Avadex MicroActiv Herbicide

Herbicide layering (using a pre-emergent herbicide prior to an in-crop herbicide application) is a recommended way to help manage herbicide resistance. Avadex® MicroActiv is an ideal choice for a base layer in a wild oat herbicide-resistance management program. As a Group 8 herbicide it will control all wild oats including those resistant to Groups 1 and 2.

TIMING OF WILD OAT REMOVAL

Reduced early-season weed pressure allows more flexibility with the timing of the post-emergent herbicide application.

PRE-EMERGENT YIELD ADVANTAGE

Any early-season competition from wild oats will reduce yields, even with as few as three plants per square metre (Ag Canada, Lacombe). The photo below shows how Avadex allows your crop to grow with reduced competition, avoiding the 11% and 23% yield losses when wild oats are removed at the 2–3 or 4–5 leaf stage.

USE IN MIN-TILL FIELDS

MicroActiv technology establishes a continuous herbicide barrier in any field, including those under minimum or zero tillage. Now, all growers can profit from the resistance management and no-leaf stage wild oat control benefits of Avadex.

REGISTERED CROPS

Barley, canary seed, canola, durum wheat, flax, mustard, spring wheat, sugar beets

WEEDS CONTROLLED

Wild oats (including Group 1 and Group 2 resistant biotypes)

ACTIVE INGREDIENT

Triallate – Group 8 – thiocarbamate

FORMULATION + PACKAGING

10% granular MicroActiv available in 451.3 kg minibulks or 22.7 kg bags

SYMPTOMOLOGY

Wild oats will grow through the treated layer, absorb the active ingredient through shoot material and not emerge. 

CROP ROTATION

Do not seed oats the following year. All other crops can be grown the year after application.

APPLICATION TIPS

  • Use of a properly calibrated Valmar or floater is essential. 
  • Fall application should take place when the average soil temperature at a depth of 5cm is 4°C or less and within 3 weeks of soil freeze up. This situation generally occurs by October 1 across Western Canada.
  • Spring application should take place a minimum of 10 to 14 days before seeding.
  • A single heavy harrow pass is sufficient for incorporation in minimum or zero-till fields. Two passes are recommended in conventional-till fields.
