DIRECTIONS FOR USE

Use MCPA AMINE 500 Herbicide for controlling most broadleaved weeds in wheat, barley, rye, oats and corn, flax (do not use on low linolenic acid varieties), peas and forage legumes (alfalfa, bird’s-foot trefoil, red clover, ladino clover, alsike clover), turf (fairways and lawns), asparagus, pasture, rangeland, grasses, spruce seedling and noncrop/industrial sites. MCPA AMINE 500 Herbicide is a selective foliage broadleaf weed killer. It is absorbed through the leaves or roots and is readily translocated in the plant.
At recommended rates, MCPA persistence in the soil is up to one month in most growing conditions and up to 6 months in drier climates.

LINSEED FLAX (Do not use on low linolenic acid varieties): Treat flax with MCPA AMINE 500 Herbicide from the time when flax is 5 cm tall or is in the true-leaf stage to just before buds begin to form. Apply when crop is small to reduce shock. Apply as soon as there is enough weed emergence to make spraying practical. Apply the lower rate for susceptible weeds when weeds have 2 to 4 leaves and are growing rapidly. Use the higher rates for more resistant weeds, advanced weed growth, dry or cold weather conditions, or poor or slow growth. Better control of hempnettle, horsetail, smartweed, and wild buckwheat will result from two treatments of 0.7 L each. Apply first treatment then one week later follow with a second treatment starting when weeds are in the 2-leaf stage. Rates higher than 0.85 L may cause injury to crop.

OATS: Oats are more tolerant to MCPA than 2, 4-D and should be treated with MCPA AMINE 500 Herbicide unless resistant weeds are present. Spray when weeds are present. Treatments can be made from emergence up until the flag-leaf stage. If treatment is necessary between the 3 and 6 leaf states, use the lowest rate shown for cereal crops.

WHEAT, BARLEY AND RYE: MCPA AMINE 500 Herbicide is used for control of susceptible weeds in wheat and barley. Treatments can be made from the 3-leaf
expanded to the early flag leaf stage, and again from the milk stage to the full maturity.
Treatment made between emergence and 3-leaf stage may cause some crop injury but are less likely to with MCPAAMINE 500 Herbicide than 2,4-D. Fall-sown cereals: Treat in spring when crop starts growth and until the flag-leaf stage.

PEAS: Field and canning peas should be treated with MCPA AMINE 500 Herbicide when 10 - 18 cm tall, using not less than 150 L of water/ha. This treatment is not recommended for Nova Scotia.

SMALL GRAINS UNDERSEEDED WITH A LEGUME: MCPA AMINE 500 Herbicide may be used on grain interplanted with alfalfa, (except early maturing varieties), red clover, ladino clover and alsike. Do not use on grain interplanted with sweet clover or birdsfoot trefoil. Spray with not more than 0.35 - 0.70 L/ha when legumes are at about the second true leaf stage.

FORAGE LEGUMES (ALFALFA AND BIRDSFOOT TREFOIL) (direct and underseeded): The use of MCPA AMINE 500 Herbicide at 70 mL/ha (0.07 L/ha) and
CALIBER 625 (1.25 L/ha) provides better control of wild mustard plants beyond the four-leaf stage of the mustards. This tank mix may increase crop stunting.
For established legumes, a maximum of 2 applications is permitted per season, with a minimum retreatment interval of 90 days.

ASPARAGUS: Treat asparagus with MCPA AMINE 500 Herbicide following a cultivation just before first spears appear. Use 3.75 L/ha. Treatment may be repeated at end of cutting season.
For asparagus, a maximum of 2 applications is permitted per season with a minimum retreatment interval of 21 days.

CORN (FIELD, SWEET): Use MCPA AMINE 500 Herbicide at the rate of 0.55 L- 1.7 L depending on susceptibility of the dominant weeds in 200L of water per ha. In order to determine which group different weeds fall into, refer to the first column in the Dosage Chart for Flax, Cereals and Peas above.
For hand harvesting of corn (field and sweet), re-entry is not permitted until 15 days after application. As such, a preharvest interval (PHI) of 15 days after application is required.
Apply as an overall POSTEMERGENCE TREATMENT spray up until corn is 15-18 cm tall after which a directed spray should be used up until corn is 45 cm in height. Use the lower rate 0.55 L- 1.1 L for susceptible weeds having 2 to 4 leaves and growing rapidly. Use the higher rate 1.1 L- 1.7 L when weeds are at a more advanced stage of growth or if soil conditions are dry therefore causing slow growth, or if area is heavily infested with weeds. Avoid cultivation for 2 to 3 weeks following spraying. In case of drought, delay spraying until one week following rain. Consult cannery for susceptibility of sweet corn since some varieties may be injured when taller than 15 cm or rates exceed 0.55 L per ha.
Field corn should not be sprayed later than 3 weeks before tasseling. Higher rates than 1.1 L may cause severe injury to crop but this is usually offset by better weed control.
