Fall Weed Management Opportunity: Targeting Perennial Broadleaves in Cereal Stubble
By: Drew Thompson, TSA Eastern Canada
Fall conditions often lead to cereal stubble fields greening up. This regrowth includes volunteer cereals, but also a flush of weeds—among them, troublesome perennial broadleaf species.
While their presence is unwelcome, late summer and fall present an ideal window for controlling perennial weeds. As the season winds down, these plants shift their energy toward building root reserves in preparation for overwintering and regrowth in spring. This biological process creates a unique opportunity: by applying a systemic herbicide now—one that translocates throughout the plant and targets actively growing meristematic tissues—you can disrupt this cycle and reduce weed pressure in future crops.
INVOLVE® 50 WDG (tribenuron-methyl) meets the requirements listed above, and as such is a strong option for fields with perennial broadleaves (ie. dandelions and thistles). Mobile in the xylem and phloem, the ai is most active in meristematic tissues1. INVOLVE 50 WDG inhibits the ability of the growing points to form amino acids, including those in the rhizomes of the roots, impairing the ability of those weeds to grow and challenge subsequent crops.
Ideal for managing perennial broadleaf weeds such as dandelions and thistles, INVOLVE® 50 WDG is also tank-mix compatible with glyphosate and Group 4 herbicides (e.g., 2,4-D or dicamba), offering flexibility and additional modes of action in your fall weed control program.
