The Weed Seed Bank is the only bank where a zero balance is encouraged. We don’t have much control over weed seed withdrawals but do have ways to reduce deposits made by increasing control of resistant weeds. Adding Pyridate, a unique and underutilized mode of action can help achieve that goal.

Early in 2000, HPPD herbicides grew popular when ALS Inhibitors started showing resistance. Fast forward to the 2020s, the weed spectrum changed and more weed species are becoming resistant to different Groups of Chemistries. Could an “old” chemistry, and different MOA bring “new” life to the mix?

“I have kind of a saying and that is to kill every weed at least twice. The idea there is if you’re just killing the weed once, or if you’re just using one effective herbicide mode of action on that weed, eventually you’re going to have a weed that’s going to be resistant to that one.“ Dr. Tranel Univ. of IL

If a postemergence program provides 95% control, and 50 common waterhemp plants per acre, are left behind, quality and yield can be impacted. With up to 400,000 seeds per plant, that could mean 20 million seeds per acre! Adding Pyridate, a unique and new mode of action can help achieve 100% control.

Palmer amaranth and waterhemp are intense competitors requiring growers to rewrite the weed control playbook. Chemistries that dominated the field years ago, are now losing the fight. Belchim USA brings a veteran player, Pyridate providing a different MOA, to your integrated weed management team.

Experts agree that a “team,” with alternate Mode of Actions, is essential to beat resistant weeds. A post emergence program providing 95% control still allows 5% of weeds to escape. Adding a new MOA can improve your chances of complete control of weeds such as Palmer Amaranth and Common Waterhemp.

Herbicide resistant weeds have been a fierce competitor of crop producers for years; and the challenge continues. Experts realize, there is no “silver bullet” to control resistant weeds and suggest that growers use multiple “players” (alternate MOA’s) to increase the chances of winning the “game”.

Adding TOUGH® 5EC (Pyridate), a Group 6 fast acting, foliar herbicide, to the tank mix enhances the speed of kill of resistant weeds. Why is a faster speed of kill important? Research shows that 80% of Mesotrione can be metabolized in just 24 hours; 80% of Atrazine in half that time.

These weeds can produce 100,000 to 400,000 seeds when competing with a crop. Seeds are small and are easily dispersed. A post emergence product providing 95% control still allows 5% (50 plants per acre) to escape. Based on this, the potential for escape is 50 X 400,000 = 20 mil seeds/acre!

TOUGH® 5EC PHOTOSYNTHESIS II INHIBITOR Pyridate works by blocking a weed’s photosystem II process, triggering the release of toxic forms of oxygen, causing rapid cell wall degradation. Pyridate is a highly effective MOA in corn showing increased levels of weed control in tank-mix combinations.
