Tendovo soybean herbicide from Syngenta earns rave reviews during first season of use

Released in 2022, Tendovo is setting a new preemergence standard 

Tendovo® soybean herbicide has been shown to provide superior weed control while reducing crop stress for higher potential yield.

GREENSBORO, N.C., USA, March 8, 2023 — Syngenta reports that initial retailer and grower experiences with Tendovo® herbicide have been extremely positive and illustrate how the product is redefining weed management in soybeans. 

Weed Control  

Eric Palmer, technical product lead at Syngenta, explains Tendovo soybean herbicide was available in limited quantity for the 2022 growing season. Retailers and growers using the herbicide were invited to join the Tendovo First Look Program.   

“As the season unfolded, we were able to follow along with these first-year growers and retailers as they shared their experience using the product,” Palmer said. “From the Gulf of Mexico to the North Central U.S.—across approximately 200,000 acres—Tendovo demonstrated how it offers preemergence weed control without compromise.”  

Growers and retailers who participated in the Tendovo First Look Program were invited to submit performance photos of their fields from emergence through harvest as well as feedback on the product.  

“Tendovo is a much-needed product for us. It provided excellent weed control performance and didn’t damage the soybeans,” said Lonnie Egdorf, retailer from George, Iowa. “We will use it again next season to give us multiple modes of action and take weed control to the next level in the early season.” 

Crop Safety  

Palmer noted that crop safety and weed control should be a high priority for growers as they plan for the 2023 season. Any damage to the crop may lead to yield loss, so it is important to ensure the crop remains healthy from planting to harvest. This means it should be a high priority to get a healthy stand while eliminating early season weed competition.  

“Growers should consider a preemergence herbicide that provides excellent residual activity without the risk of crop injury or stand loss,” Palmer said. “Fields treated with Tendovo achieved earlier canopy, better plant stands, healthier root mass and optimal plant populations.”1 

Yield Potential 

“Because Tendovo controls early germinating weeds and provides excellent residual, it protects the crop from yield-robbing weeds results in superior yield potential and ROI potential” Palmer said. “Tendovo gave us the best weed control in years,” said Owatonna, MN retailer Andrew Thilges. “Our 200 acres were clean the entire year. These soybeans had a 4.5 bu/a yield advantage over the local average.” 

“Tendovo performed for growers just like it did in our development trials. The combination of outstanding weed control and crop safety resulted in 4-5 bu/A greater yield when compared to competitive herbicides.2 We’re excited that more growers will have an opportunity to experience the benefits of Tendovo this season.”
