Syngenta is enhancing a corn rootworm insecticide, by putting additional focus on  flowability, handling, and efficacy.

Dean Grossnickle, agronomic service representative for Syngenta, talks in-depth about the qualities of a corn insecticide, introduced in 2018.

“Force® Evo is our new, liquid version of Force®,” Grossnickle said. “It comes as a “bag in box” concept. You can do 40 acres with each box. It holds 2.5 gallons, (with a) use rate of 8 ounces per acre. It offers superior flowability. It can cover a large amount of acres for a grower, and (they) don’t have to handle a lot of product.”

Grossnickle previews a new, high-load granular corn insecticide, Force® 6.5G. Force® 6.5G will provide control against corn rootworm and will be available for use during the 2019 growing season.

“The Force® 6.5G is a new, high-load granular,” Grossnickle said. “You handle half as much product, compared to the 3G version, so farmers can cover twice as many acres and not have to fill the planter as much. Of course, not everybody likes to lug bags and boxes around. It’s a great new step forward.”     

Grossnickle reminds farmers, “If you’re going to grow corn-on-corn, you need some sort of rootworm protection.” Protection options include: seed traits and/or soil-applied insecticides.

Grossnickle talks about the benefits a soil-applied insecticide can provide to an operation.

“In a corn-on-corn scenario, corn rootworm are definitely a problem,” Grossnickle said. “They’re not a problem every year, but they come in pockets and overwinter. (Crops) need some sort of protection, and the soil-applied insecticide does give some protection. If they don’t have any protection, they can have yield impacts as much as 50-70 bushels to the acre because the rootworm devastates the plant root. When they have protection, they can get that maximum yield and have the ROI to help pay the bills.”
