With EPA approval in hand, PI AgSciences introduces PHC68949, peptide-based novel approach to control plant-parasitic nematodes. Designed with short chains of amino acids, it’s technically a biological crop protection product, but its scientists say it provides next-level nematode suppression.

“It is a defense activator that helps the plant defend against plant-parasitic nematodes. Where a nematicide has activity on the nematode, this product gets the plant ready to defend itself and activates the pathways in the plant–thickening cell walls and roots,” says Wes Hays, North America commercial lead at PI AgSciences.

A biological that handles like a synthetic

Hays says this is an extra tool in the farmer’s toolbox with its new mode of action.

“It’s totally different than most products farmers use today. And its performance is extremely compelling. It’s very similar to most synthetic chemistries in the market for nematodes today–providing the consistency, shelf life and compatibility of a synthetic, but it’s a natural product.”

Approved for use on row crops and specialty crops, Hays says the use rate is low—1 to 2 ounces per acre, subject to state registrations and final product labels.

“There’s flexibility with application—in row crops, you can use it as a seed treatment or a foliar. For example, you can put this into your first post herbicide pass. And for specialties, it’s almost predominantly a foliar application, which opens up flexibility beyond drip irrigation or drench applications.”

Where and when to find this new product

With EPA approval, PI AgSciences is now working on state level label requirements. Limited quantities of the product will be available for 2026, with full commercial launch coming in 2027.

This is the company’s third active ingredient for the agricultural market. For commercialization of its products, PI AgScience partners with distributors in the industry including Wilbur Ellis, Helena and Brandt.

PI AgSciences is the agricultural division of India-based PI Industries, a global life sciences company that custom manufactures active ingredients and intermediates. And the recent product introductions are one result since the August 2024 acquisition of Plant Health Care, headquartered in St. Louis, Missouri.
