Tridem A Herbicide is a selective postemergence herbicide for the control of wild oats and certain broadleaved weeds in spring wheat, durum wheat and winter wheat not underseeded with legumes.
Tridem A Herbicide is mixed with water and applied as a uniform broadcast spray. It is non-corrosive, nonflammable, and nonvolatile.
Tridem A Herbicide must be applied early postemergence, to the main flush of actively growing wild oats and broadleaved weeds. Conditions favouring active weed growth enhance the activity of Tridem A Herbicide by allowing maximum foliar uptake and contact activity. Weeds hardened off by cold weather or drought stress may not be adequately controlled or suppressed and re-growth may occur. For best results, ensure thorough spray coverage of target weeds. See “DIRECTIONS FOR USE” section of this label for complete use details.
Tridem A Herbicide stops growth of susceptible weeds rapidly. However, typical symptoms (discolouration) of dying weeds may not be noticeable for 1 to 3 weeks after application, depending upon growing conditions and weed susceptibility. Degree of control and duration of effect are dependent on weed sensitivity, weed size, crop competition, growing conditions at and following treatment, and spray coverage.
MODE OF ACTION
Tridem A Herbicide inhibits the production of the ALS enzyme in plants. This enzyme is essential for the production of certain amino acids which are essential for plant growth. Tridem A Herbicide is a Group 2 mode of action herbicide.
DIRECTIONS FOR USE
READ THE ENTIRE LABEL BEFORE USE. FAILURE TO FOLLOW LABEL INSTRUCTIONS MAY RESULT IN ERRATIC WEED CONTROL OR CROP DAMAGE. DO NOT APPLY TO CROPS UNDERSEEDED WITH LEGUMES.
As this product is not registered for the control of pests in aquatic systems, DO NOT use to control aquatic pests.
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) coarse classification. Boom height must be 60 cm or less above the crop or ground.
Aerial application: DO NOT apply during periods of dead calm. Avoid application of this product when winds are gusty. DO NOT apply when wind speed is greater than 16 km/h at flying height at the site of application. DO NOT apply with spray droplets smaller than the American Society of Agricultural Engineers (ASAE) coarse classification. To reduce drift caused by turbulent wingtip vortices, the nozzle distribution along the spray boom length MUST NOT exceed 65% of the wing- or rotorspan.
DO NOT contaminate irrigation or drinking water supplies or aquatic habitats by cleaning of equipment or disposal of wastes.
TRIDEM A HERBICIDE ALONE
Application Directions - Spring Wheat, Durum Wheat, and Winter Wheat
Apply Tridem A Herbicide at a rate of 52 g per hectare for control of low wild oat populations (<75 plants/m2) and control of Japanese brome††. Always add a non-ionic surfactant (Agral 90, Ag-Surf or Surf 92) at 0.25 v/v (0.25 L per 100 L of spray solution) when applying Tridem A Herbicide alone. Apply using aerial equipment or ground equipment that will assure uniform coverage. See table below for weeds species controlled. Tridem A Herbicide will control only emerged weeds. Weeds that germinate after application will not be controlled.
†† For control of Japanese brome from the 1 leaf to 4 leaf, 2 tiller stage under good growing conditions
Application Timing (Spring and Durum Wheat)
Apply to actively growing wheat from the 3 leaf stage to before the flag leaf stage. Apply when wild oats are actively growing at up to the 4 leaf, 2 tiller stage with population less than 75 plants/m2 and when Japanese brome is at the 1- to 4-leaf, 2 tiller stage under good growing conditions. Only weeds emerged at the time of treatment will be controlled. Best results are obtained from applications made to seedling weeds. Extreme growing conditions such as drought or near freezing temperature prior to, at or following time of application may reduce weed control and increase the risk of crop injury at all stages of growth.
Under conditions of low crop and high weed density, control may be reduced.
Application Timing (Winter Wheat)
Apply in the fall when winter wheat is in the 1-3 leaf stage or in the spring when winter wheat is in the 2-7 leaf, 4 tiller stage. For spring applications, apply when weeds are actively growing at the stages indicated. Only weeds emerged at the time of treatment will be controlled. Best results are obtained from applications made to seedling weeds. Extreme growing conditions such as drought or near freezing temperature prior to, at or following time of application may reduce weed control and increase the risk of crop injury at all stages of growth. Under conditions of low crop and high weed density, control may be reduced.
Occasionally slight yellowing or height reduction may be observed in the treated crop. These transient symptoms disappear within 14 days with no reduction to yield. Do not apply to crops suffering from drought, nutrient deficiency or exposed to frost or other agronomic factors affecting plant growth.
If foliage is wet at the time of application control may be decreased. Applications of Tridem A Herbicide are rainfast within 2 hours after application.
Livestock may be grazed on treated crops 7 days following application. Do not harvest the treated crop within 60 days after application.
