Roadside Vegetation Control
Vanquish/VMD 480 can be used in a tank mix with glyphosate (356 g/L formulation) for annual vegetation control
on 1 - 2 metre wide roadside shoulders. Vanquish tank mixes with glyphosate and 2,4-D offer a broader spectrum of
total control of roadside vegetation. Apply to actively growing weeds between May and July at following rates:
Vanquish/VMD 480: 0.5 - 1.0 L/acre + glyphosate (356 g/L formulation): 0.3 - 0.4 L/acre or Vanquish/
VMD 480: 121 mL L/acre + 2,4-D amine 500: 485 mL/acre + glyphosate (356 g/L formulation): 0.3 - 0.4 L/acre.
Application Information
How to Apply
:
Apply with ground equipment or by air.
Water volume
:
Ground: Turf weeds: 45 L/acre; Weeds: 45 - 90 L/acre; Brush: rate/1,000 L of water. Aircraft: 35 L/
acre minimum.
Application Tips
Thorough coverage of weed and wetting brush to the point of runoff are essential for control. Brush and trees over
2
metres should be cut and regrowth sprayed. Do not use on bentgrass. Do not rake, mow or water turf within 24
hours after treatment. 2,4-D ester tank mix may improve brush control, especially under drought stress. Tank mix
with 2,4-D (amine or ester) for control of a broader range of weeds. Avoid spraying if temperatures exceed 30°C, to
reduce risk of vapour drift. Avoid spraying onto soil over root system of desirable trees and shrubs. Thoroughly clean
application equipment after use.
How it Works
Dicamba is a systemic herbicide absorbed through roots or leaves and translocated in most plants. Disrupts the
metabolic and growth activities in the plant.
Expected Results
Excellent control of brush can be expected within a year of application. Effect on broadleaf weeds may be seen in
10 - 14
days with twisting and bending of main stem, cupping of leaves, increase in root size and increase in fibrous
roots.
Restrictions
Rainfall
:
Rainfall 4 hours after application will not reduce effectiveness.
Grazing
:
Do not permit lactating dairy animals to graze fields within 7 days after application. Do not harvest
forage or cut hay within 30 days after application. Withdraw meat animals from treated fields at least 3 days before
slaughter.
Environmental Precautions
Vanquish is toxic to aquatic organisms and non-target terrestrial plants. Do not apply directly to water or in areas it
can wash into water bodies.
Runoff
:
Avoid runoff from treated areas into sensitive aquatic and terrestrial habitats.
