BASF - herbicide

For selective control of various broadleaf weeds in flax (including low linolenic acid varieties.)

DO NOT use in greenhouses.
Apply only when the potential for drift to areas of human habitation or areas of human activity such as houses, cottages, schools and recreational areas is minimal. Take into consideration wind speed, wind direction, temperature inversions, application equipment and sprayer settings.

Field sprayer application
DO NOT apply during periods of dead calm. Avoid application of this product when winds are gusty. DO NOT apply when spray droplets smaller than the American Society of Agricultural Engineers (ASAE) coarse classification. Boom height must be 60 cm or less above the crop or ground.

Surface runoff
To reduce runoff from treated areas into aquatic habitats, consider the characteristics and conditions of the site before treatment. Site characteristics and conditions that may lead to runoff include, but are not limited to, heavy rainfall, moderate to steep slope, bare soil, poorly draining soil (e.g. soils that are compacted, fine-textured, or low in organic matter such as clay).
Avoid applying this product when heavy rain is forecast.
Contamination of aquatic areas as a result of runoff may be reduced by including a vegetative strip (buffer zone) between the treated area and the edge of the water body.

The use of this chemical may result in contamination of groundwater particularly in areas where soils are permeable (e.g. sand, loamy sand and sandy loam soils) and/or the depth to the water table is shallow.

Buffer Zones
Use of the following spray methods or equipment DO NOT require a buffer zone: handheld or backpack sprayer and spot treatment.
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, riparian areas and shrublands), sensitive freshwater habitats (such as lakes, rivers, sloughs, ponds, prairie potholes, creeks, marshes, streams, reservoirs and wetlands) and estuarine/marine habitats.

Method of Application – Field sprayer (1)
Crop – Flax
Buffer Zones (metres) Required for the Protection of:
Freshwater Habitat of Depths:
Less than 1 m – 1
Greater than 1 m – 1
Estuarine/Marine Habitats of Depths:
Less than 1 m – 1
Greater than 1 m – 1
Terrestrial Habitat - 4

(1) For field sprayer application, buffer zones can be reduced with the use of drift-reducing spray shields. When using a spray boom fitted with a full shield (shroud, curtain) that extends to the crop canopy, the labelled buffer zone can be reduced by 70%. When using a spray boom where individual nozzles are fitted with cone-shaped shields that are no more than 30 cm above the crop canopy, the labelled buffer zone can be reduced by 30%.

Maximum Application Rates and Maximum Number of Applications

Maximum Rate for a Single Application (1) (g a.e. of MCPA/ha) – 875
Cumulative Maximum Rate per Season (g a.e. of MCPA/ha) – 875
Maximum Number of Applications per Year – 1

(1) Do not exceed the application rates listed in the Rate of Application section of this product’s label.

FLAXMAX herbicide should be diluted in water and applied by ground application equipment for the control of many broadleaf weeds including:
Canada thistle (1)
Common groundsel
Dandelion (2)
Flixweed (2)
Kochia (suppression) (2-4 leaf)
Annual sowthistle
Perennial sowthistle (top growth)
Volunteer sunflower
Volunteer rapeseed
Russian pigweed
Redroot pigweed
Scentless chamomile (2-4 leaf)
Shepherd’s purse (2)
Stinkweed (2)
Tartary buckwheat
Wild buckwheat
Wild mustard

(1) season long control; with some re-growth in the fall
(2) spring rosettes only

1.5 L/ha
Apply FLAXMAX herbicide at 1.5 L/ha for the control of light infestations of Canada thistle, lamb’s-quarters, wild mustard, volunteer sunflower and spring seedlings (2-4 leaf) of flixweed, shepherd’s purse and stinkweed.

2.0 L/ha
At 2.0 L/ha, weeds controlled include the above plus medium to heavy infestations of Canada thistle, common groundsel, dandelion (spring rosette), kochia (suppression) (2-4 leaf), annual sowthistle, perennial sowthistle (top growth), redroot pigweed, Russian pigweed, scentless chamomile (2-4 leaf), smartweed, tartary buckwheat, volunteer rapeseed and wild buckwheat. Best results are obtained when FLAXMAX herbicide is applied to actively growing weeds in the 1-4 leaf (seedling) stage and when Canada thistle is between 10 cm and up to but not including the early bud stage. Poor weed control may result under cool or dry conditions.

Apply to the flax when the crop is 5-15 cm tall. Early spraying will reduce the risk of crop injury. Apply FLAXMAX herbicide in 100-150 L/ha total spray volume by ground equipment at spray pressures of 200-275 kPa. For optimum spray coverage, use flat fan nozzles tilted 450 forward to ensure better coverage.
NOTE: Some delay in maturity and crop injury may result from the use of the high rate but any potential yield reductions will usually be more than offset by increased yields due to better weed control.

Add half the required amount of water to the spray tank, then add with agitation the required amount of FLAXMAX herbicide. Add the balance of the water and continue to agitate while spraying.
The use of flood jet or hollow cone nozzles is not recommended, because of uneven and inadequate spray coverage. Ensure thorough and uniform spray coverage over the entire leaf area of the target weeds.

SENSITIVE PLANTS: Do not apply FLAXMAX herbicide directly to, or otherwise permit it to come into contact with sunflowers, legumes, fruit or vegetable crops, flowers or other desirable broadleaf plants and take precautions to avoid spray mists drifting onto them.
CROP ROTATION: Fields previously treated with FLAXMAX herbicide can be seeded to wheat, barley, oats, rye, corn, flax, canola, sugarbeets, mustard or should be summerfallowed. Do not seed to crops other than those listed above for at least one clear year following treatment.
GRAZING STATEMENT: Do not graze treated fields of flax within less than 7 days.
STRESS CONDITIONS: When weeds are stressed due to drought, flooding or prolonged hot or cool temperatures (150C or less), control can be reduced or delayed since weeds are not actively growing. Weed escapes may occur under prolonged stress conditions or low fertility. Do not make applications to weeds stressed longer than 20 days due to lack of moisture as unsatisfactory control can result.

1. Use coarse sprays at low pressures (200-275 kPa).
2. Use 100-200 L/ha of spray solution.
3. Spray when the wind velocity is 16 kmph or less.
EQUIPMENT CLEAN-UP: Equipment used to apply FLAXMAX herbicide should not be used to apply other pesticides to sensitive crops without thorough cleaning.

TOXIC to aquatic organisms and non-target terrestrial plants. Observe buffer zones specified under DIRECTIONS FOR USE.

For resistance management, FLAXMAX herbicide is a Group 4 herbicide. Any weed population may contain or develop plants naturally resistant to FLAXMAX herbicide and other Group 4 herbicides. The resistant biotypes may dominate the weed population if these herbicides are used repeatedly in the same field. Other resistance mechanisms that are not linked to site of action, but specific for individual chemicals, such as enhanced metabolism, may also exist. Appropriate resistance-management strategies should be followed.
To delay herbicide resistance:
Where possible, rotate the use of FLAXMAX herbicide or other Group 4 herbicides with different herbicide groups that control the same weeds in a field.
Use tank mixtures with herbicides from a different group when such use is permitted.
Herbicide use should be based on an IPM program that includes scouting, historical information related to herbicide use and crop rotation, and considers tillage (or other mechanical), cultural, biological and other chemical control practices.
Monitor treated weed populations for resistance development.
Prevent movement of resistant weed seeds to other fields by cleaning harvesting and tillage equipment and planting clean seed.
Contact your local extension specialist or certified crop advisors for any additional pesticide resistance-management and/or integrated weed-management recommendations for specific crops and weed biotypes.
