A crop protection manufacturer is letting U.S. farmers know of a new product is has in development.

Syngenta announced on March 9 it’s working on a new corn herbicide which will be branded as Storen.

Storen “The new pre- and post-emergence grass and broadleaf corn herbicide will give growers up to 3 weeks longer residual weed control than other leading corn herbicides,” Syngenta said in a statement.

Storen will contain four active ingredients – bicyclopyrone (Group 27), mesotrione (Group 27), S-metolachlor (Group 15), and pyroxasulfone (Group 15). It will also include the safener benoxacor all in one premix.

This product will provide protection against multiple weeds including barnyardgrass, foxtail species, waterhemp, Palmer amaranth, giant ragweed, common ragweed, Russian thistle, Cocklebur and Morningglory species.

Storen will add to Syngenta’s line of products containing bicyclopyrone.

Other products with this active ingredient include Acuron, Acuron Flexi and Acuron GT corn herbicides.

Ask Canada’s most decorated soybean breeder his favourite part of the job and he doesn’t name a single variety. He names the students.

Istvan Rajcan is a professor of soybean breeding and genetics in the Department of Plant Agriculture at the University of Guelph, where he has run the soybean breeding program for 28 and a half years. In that time he has developed 87 soybean cultivars, published 140 refereed papers and trained 51 graduate students. In 2025 he received the Public Sector Impact Award from the National Association for Plant Breeding.

He is also worried. In this episode he says Canada is at a crossroads, pointing to recent government cuts to plant breeding programs and to the facilities that support them. His prescription is structural. "Plant breeding funding formula has to be a long-term one," he says.

The formula he is defending is the public-private matching arrangement his program runs on. Private seed companies fund the work, provincial or federal money matches it, and the combined pool stretches each dollar further than either source could alone. At the National Association for Plant Breeding annual meeting in June, he says American public breeders were often surprised at how well that collaboration works in Canada.

He also describes how the people entering plant breeding have changed. His early graduate students came mostly from farms. More recently they include, in his words, "city kids who just became excited about genetics."
