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.

Over the past handful of months, I’ve attended a whole pile of potato seminars, expos, forums and conferences around the world. Regenerative agriculture and sustainability are almost always top of the agenda.
I convinced the director of agronomy for a large company that grows chipping potatoes to try soil fumigation with chloropicrin (sold as Strike). He appreciated the soil health and yield gains he achieved in year one, but he hasn’t been seeing the longer-term soil health gains.
We conducted a two-year trial comparing potatoes grown in soil where disease was managed with Strike (chloropicrin). Based on what we observed in the field regarding tuber set increase, we developed a model that incorporated the benefit of set increase from Strike in a seed production system.
Chad Hutchinson is pleased to discuss soil microbes and sustainability with Joy Youwakim, an agroecology scientist at Biome Makers, an independent, third-party genomics company that specializes in DNA sequencing of agricultural soil samples.
Potato wart strikes fear in the bravest among us and at every level of the potato value chain. 36 fields have been identified as infected in three counties since 2000, leading to major trade disruptions, the destruction of hundreds of millions of kilograms of potatoes.
In the Summer/Fall of 2022 TriEst Ag Group did a mixture study that focused on Enterolobii in Nash County, NC. The trial evaluated the use of TELONETM, C15, and C35 at 6 GPA (22 GPA broadcast) shank applied in-row 14” deep with 10” of stack.
There is a lot of talk about sustainability and regeneration in agriculture these days. But what do those terms really mean? If you ask five people, you might get five different definitions. But for Josh Mays, Director of Agronomy for TriEst Ag Group, it all starts with profitability.
A group of scientists at the University of Florida have been investigating the impact of soil fumigation on microbial communities and recently published some of their findings. They found that fumigant treatments with greater than 60% chloropicrin consistently increased tomato yield
Watermelons are a popular crop in Japan. Unfortunately, they are also highly susceptible to destructive root-knot nematodes which negatively impact overall yields and fruit quality. Japanese growers know that nothing is more effective against nematodes than TELONE™!
68% of all seed potatoes sold in the Pacific Northwest are infected with verticillium. If you are a potato farmer who doesn't currently battle verticillium and you’re buying seed potatoes, you have a more than two in three chance that you’ll bring verticillium in.
Chloropicrin has been used as an agricultural product for soil-borne pest suppression in specialty crops throughout the world for over 60 years. It is a bio-nutritional soil fumigant that breaks down into elements that are naturally utilized by plants: carbon, chlorine, nitrogen, and oxygen.
Farmers are hungry for tangible ways to increase their sustainable efforts while maintaining economically viable yields. A lot of voices are calling for farming reform. However, feel good soundbites don’t feed the world. Potato producers are keen for real solutions.
Strike soil fumigants provide a barrier of protection from soil borne disease in the first 6 to 8 weeks, buying time for the onions to yield a healthy and vigorous root. Soil health studies prove that Strike suppresses disease while also supporting biological diversity and soil health overall.
The farmers are dealing with verticillium. The table of farmers started by laying out the stark reality: “Verticillium is trouncing our crops.” The agronomists and plant pathologists present spent the discussion recommending: “Try cover crops”, “Try manure”, “Try compost”.
Plant-parasitic nematodes are some of the most destructive pests in agriculture. With over 4,000 species of plant-parasitic nematodes worldwide, identifying and managing the right ones in your fields is crucial.
Chloropicrin has been a trusted soil fumigation solution for over 60 years, helping specialty crop growers around the world maximize yields and maintain healthy soils. But what makes it such a powerful tool? Here’s a closer look at some of its benefits:
The Pacific Northwest is known for producing hops that can be devastated by pathogens such as Rhizoctonia solani, Verticillium, Fusarium, and Alternaria. These pathogens can result in stunted growth, wilting and root decay which drastically impact plant growth and consequently hop yield and quality.
Soil fumigation is a pre-planting practice that works by penetrating throughout the soil profile to address threats like nematodes, fungi, bacteria, and insects, creating a pathogen-free root zone, soil fumigation lays the foundation for a healthier growing environment.
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.
Trical Group's John Washington released a paper on fumigation using Chloropicrin and 1,3-dichloropropene (1,3-D) and its impact on microbiological communities and soil health.
No current practice in potato production provides more benefits than soil fumigation. Soil fumigation with Strike allows plant roots to develop in an environment where nematodes and other soil borne diseases are managed.
This past Fall we established 2 multi-year field trials in California. Our main objective is to examine the benefits of TELONE™ and Chloropicrin providing early rootstock establishment, promoting early growth, and stronger root systems as we have documented in other crop markets.
TriEst wanted to look at finding application and timing solutions to better meet nematode and disease pressures. The 2023 trial focused on sampling depths to map location of pests, dual depth applications to place the correct product in the right place, and proof out these concepts.
Nematodes are a common pest in potato-growing areas, particularly in the Pacific Northwest. This blog post will cover common nematodes affecting potatoes in the Pacific Northwest, and recap a potato field trial that was done to demonstrate TELONE™ efficacy.
In 2023, Trident Agricultural Products conducted field trials in Idaho, focusing on kidney beans for seed production. The trials aimed to evaluate the effectiveness of PIC 100 (Chloropicrin) at low dosage rates of 2.5 GPA and 5 GPA at maximizing yield and income gain in comparison to non-fumigated checks.
