New Dyna-Gro Varieties Four Years in the Making

New Dyna-Gro Varieties Four Years in the Making

Dyna-Gro is ready to go.

Part of Nutrien Ag Solutions (formerly known as CPS), Dyna-Gro continued to enjoy success in 2018, with its proven DG 3385 B2XF still among the top ten varieties planted this year, according to USDA. But it’s what’s ahead for 2019 that Shawn Carter excited.


“I think 2019 is going to be a big year for us,” says Carter, Dyna-Gro Seed Manager for the Southwest. “All of the material we’ve been working on for the past four years on trait integression is finally here. We have production acres in the field, and we’ll have supply to sell. We wanted to make sure we had the right products, since we have to sell our customers fertilizer, chemicals and seed and see them all year long.

“We’re going to launch seven new varieties in 2019,” he adds. “All are B3XF varieties, and they address and correct issues in our lineup. Diseases have been a big problem in west Texas for the last 4-5 years with bacterial blight, Verticillium wilt, and fusarium. Selecting for the right disease package in our breeding program has been a big issue for us.”

Of the seven planned varieties, six are rated above average-to-excellent for disease management. Each variety will include bacterial blight resistance and a highly-rated Verticillium wilt tolerance. One variety has shown complete resistance to the Race 4 fusarium that’s impacting California and parts of south Texas.

The new lineup is the result of the company’s aggressive plant breeding program, headed by Dr. Charlie Cook, who handles varieties for Texas and manages the overall program. A second breeder – Bob McGowen – was added this year in Mississippi.

Details about some of the new varieties are still being finalized, but here’s a look at some of what growers can see from Dyna-Gro in 2019:

DG 3402 B3XF. Early-to-medium maturity adaptable for Texas and the Southeast with excellent fiber quality and seedling vigor, bacterial blight resistance and excellent storm tolerance.

DG 3421 B3XF. Early-to-medium maturity also adaptable for Texas and the Southeast with excellent fiber quality, storm tolerance, and above average Verticillium wilt tolerance.

DG 3530 B3XF. Medium maturity in a modified bushy plant type with semi-smooth leaves. It is widely adaptable from the Southwest to the Mid-South, Southeast and East Coast, and is very responsive to irrigation and intense management.

DG 3570 B3XF. Medium maturity with a fit across the southern Cotton Belt with above average quality and strong seedling vigor. It is recommended for both dryland and irrigated fields.

DG 3555 B3XF. Medium maturity adapted for the Mid-South and Texas, with excellent fiber quality and seedling vigor, excellent Verticillium wilt tolerance and bacterial blight resistance, and strong storm tolerance.

DG 3615 B3XF. Medium-to full maturity adapted for Texas, the Mid-South and Southeast, with excellent fiber quality and seedling vigor, plus excellent Verticillium wilt tolerance, bacterial blight resistance and storm tolerance.

“We’re excited about this new lineup,” says Carter. “Quality, seedling vigor and seed size are all top notch. All of the issues we’ve had for the last 4-5 years have been addressed with these new varieties.”
