Our technology was discovered in the Shields Lab at Cornell University and is the result of 35 years of research, 12 papers, and 500,000 soil samples!
‍
The result is revolutionary - persistent entomopathogenic nematodes that are economically viable and highly effective in row crops like corn, wheat, and hops.
