USA - New corn herbicide from Syngenta hopes to improve pigweed, giant ragweed control

Syngenta, a seed and agrichemical producer, will launch a new herbicide in 2024 that will give growers three weeks longer residual weed control than other corn herbicides.

Upon approval by the Environmental Protection Agency, Syngenta’s Storen will use four active ingredients to provide more consistency and length to provide maximum weed control.

″It will be a wide application window,″ Syngenta agronomist TJ Binns told Michigan Farm News during the Commodity Classic in March. ″We will be able to go 28 days pre plant all the way up to V8 corn.″

Storen combines four residual active ingredients — BIR, mesotrione, S-metolachlor, and pyroxasulfone — plus the crop safener benoxacor in one premix. The combination of these four active ingredients work together to provide weed control of barnyardgrass, foxtail species, waterhemp, Palmer amaranth, giant ragweed, common ragweed, Russian thistle, Cocklebur and Morningglory species.

The company also said Storen will control broadleaf weed-resistant biotypes tolerant to acetolactate synthase, triazine and glyphosate herbicides.

″I am from western Kansas, and resistance is one of those things we’ve always dealt with, and it’s continued to evolve,″ Binns said.

″We’ve had to evolve our management techniques around that. The last two to three years I’ve talk to more growers, crop consultants who think we need to control these things before they come out of the ground.″
