Soil active herbicides are a great addition to any weed management program. By reducing weed pressures early on, crops can get off to a strong start in the spring. With different active ingredients and application timings, soil active herbicides can help tackle troublesome resistant weeds and slow down the development of herbicide resistance.<\/p>\n

Canada currently ranks third in the world \u2013 behind only Australia and the United States \u2013 for cases of herbicide resistance. This means farmers in western Canada should plan their herbicide application strategy around managing resistance.<\/p>\n

While we can\u2019t prevent herbicide resistance, we can slow resistance development, so it\u2019s important we adhere to good stewardship practices<\/a>. Soil active herbicides are an excellent addition to a resistance management strategy.<\/p>\n

How soil active herbicides work<\/strong><\/p>\n

Valtera<\/a>\u2122 and Fierce<\/a>\u00ae <\/sup>are two soil active herbicide options in the Nufarm portfolio that can help slow down weed resistance. They can be applied with a field sprayer in the fall after harvest and just before freeze up or soon after spring thaw. Valtera and Fierce provide up to eight weeks of early season control after activation helping your fields stay clean as you seed your crops.<\/p>\n\"\"\n

Once sprayed, the herbicide sits on top of the soil. It activates and moves into the soil water solution with moisture from snowmelt (if applied in fall) or spring rainfall (if applied in spring). The herbicide remains effective in the soil water solution for up to eight weeks providing a layer of protection just below the soil surface. As weeds germinate and grow through the soil layer, they come into contact with the herbicide molecules in the soil water solution. Both Valtera and Fierce help eliminate tough-to-kill weeds before they have a chance to get established and compete with your crops.<\/p>\n

Add Valtera and Fierce to your resistance management toolbox<\/strong><\/p>\n

Valtera and Fierce provide extended weed control after activation to help manage early or late flushing weeds that have adapted their growth cycle based on historical practices. Remember weeds are smart and like routine, so changing up your application timing is one way to help slow resistant and adaptive populations.<\/p>\n\"\"\"\"\n\"\"\"\"\n

Fierce and Valtera contain unique active ingredients for residual early season control. Valtera contains flumioxazin (Group 14) to manage broadleaf weeds like chickweed, kochia, lamb\u2019s quarters, pigweed and many more, while Fierce features flumioxazin (Group 14) and pyroxasulfone (Group 15) for control of both broadleaf and grass weeds like green foxtail and wild oats (suppression). These products provide additional options that allow farmers to rotate herbicide groups and fight tough weeds in their fields.<\/p>\n

Protecting fields early in the season with unique active ingredients can help make in-crop herbicide applications more effective and preserve their longevity. Weeds that germinate and escape in the spring will generally be smaller, less competitive, and more susceptible to an in-crop herbicide application. This helps reduce the amount of weed seed set back into the seedbank for future years. Reducing the overall weed population also means more moisture and nutrients for crops during critical growth stages and less green material during harvest.<\/p>\n

So, if you have some challenging weeds, and you haven\u2019t already started, it\u2019s time to change it up with a soil active herbicide application in the fall or early in the spring before seeding.<\/p>\n
