Why would USA help bail out Argentina while they take American soybean producers’ biggest market??? We shld use leverage at every turn to help hurting farm economy Family farmers shld be top of mind in negotiations by representatives of USA

Bt traits alone aren’t holding up. Resistance is spreading, and farmers across the Corn Belt are seeing the impact of this harvest. Persistent BioControl nematodes add a new mode of action. Not a replacement, but layered protection that extends trait durability, protects yield,

One application. Decades of protection. Persistent Biocontrol Nematodes don’t just survive a season — they establish in your soil and keep working year after year. Visit https://t.co/uUaJpHAOQn to learn more. #BuiltToPersist #HealthyRoots #SoilSolutions #RootwormControl

Next year’s rootworm problem is starting now. Each female rootworm beetle lays ~300 eggs in late summer. Those eggs will hatch next spring into larvae that feed on your roots — unless something is waiting for them. Applied in the fall, persistent biocontrol nematodes establish

First year in this field for SmartStak Pro and economic rootworm damage. Field has a history of trait failure. Biocontrol Nematodes applied the previous growing season prevented rootworm injury on the half of the field inoculated.
Looking for interesting topics for your fall/winter meetings? We'd love to come talk about biocontrol nematodes for corn rootworm control!

The soybean tentiform leafminer (Macrosaccus morrisella), a new pest of soybeans, has been found in Missouri. First detected feeding on soybeans in MN in 2021, this pest has also been confirmed in NE. @MizzouIPM

You can’t see it happening — but it’s happening fast. After application, our nematodes go to work: Hunting soil insect larvae like corn rootworm Entering through spiracles openings (breathing holes) Releasing symbiotic bacteria that kill the pest in 24–48 hours Reproducing and

You’re already using traits. Maybe insecticide, too. But if you're still finding rootworm damage, it might be time to add one more layer. Persistent BioControl nematodes give you an additional below ground mode of action — right where rootworm resistance starts. One application,

Your corn roots have a story to tell. Now’s the time to dig. Look for root scarring, pruning, or signs of early lodging — especially if you had rootworm pressure last year. Understanding last year’s pressure is the first step to protecting next year’s crop. Learn what to look

Looks like extended diapause rootworm problems could be more prevalent in MN corn this year.
