MAGNA Herbicide for a one-pass broad-spectrum weed management program in Glyphosate Tolerant corn. MAGNA Herbicide has both contact and residual activity. Following a post-emergent application of MAGNA Herbicide, emerged weeds take up the herbicide through treated foliage and cease growth soon after application. MAGNA Herbicide is also absorbed through the soil and/or by the foliage of emerging weeds.
GENERAL INFORMATION
MAGNA Herbicide contains three active ingredients for a one-pass broad-spectrum weed management program in Glyphosate Tolerant corn. MAGNA Herbicide has both contact and residual activity. Following a post-emergent application of MAGNA Herbicide, emerged weeds take up the herbicide through treated foliage and cease growth soon after application. MAGNA
Herbicide is also absorbed through the soil and/or by the foliage of emerging weeds. Complete death of the weeds may take up to 2 weeks. MAGNA Herbicide provides residual control of newly emerging susceptible weeds through root and shoot absorption. MAGNA Herbicide has a high level of crop safety in Glyphosate Tolerant corn.
USE DIRECTIONS – FIELD CORN:
WARNING: APPLY MAGNA HERBICIDE ON GLYPHOSATE TOLERANT CORN VARIETIES ONLY
NOTE: ALWAYS USE PEDIGREED (I.E. CERTIFIED) GLYPHOSATE TOLERANT CORN SEED. CORN WHICH IS NOT DESIGNATED AS GLYPHOSATE TOLERANT WILL BE
DAMAGED OR DESTROYED BY THIS TREATMENT.
Apply MAGNA Herbicide at 4.2 L per hectare in a spray volume of 100 - 200 L and a minimum pressure of 206 kPa (refer to the “MIXING AND SPRAYING INSTRUCTIONS” section of this label) for post-emergent weed control from the spike up to and including the 6 leaf stage of Glyphosate Tolerant corn. A non-ionic surfactant such as AGRAL 90 at 0.2% v/v may be added.
For best results, apply MAGNA Herbicide to actively growing weeds that are less than 15 cm in height. For protection of the corn crop’s yield potential, apply MAGNA Herbicide before the start of the critical period of weed control. When Glyphosate Tolerant corn is grown under no-till conditions, a burndown weed control
application may still be required prior to a MAGNA Herbicide application.
MIXING AND SPRAYING INSTRUCTIONS:
The use of urea ammonium nitrate (UAN) will result in crop injury and reduced grass weed control and is not recommended with MAGNA Herbicide.
GROUND APPLICATION ONLY:
Water Volume:
Apply in 100 – 200 litres per hectare. When weed foliage is dense, use a minimum 140 litres per hectare.
Spray Pressure:
206 – 300 kPa
Spray Nozzles:
Flat Fan with 50 mesh or larger screens. For uniform coverage and increased penetration of the crop canopy, set the nozzles at a downward angle of 90 degrees (90°).
Surfactant:
Postemergent applications of MAGNA Herbicide may be applied with a non-ionic surfactant such
as AGRAL 90 at 0.2% v/v (2.0 L for each 1000 L of spray mixture).
Mixing Procedure:
1. Ensure that the sprayer is totally clean.
2. Fill the sprayer half full with water. Engage gentle agitation.
3. Ensure that the agitation system is working properly and that it creates a rippling or rolling action on the water surface.
4. Add the non-ionic surfactant if applicable (e.g., AGRAL 90) at 0.2% v/v.
5. Add MAGNA Herbicide and AATREX Liquid 480 Herbicide (if an applicable tank-mix) slowly and agitate until completely dispersed. To ensure complete dispersion, wait 2 or 3 minutes after the last of the herbicide has been added to the tank.
6. Continue agitation while completing the filling of the sprayer with water.
7. Always ensure that agitation is maintained until spraying is completed, even if stopped for brief periods of time.
8. If agitation is stopped for more than 5 minutes, re-suspend the spray solution by running on full agitation prior to spraying. MAGNA Herbicide must be sprayed the same day as mixing.
9. Do not mix, load or clean spray equipment where there is a potential to contaminate wells or aquatic systems.
