Field treated with Tendovo — Tendovo herbicide 61.7 bu/A avg

+5.3 bu/A yield advantage

Syngenta Grow More™ Experience Site – Rend Lake College, Ina, IL (2023): Tendovo^® (2 qt/A) vs. Zidua^® PRO (6 oz/A).

Field treated with Zidua PRO — Zidua PRO herbicide 56.4 bu/A avg

Start with crop safety, end with more bushels.

Harsher herbicides like Fierce^® MTZ can burn both your beans and your bottom line. In field trials, Tendovo preserved 34,000 more plants or ~$22 per acre than the competition¹, promoting stronger overall stands that close the rows faster.

Faster canopy means even fewer weeds — almost like adding a “fourth mode of action” in the field² — shading out yield-robbing species like Palmer amaranth, waterhemp, kochia, ragweed, marestail and others before they can take hold. With less competition, soybeans build more nodes, set more pods and fill more bins.

In university trials, that early-canopy advantage helped Tendovo protect 4 to 5 more bu/A than competitive herbicide brands.³

We’d call that a win-win-win.

In trials, Tendovo preserved 34K more plants/A vs. Fierce^® MTZ, helping rows close faster and yield higher¹
Faster canopy = fewer weeds = more pods = more potential yield

WEED CONTROL WITHOUT SURPRISES

Some herbicides aren’t labeled for coarse soils—like Kyber^® Pro.

Tendovo is labeled for all soil types and all soybean systems — traited or conventional. Unlike other herbicides, Tendovo offers specific rates for any soil on your farm, so you can move with confidence, not caution.

Labeled for all soils and soybean systems
Specific rates for any soil, including course soils
No stunting. No stand loss. Just clean rows until canopy.

While others stall, Tendovo keeps soybeans surging.

"Do not apply on coarse textured soils with less than 1.5% organic matter."

Kyber^® Pro herbicide

Some preemergence herbicides come with limitations. Others aren’t even labeled for use on every soil. But not Tendovo.

Pre with Tendovo. Post With No Regrets.

Start your soybean surge with Tendovo, and you won’t just get ahead of weeds like waterhemp — you’ll be ahead of the yield curve.

No crop stress. No canopy delay. No compromise to nodes, pods or yield ceiling. Talk about having it all.

And no matter what genetics you plant — Enlist E3^® soybean trait, XtendFlex^® soybean trait, LibertyLink^®, Roundup Ready^®, Roundup Ready 2 Xtend^®, conventional — Tendovo helps protect your potential yield.

Following Tendovo with Dual Magnum^® post-emergence herbicide helps extend protection and boost potential yield — especially when late-season weeds threaten.

Adding Dual Magnum in the tank helps add +3 bu/A
At $10 soybeans, that's $30 more per acre³
Overlapping residuals protect yield through harvest

Clean Start. Strong Finish.

No post can stand alone, and making your post application into a weedy field could mean losing 1% yield per day.⁴

Adding a solid residual like Dual Magnum^® herbicide can make all the difference for your post pass and your yield results.

1% + 1% + 1% + 1% + 1% + 1% + 1% = 7% Losing 7% yield per week

In this trial, both programs started with Tendovo, but only one added Dual II Magnum to the post — and that one walked away with +3 bu/A. At $10 soybeans, that’s $30 more per acre⁵, just by covering the gap between pre and canopy.

Overlapping residuals stop late-season pressure, help soybeans close the row faster and protect the yield you planned for — right through to harvest.

Healthy plants Don’t Stall. They Surge.

No stress means more nodes, more pods and more yield.

Pair Tendovo with Saltro^® fungicide seed treatment and MagniSafe^® technology for even faster canopy, stronger plant health and no stress — from day one.

Saltro protects below. Tendovo defends above. Together, they give soybeans a clear path to higher yield, free from early-season threats and late-season stall-outs.

What Growers Are Saying About Tendovo

No-Stress Success Stories

“I love the crop safety and long-lasting residual. We’ve been wet and couldn’t make a post application, but Tendovo is still holding strong.”
Joey G., Grower, Austin, MN

“I used to rely on BroadAxe^®, but after talking with my Syngenta rep, I switched to Tendovo. It has given me that window of opportunity to come back and not have large-seeded broadleafs like giant ragweed. And when I pair it with Saltro, I get clean emergence without the burn I used to see with ILEVO^®. It's just both of those together make for more yield at the end of the day.”
Lance M., Retailer, IL

“Tendovo is a much-needed product for us. It provided excellent weed control performance and didn’t damage the soybeans.”
Lonnie Egdorf, Retailer, George, IA

“We tried planting some March 20 soybeans. It was more or less an experiment. I used Tendovo as my base pre emerge and we post sprayed in early June. My beans are clean, and I'm very happy with my results.”
Mark G., Grower, Shattuc, IL

“Tendovo gave us the best weed control in years. Our 200 acres were clean the entire year. These soybeans had a 4.5 bu/a yield advantage over the local average.”
Andrew Thilges, Retailer, Owatonna, MN

FAQ

Tendovo provides residual control of 70+ tough weeds, including Palmer amaranth, waterhemp, kochia, ragweed, and marestail. With three effective modes of action, it delivers broad-spectrum coverage to help soybeans stay clean through canopy closure.

See full weed list on the Tendovo product label.

Yes. Tendovo^® is labeled for all soil types, including coarse soils, with specific use rates listed on the label for each soil type. This flexibility means you can apply Tendovo with confidence across every acre on your farm. View label details.

Tendovo^® can be used across all trait platforms — Enlist^® E3, XtendFlex^® soybean trait, LibertyLink^®, Roundup Ready^®, Roundup Ready 2 Xtend^®, and conventional soybeans — with no restrictions. This compatibility makes it a reliable fit for any soybean system.

Tendovo^® delivers long-lasting residual control, up to five weeks⁶, depending on soil type, weather, and weed pressure. This extended window reduces weed escapes, keeps fields cleaner longer, and protects soybeans until canopy closure, giving plants the best chance to reach full yield potential.

Tendovo^® helped deliver faster canopy closure, stronger stands, and higher yield protection⁷ than products like Zidua^® PRO, Kyber^® Pro, and Fierce^® XLT with higher yield potential and fewer crop injuries. On average, Tendovo helped protect 4–5 bu/A more yield⁸, delivering a stronger return on investment with fewer crop injuries.
