Zidua Herbicide

No other residual herbicide can control resistant pigweed like Zidua® herbicide. For the past several years, Palmer pigweed, waterhemp and other small-seeded broadleaf weeds and grasses have been growing resistant to glyphosate, ALS-inhibitor, ACCase and triazine herbicides. Zidua circumvents this resistance, providing growers with effective, long-lasting residual weed control.

How It Works

Ten years of research have culminated in the discovery of pyroxasulfone — the breakthrough active ingredient in Zidua. Pyroxasulfone is an isoxazoline, a new class of chemistry that delivers higher intrinsic activity and a broader spectrum of control of small-seeded broadleaf weeds and grasses.

Zidua acts to inhibit very long chain fatty acid synthesis as a Group 15 (WSSA) herbicide. It is a root-and-shoot growth inhibitor that controls susceptible germinating seedlings before or soon after they emerge from the soil.

Extensive field research demonstrates that Zidua provides superior residual control of resistant Palmer pigweed and waterhemp up to 10% better and up to three weeks longer than other preemergence herbicides such as dimethenamid-p, acetochlor or s-metolachlor.

Zidua is the only solo product of its kind, providing growers with unmatched application flexibility from fall through early preplant and early postemergence. Quite simply, growers can determine their own schedule for using this remarkable herbicide. Effective rates are eight to 10 times lower than current commercial standards with similar use patterns.

Zidua is also a perfect tank-mix partner for applications of Sharpen® herbicide, powered by Kixor® herbicide technology, for superior burndown and residual weed control.

Always read and follow label directions.

Problems Controlled

Zidua provides exceptional residual control of a broad array of weed species (see chart).  Zidua, when applied at recommended rates and timings, stays active in the soil during the critical crop production period to control weeds before or soon after they emerge and begin competing with the crop. One of the many advantages of Zidua is its long-lasting residual control, making it an important option for providing consistent and effective weed control.

With Zidua’s high level of residual activity, effectiveness on glyphosate-resistant weeds and broad-spectrum weed control, growers now have an excellent new tool to add to their weed-control systems for maximizing their potential yields.
