Fortress MicroActiv Herbicide
French Label and SDS
The perfect base layer herbicide for canola, Fortress® has groups 3 and 8 to control wild oats, green foxtail* and yellow foxtail, and provide suppression of certain annual broadleaf weeds.
ROTATE TO GROUP 3 AND 8 HERBICIDES
Herbicide layering, or using a pre-emergent herbicide prior to an in-crop herbicide application, is a recommended way to use multiple modes of action to help manage
herbicide resistance. Add Fortress® as a base layer to your weed control program to reduce reliance on post-emergent herbicides and enhance your yields due to reduced early-season weed pressure. Fortress controls Group 1 and Group 2 resistant wild oats, too.
PRE-EMERGENT YIELD ADVANTAGE
This Gowan Canada study from 2016 shows how including Fortress can maximize yield with reduced early-season weed pressure. The level of weed control is similar for the Fortress + Liberty® and Liberty + Clethodim treatments, however, the yield of the program approach is higher. Reduced early-season weed pressure also allows more flexibility with the timing of the post-emergent herbicide application.
USE IN CONVENTIONAL, MINIMUM OR ZERO-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 Fortress.
Canola, flax, mustard, wheat (spring and durum), barley
Wild oats (including Group 1 and Group 2 resistant biotypes), green foxtail* (including Group 1 resistant biotypes), yellow foxtail
Kochia, lamb’s quarters, redroot pigweed, Russian thistle, wild buckwheat
Trifluralin – Group 3 – dinitroanaline, and Triallate – Group 8 – thiocarbamate
FORMULATION + PACKAGING
14% granular available in 453.6 kg minibulks or 22.7 kg bags
Wild oats will grow through the treated layer, absorb the active ingredient through shoot material and not emerge. Green and yellow foxtail are controlled as they germinate. Broadleaf weeds will have reduced populations and reduced vigour.
Do not seed oats, sugar beets, or small-seeded annual grasses such as timothy, canary seed grass, or creeping red fescue the following year.
Do not use for wheat if trifluralin has been used since June 1 of previous year.
- Use of a properly calibrated Valmar or floater is essential.
- Spring application should take place a minimum of 10 to 14 days before seeding.
- 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.
- A single heavy harrow pass is sufficient for incorporation in minimum or zero-till fields. Two passes are recommended in conventional-till fields.
*Does not include trifluralin-resistant green foxtail.
- Durum Wheat
- Spring Wheat
