After the strong response to August’s Soil Under Siege panel on black dot, Spud Smart and TriCal Group are bringing together three leading soil health experts for a candid discussion on common scab — one of the most stubborn and costly diseases in potatos.
Another year brings another successful potato trial at Trident Ag Products. This season, we expanded to two trials and increased the plot size to half pivot fields. Our multi-year approach allows us to work closely with growers and monitor performance over time, helping us gather strong, reliable data.
Black dot is spreading in potato fields — and farmers are right to be concerned. While not a new disease, black dot is becoming tougher to manage, stealing yield, blemishing tubers, and reducing marketability. That’s why Spud Smart brought together three experts for the Soil Under Siege panel.
One of the most underestimated culprits f crop loss Colletotrichum coccodes, or black dot, this pathogen thrives in stressed plants and plays a key role in the early die complex. But despite its impact, it’s often confused with or overshadowed by more familiar threats like verticillium wilt.
Stronger plants, better yields, fewer resources - and a lower carbon footprint. Potato growers face big sustainability goals, but with the right tools, we can get there—without sacrificing productivity. One tool that’s helping make this possible is Strike, driven by the chloropicrin.
Trident Ag Products and Dr. Maxwell Handiseni are conducting a potato trial in Boardman, Oregon, focused on tackling pathogens like verticillium wilt and black dot in potatoes using chloropicrin, the active ingredient in Strike™ Soil Fumigant.
Black dot has historically been overlooked in potato seed production. Recent research shows that black dot, caused by the fungus Colletotrichum coccodes, working synergistically with Verticillium dahliae and root-lesion nematodes to weaken plants and reduce yields.
Trident Ag. recently completed Strike™ fumigations in potato fields in Washington State to help control soil-borne diseases like Common Scab, Verticillium wilt, and Black Dot, ensuring healthier soil and better crop yields.
When growers apply Strike soil fumigant under their carefully managed field conditions, they get impressive results — control of rhizoctonia, black dot, common scab; boosted crop yield and improved sustainability.
You’ve seen the research study results that show soil fumigation with Strike can effectively subdue rhizoctonia, black dot, common scab, and early die complex. You’ve heard experts explain how chloropicrin can boost soil’s health and potato production’s sustainability.
Dr. Chad Hutchinson reviews how soil fumigation with Chloropicrin helps tackle potato scab, black dot, rhizoctonia, verticillium wilt, and nematodes while positively impacting overall soil health.?
