Under low wild oat populations (<75 plants/sq metre), can use a lower rate of Simplicity at 150 mL/acre when mixed with these products.
Application Information
With
:
Apply with ground equipment or by air.
Water volume
: 20 - 40
L/acre ground or air application.
Mixing Instructions
Half fill tank with water and agitate. Add Tandem A, then Tandem B, then any tank mix partner; add non-ionic
surfactant, then finish filling tank.
Application Tips
Only weeds emerged at time of application are controlled. For optimum results, apply Tandem to actively growing
seedling weeds. Weed control may be reduced if Tandem is applied under stress conditions. Do not apply to crops
that are stressed as crop injury may result. Under conditions of low crop competition and high weed density or wet
foliage at time of application, control may be reduced.
How it Works
Tandem A 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. Tandem B is a plant growth regulator, which will cause twisting,
bending and erratic growth of susceptible weeds.
Expected Results
Tandem rapidly stops the growth of susceptible weeds. However, typical symptoms (discolouration) of dying
weeds may not be noticeable for 1 - 3 weeks following application, depending on growing conditions and weed
susceptibility. Degree of control and duration of symptoms depend on weed sensitivity, weed size, crop competition,
growing conditions following treatment and spray coverage.
Restrictions
Rainfall
:
Rain within 4 hours of application may reduce control.
Grazing
:
Livestock may be grazed on treated crops 7 days following application.
Pre-harvest Interval
:
Do not harvest the treated crop within 60 days after application.
Re-cropping
:
Eleven months following an application of Tandem, the following crops can be seeded: barley, brown
mustard, canola, dry bean (of the species Phaseolus vulgaris), flax, canola quality Brassica juncea, lentils, oats, field
peas, chickpea, spring wheat, soybean and yellow mustard, sunflowers or summerfallowed.
Environmental Precautions
Simplicity is toxic to aquatic organisms and non-target terrestrial plants. Avoid contamination of these sensitive areas
by using the recommended buffer of 1 metre from water bodies and 2 metres from sensitive terrestrial areas.
