Beyond glyphosate: Quercus Bio targets weeds with designer proteins
Source: AgFunderNews
As resistance to legacy chemical herbicides spreads and biologicals struggle to scale, a new class of crop protection tools is emerging that aims to combine the best of both worlds. Quercus Biosolutions is designing “mini proteins” from scratch—leveraging AI tools first developed in drug discovery—to target sites of action inside plants and unlock new modes of action in weed control.
If the approach delivers, such designer proteins could account for half of the crop protection market within the next 10-15 years, predicts cofounder Jonathan Lightner, PhD. AgFunderNews ( AFN ) caught up with Lightner (JL) at World Agri-Tech in San Francisco to discuss how advances in protein structure prediction and AI-driven design are now making their way into agriculture.
AFN : What’s attractive about mini proteins in crop protection? I see proteins in general and small designed proteins specifically, really sitting in a great space between chemical crop protection and biologicals.
Why this matters: For operators, the real question is whether the sensing, control, or data layer creates faster and better decisions. The facilities that win are the ones that turn visibility into tighter control and tighter control into better outcomes.
Frequently Asked Questions
How is AI being used in agriculture operations today?
AI is increasingly being used to analyze production, supply chain, and monitoring data faster than manual review. The practical value comes when those insights lead to better decisions on operations, forecasting, and resource allocation.
What makes an AI tool useful for operators instead of just interesting?
A useful AI tool helps operators detect patterns earlier, reduce labor-intensive analysis, and connect data to actions that improve margin, consistency, or throughput.
