product and reduce its effectiveness.
DO NOT apply by air.
Field sprayer 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 American Society of Agricultural Engineers (ASAE) medium classification. Boom height must be 60 cm or less above the crop or ground.

CONTROL OF BROADLEAF WEEDS AND GRASSES PRE-SEED TO WHEAT (SPRING, DURUM OR WINTER) AND SPRING BARLEY, IN SUMMERFALLOW AND POST-HARVEST
With any summerfallow or post-harvest treatment, allow at least 10 days to elapse between treatment and tillage.
Only weeds emerged at time of application will be controlled. Weeds must be actively growing at time of application or control may be reduced.
Fields treated with NC-00439 Herbicide can be seeded to wheat (spring, durum or winter) or spring barley a minimum of 24 hours after application.
Apply NC-00439 Herbicide at 17.5 grams per hectare, tank mixed with glyphosate (present as potassium salt, isopropylamine salt, ammonium salt or trimethylsulfonium salt) and adjuvant (where required) in a total spray volume of 55-110 L/ha.
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 inversion, application equipment and sprayer settings.
