Effects of Growing Conditions:
Prolonged drought conditions after a May-July application to fallow may result in higher levels of trifluralin in the soil at the
time of seeding.
Injury to flax, barley, wheat or lentil may occur if soil and weather conditions are not conducive to rapid crop emergence
(cold or dry soils at the time of seeding and crop emergence).
To minimize crop injury, seed into a firm, moist seed bed using a seeder with good depth control and on row packing. Plant
barley no deeper than 2 inches (5 cm). Plant cereals, lentil and flax no deeper than 1.5 inches (4 cm).
Less than acceptable weed control will result if dry conditions prevail at the time of weed emergence.
Rainfall has no direct effect on products’ activity. Flooding (3 to 5 days) will cause rapid breakdown of the product resulting
in reduced weed control. Flooding for 3 weeks or more will result in total breakdown of the product resulting in loss of
weed control.
Tank Mixes:
Herbicides:
• Soybeans:
º Sencor (Treflan Liquid EC only).
Fertilizers: Liquid product may be applied with liquid fertilizer as a carrier. Before the herbicide is added to the tank,
compatibility of the herbicide to liquid fertilizer should be tested following instructions on the herbicide container.
Trifluralin liquids may be blended with dry bulk fertilizers (DO NOT mix with nitrate fertilizers). Check label for blending
instructions.
Insecticides: None registered.
Fungicides: None registered.
Note: The above mixes are those listed on the Trifluralin labels only.
Adding ingredients in the correct order is critical for optimum performance. Check labels of products to be mixed for
directions. General guidelines can be found on page 8.
Restrictions:
• Rainfall: No restriction. Flooding may reduce weed control.
• Re-entry Interval: Wait at least 12 hours before entering treated fields.
• Grazing Restrictions: DO NOT graze the treated crops or cut for feed prior to crop maturity.
• Re-cropping Interval: Oat, canaryseed, and small-seeded grasses may be affected the year after treatment. Corn
is sensitive at higher rates of application. Damage to wheat can occur if the crop is seeded into land that has been
treated during the previous 21 months with trifluralin products and has received abnormally low amounts of
precipitation. Damage is worse if conditions are not conducive to rapid emergence of the wheat (for example, if the
crop is seeded deep or if soil conditions remain cool during emergence). Damage tends to be greater on fields treated
with granular formulations.
• Aerial Application: DO NOT apply by air.
• Storage:
º Granular formulations must be stored in a cool, dry location, out of sunlight.
º Rival EC: DO NOT store below 5°C.
º Treflan Liquid EC and Bonanza 480: DO NOT freeze. Crystallization of the active ingredient may occur at less than
5°C. To reconstitute, bring temperature to 15°C and shake well until no crystals are visible. This should be done
before adding to the spray tank.
