Distinct herbicide provides an excellent broad spectrum and alternative mode of action product for use on broadleaf annual, winter annual and perennial weeds in the post-harvest use segment. Distinct combines two modes of action: dicamba, a Group 4 synthectic auxin and diflufenzopyr, a Group 19 that allows the weed control to glyphosate, resulting in cleaner fields in the spring and an effective herbicide resistance management strategy.
Here are some tips for the best results with Distinct applied in the fall:
- Apply in the morning or early afternoon, as plants need two to four hours of 10 degrees Celsius or greater for effective translocation of systemic herbicides like Distinct.
- Give weeds 1 or 2 days after frost before scouting to determine if herbicide applications are still available.
- Leaves of weeds should have >60% green after a frost event for effective uptake of herbicides. If more than 40% of tissue is dead due to frost, herbicides will be ineffective on weeds.
- Perennial weeds can tolerate some frost depending on temperatures leading up to the frost event. If daily temperature lows reach 5 degrees or lower for multiple days prior to the frost event, perennial plants “harden off” and may with stand frosts close to -10 degrees and still be effectively controlled with post-harvest treatments. Without these lead up temperatures, these plants can be dormant after a frost as light as -3 degrees, resulting in reduced control. Scouting for actively growing plants is vital prior to application.
Tank mixed with glyphosate, one case of Distinct will treat 40-80 acres, depending on rate (58-115 g/ac) and is supported with Merge or MSO applied at 200 ml /ac. Distinct applied at 80 ac/case prior to October 15 allows for all cereal and corn crops to be seeded the following spring. Applications prior to October 1 allows for all canola systems, soybeans, field peas, and lentils to be seeded the following spring. Applications prior to September 1, allow for all other unlisted crops to be planted the following spring. If higher rates of Distinct are used after September 1, rotate to cereal or corn crops only.
A fall application of Distinct herbicide in combination with glyphosate allows for effective management of weeds, including glyphosate-resistant weeds, and gives growers the best chance at starting with clean fields in the spring.
