Weeds and Staging

Registered Tank Mixes
Tank mix partner
Pyramin + tank mix partner rate
Remarks
Nortron
Pyramin: 2.12 L/acre + Nortron: 1.48 L/acre
Apply one application per year, prior to weed emergence.
Application Information
With
:
Ground equipment. Do not apply by air.
Water volume
:
See above. Rates for row spacing and band width are variable.
Incorporation
:
Pre-plant - incorporate shallow. Fall ridging - apply Pyramin in a 17.5 cm band and cover with a
15 - 20
cm high ridge of soil. In the spring, level the ridges and leave guide marks to enable planting the bands.
Avoid levelling deeper than the chemical placement.
Application Tips
Pyramin must not be mixed into soil deeper than seed is planted to reduce beet injury.
How it Works
The active ingredient in Pyramin is absorbed by the roots and is translocated to the leaves.
Expected Results
If adequate moisture is present, the weeds will fail to emerge. If the soil is dry for a long time, weeds that emerge and
become well established will not be fully controlled, but small emerged weeds may die back, once adequate moisture
is present.
Restrictions
Rainfall
:
No effect.
Grazing
:
The tops of beets grown in Pyramin-treated soil may be used for human consumption or fed to livestock.
Re-cropping
:
None.
Environmental Precautions
Do not apply Pyramin to aquatic organisms and terrestrial plants. Do not apply within 5 metres of sensitive terrestrial
habitats and 1 metre of sensitive aquatic habits.
Runoff
:
Avoid contamination of aquatic areas and sensitive terrestrial habitats as a result of runoff by including a
buffer strip between the treated area and the sensitive areas.
Leaching
:
Avoid application where soils are permeable (e.g. sandy soil) and/or the depth to the water table is
shallow.
Drift
:
Care should be taken to avoid drift onto sensitive plants such as rapeseed and mustard.
Toxicity
Oral - Low toxicity. Acute oral LD
50
(
rats) = > 2,369 mg/kg.
Storage
Store in a cool, dry place. Do not store below 0°C.
