Difficulty controlling grassy weeds in drought-stressed St. Augustine grass without causing turf injury.

Workarounds Described

• using reduced-rate spot treatments to minimize injury
• relying on cultural practices like hand-pulling
• waiting until turf is less stressed before applying

Implied Software Gaps

• A decision-support tool that factors in real-time turf stress to guide herbicide application timing and rate
• A dynamic risk assessment model that predicts injury probability for specific weed-turf-chemical combinations under current conditions

TurfSafe Weed Control

A precision herbicide guidance app that uses real-time weather and turf stress data to recommend the safest application timing and rate for post-emergent grassy weed control in sensitive warm-season grasses like St. Augustine.
