º Fall Application:
º Applications of Avadex MicroActiv granules should be made to standing stubble. DO NOT apply to smooth,
hard packed soils that may allow granules to drift. If excessive crop residue exists at the time of application, a
vigorous harrowing prior to application should be conducted to ensure the granules are in good contact with
the soil. Apply when the soil begins to cool (less than 4 o C) and within 3 weeks of soil freeze-up. Incorporation
using harrow operation following application in the fall is recommended but can be performed in the spring
before seeding. Spring incorporation using harrow operation prior to seeding is recommended to optimize
control levels.
º Spring Application:
º Applications of Avadex MicroActiv granules should be applied and incorporated using harrow operation in
spring 10 to 14 days before seeding.
• Conventional Tillage Systems
º Fall Application:
º Apply Avadex Microactiv granules to fields that are in good working condition, without excessive crop residue.
Heavy crop residue or lumpy, wet fields may require tillage prior to application. Apply when the soil begins
to cool (less than 4 o C) and within 3 weeks of soil freeze-up. Only one incorporation is required in the fall. The
second incorporation may be done in the fall (before soil freeze-up) or in the spring.
º Spring Application
º Apply Avadex to fields that are in good working condition, without excessive crop residue. Heavy crop residue or
lumpy, wet fields may require tillage prior to application. Avadex applications require two incorporations, with
the second incorporation at right angles to the first. Using a seeder that provides soil disturbance equivalent to a
cultivator may replace one of the incorporations. The first incorporation should be completed within 48 hours of
application and the second incorporation should be delayed an additional 48 hours or more.
º The liquid formulation must be incorporated into soil that is free of lumps or crop residue. Liquid formulations
should be applied to fields with 30 percent or less residue cover. Heavy crop residue or lumpy, wet fields may
require tillage prior to application. The liquid formulation is recommended for spring use because soils are left
in an erosion prone state if the liquid is fall- applied. The first incorporation of the liquid formulation should be
completed as soon as possible after spraying, while the second incorporation may be done any time prior to
crop emergence.
º Ensure that cereals are seeded at least 1.25 cm (1/2 inch) below the treated layer.
How it Works:
Refer to Table 9 on page 48.
Effects of Growing Conditions:
Reduced control may result if prolonged cool conditions or dry soil conditions prevail at the time weeds are emerging.
If conditions are dry or wild oats germinate from below the treated zone, the weeds may emerge, but will usually be
controlled. Thinning of wheat can occur under conditions of heavy rainfall or if cold soil conditions persist as the crop
emerges.
DO NOT apply to fields where crop residue has been burned in the previous 12 months. Efficacy will be reduced.
Tank Mixes:
Herbicides: Avadex liquid may be tank mixed with liquid formulations of trifluralin for control of wild oats, green and yellow
foxtail in wheat and barley. Apply after seeding but prior to crop emergence. Consult the recommendations for trifluralin for
rates in different soil types.
Insecticides: None registered.
Fertilizer: Avadex Liquid EC alone, or tank mixed with liquid formulations of trifluralin, may be tank mixed with liquid
fertilizer. Compatibility of the herbicide and liquid fertilizer should be checked. Follow the instructions on the herbicide
label prior to adding the herbicide to the spray tank.
• Avadex Liquid EC may be sprayed on dry urea fertilizer. A minimum of 60 kg per acre (150 kg/ha) of dry urea fertilizer
must be used. Only commercial blending is recommended.
Note: The above mixes are those listed on the Avadex labels only.
