Armada® 800WG is a proven generic competitor to Preside®1. It is a cloverfriendly herbicide, for the control of many difficult-to-control broadleaf weeds. Armada will control or suppress broadleaf weeds in crops or pasture while selectivity to clovers and lucerne and chicory is preserved. Armada maximises crop establishment and production, by controlling many key problem weeds – including: Chickweed, Fathen, Shepherds purse, Sorrel, Spurrey, Stinking mayweed, Buttercup (annual and perennial), Mallow, Willow weed.


Apply to weeds in active growth. Do not apply in cold, wet conditions. Always apply Armada herbicide in mixture with a suitable spraying oil.

30 Chickweed, Spurrey, Wild Radish, Hedge Mustard. Apply before 4th leaf. Apply before 4th leaf.
50 Amaranthus (Redroot), Cleavers, Black Nightshade, Fathen, Shepherd's Purse, Mallow. Apply before 4th leaf.
50 Annual Buttercup, Creeping Yellow Cress, Yellow Gromwell. Apply before flowering.
65 Larger Weeds (above). -
65 Stinking Mayweed, Wireweed, Sorrel. Apply to young seedlings.
65 Field Pansy, Henbit, Willow Weed, Oxeye Daisy. Apply to young seedlings. Suppression only.
65 Giant Buttercup Apply before flowering.

Mature Pasture: Armada herbicide may be applied in either spring or autumn for buttercup control. Repeat spring treatments for two successive seasons will maximise control of giant buttercup.

Application Timing:

New pasture New and established White clover Apply after the emergence of the 4th trifoliate leaf and before stolon elongation.
New and established red and subterranean clover Apply after the emergence of the 6th trifoliate leaf and before stolon elongation.
Established lucerne Apply before flowering.
Maize Apply at the 4th leaf (900mm plant height) stage.
New and established chicory Apply after the emergence of the 4th leaf.

Application: Make sure that spray equipment is correctly calibrated. Ensure complete spray coverage for best results. Do not overspray.

Aerial and ground broadcast application: apply Armada herbicide in 100-300 litres of water per hectare. Use the higher water rate where weeds are dense.

CDA application: use the large (250-300 micron) droplet size and apply not less than 30 litres of water per hectare. Trials indicate that CDA application may result in less effective weed control than conventional boom spraying.

Compatibility: The addition of MCPB herbicide to Armada herbicide will increase the range of broadleaf weeds controlled. Also compatible with most commonly used herbicides.

Withholding Periods: Do not graze crops or treated pasture for 14 days after treatment. Do not plant susceptible crops (see below) for three months after treatment.

Crop Rotation:Do not plant susceptible crops until three months after application of Armada herbicide. Susceptible crops include all brassica species, sunflowers, lupins and beans. Do not allow spray to drift onto susceptible crops or land to be planted with susceptible crops.

Armada 800WG is registered pursuant to the ACVM Act 1997, Approval No. P7617
