Published in 2025, a study conducted at Texas A&M University analyzed the efficacy of using PV35X drones for crabgrass control. Researchers measured herbicide application performance against standard ground-based backpack sprayers.
Why it matters
This research aimed to determine how nozzle selection and water-carrier volumes affect herbicide efficacy when using aerial technology for turf management. Understanding these variables is critical for optimizing drone-based applications for weed control.
The study utilized a drone with a 25-pound payload and 3-gallon solution capacity operating at 3.6 feet. Ground-based backpack sprayers maintained a walking speed of 3.5 mph, significantly slower than the 6.7 to 10 mph drone flight speed.
The players
Texas A&M University
This public research university and land-grant institution served as the site for the crabgrass herbicide application study.
The details
The study found that aerial sprayers equipped with DG and AI nozzles performed similarly to backpack sprayers, while XR nozzles suffered from drift due to rotor downwash. Backpack applications provided the highest overall spray solution coverage on large crabgrass plants.
Timeline
The findings were published in the Weed Technology journal in 2025.
Deeper Dive
This study aligns with the Weed Technology journal herbicide application standards by testing whether modern autonomous aerial platforms can match historical spray efficacy. It marks a departure from traditional manual methods by proving that drone nozzle selection is essential to mitigating rotor-induced drift.
Homeowners and land managers may soon see faster, drone-based weed control services hitting the market as the technology matures for site-specific use. Adopting these aerial solutions could eventually reduce the manual labor time required for treating large turf areas.
The takeaway
Using drone technology for herbicide application requires careful nozzle selection to prevent spray drift caused by rotor downwash. Proper calibration is essential for achieving the same level of coverage as traditional manual backpack systems.
