If your growers’ corn is stressed out after a glyphosate treatment, make sure they contact Syngenta Seeds. Which five hybrids are the cause for concern?
Syngenta Seeds is contacting corn growers and seed dealers who purchased five hybrids grown in a narrow band of the northern U.S. Corn Belt. While not all plantings of these hybrids have exhibited symptoms, some have shown stress following glyphosate treatment. The five hybrids share a single parental line, range from 100 to 103 days of maturity. They are:
- Golden Harvest H-7542GT
- Garst 87Y26GT
- NK N48G-GT
- NK N48R-GT
- NK N48R-GT/CB/LL
Growers who have planted these hybrids are urged to contact Syngenta at 800-258-0498 before making any further crop management decisions, including application of glyphosate. “These hybrids represent less than one percent of our corn seed portfolio and less than one-tenth of one percent of total U.S. corn acres,” says Chuck Lee, Corn Product Line head, Syngenta Seeds. “We are working with growers who have purchased these hybrids to assess options to avoid or mitigate any potential damage from these stress symptoms.”
The seed passed all quality control tests and the glyphosate tolerant trait is expressed. “We currently attribute what we are seeing primarily to environmental conditions affecting one specific parent line common to these hybrids,” says Lee. “All other hybrids are performing as expected. As always, we stand behind our products and we are reaching out proactively to growers who have purchased these products.”
