Empowering Plants with Science

Ascribe develops natural crop protection products that help farmers reduce disease and increase yield without harming the environment or human health.

Why Choose Ascribe?

Ascribe’s products are based on naturally-occurring small molecules from the soil microbiome. Our biobased products are shelf-stable, durable, and more reliable under diverse field conditions than live microbes or complex mixtures. We offer farmers an alternative to toxic chemistry or expensive biologicals.

Safe for the environment and human health

Real results in the field

Flexible to fit modern operations

Our Technology

The core of Ascribe’s technology is a proprietary discovery platform that applies tools of metabolomics to the soil microbiome to identify the small molecules that mediate beneficial interactions between soil microbes and crops.

Ascribe’s lead product, Phytalix®, acts like a vaccine for plants

Phytalix® is based on a naturally-occurring molecule produced by organisms in the soil. Plants react to Phytalix® by priming their defense pathways. Once primed, crops respond more quickly to pathogens and can ward off infection. Phytalix® has proven effective in controlling a broad spectrum of pathogens in lab and field trials across multiple crops like corn, wheat, soy, rice, potatoes, and tomatoes.


Phytalix® is nontoxic, biodegradable, and non-GMO


Phytalix® treatments are effective at minimum concentrations requiring only milligrams of active ingredient per acre.


Phytalix® can be applied as seed treatment or foliar spray.
