Water volume
: 22.5 - 45
L/acre.
Mixing Instructions
Use mixing instructions “b” on page 13.
Application Tips
Effectiveness may be reduced if spray mixture remains in the tank for more than 24 hours. Injury to pulse crops may
occur on coarse-textured soils, low in organic matter (less than 3%), or in fields with variable soils, gravely areas,
sandy areas or eroded knolls. Avoid planting pulse crops in soils containing more than 50% sand.
How it Works
Absorbed by foliage and roots, inhibits cell elongation.
Expected Results
Express SG stops the growth of susceptible weeds immediately. However, typical symptoms (discolouration) of
dying weeds may not be noticeable for 1 - 3 weeks after application, depending on growing conditions and weed
susceptibility. Degree of control and duration of effect depend on weed sensitivity, weed size, spray coverage and
growing conditions.
Restrictions
Rainfall
:
If rain occurs soon after application, control may be reduced; 1 hour of dry weather is needed to allow
Express SG to be absorbed by weed foliage.
Pre-harvest interval
:
Do not apply within 70 days of harvest for ExpressSun® sunflowers.
Re-cropping
:
A minimum recropping interval of 2 months should be left between the application of Express SG and
seeding of the next crop. The following crops can be seeded two months after application of Express SG herbicide:
canola, flax, lentils.
Environmental Precautions
Overspray or drift to important wildlife habitats such as shelterbelts, wetlands, sloughs or dry slough borders, or
woodlots should be avoided. Do not contaminate irrigation water. Toxic to aquatic organisms.
Toxicity
Very low acute mammalian toxicity. Acute oral LD
50
(
rats) = >5,000 mg/kg. May irritate eyes, nose, throat and skin.
Storage
Store in a cool, dry place.
