GENERAL INFORMATION
This granular herbicide is recommended for wild oat and wild millet (green and yellow foxtail) control in spring and durum wheat, spring barley, rapeseed (including canola), flax (not including low linolenic acid varieties) and mustard only.
This product will also provide suppression of the following annual broadleaved weed species: lamb’s quarters, kochia, redroot pigweed, Russian thistle and wild buckwheat. Other crops should not be treated with this product as injury may occur.
This product should be applied according to the recommendations on this label. See the
"Directions For Use" section for additional information.
Application equipment must be properly calibrated. Application of an excessive rate of granular
Fortress Microactiv Herbicide may injure the crop, whereas application of too low a rate may result in poor weed control. Before applying this product, be sure the soil is in good working condition.
Clay soils may require additional tillage to obtain good tilth. Application to a field which is wet, lumpy, rough or ridged will result in reduced weed control and promote crop thinning. See the
"Field Preparation" section for additional information.
The initial incorporation of this product into the soil must be completed within 24 hours after application, except for the Fall surface treatment. For Fall surface guidelines, see the “Fall
Treatment (surface)” section of this label. The incorporation should not be deeper than 5 cm as deeper incorporation tends to dilute the product, thus decreasing weed control and increasing the risk of crop injury. See the "How To Incorporate" section for additional information.
When using granular Fortress Microactiv Herbicide, an untreated strip should be left for proof of results. Wild oat control may be evaluated by removing a surface 2.5 to 5 cm of soil at the time of germination to inspect the number of wild oats that were killed before emergence. This product is primarily absorbed by wild oat shoots from the treated layer of the soil. Wild oats are usually controlled before they emerge through the soil. Occasionally, and particularly under dry conditions and/or cool soil temperatures, some wild oats may emerge and reach the 3 to 4 leaf stage before dying. Wild Millet seedlings will generally be controlled as they germinate.
Rainfall of at least 1.5 cm within 2 weeks after seeding in the spring is required to ensure maximum performance.
Under conditions of prolonged cool soil temperatures at the time of germination, or extreme drought in spring, this product may not maintain the usual high standard of weed control.
