Research and Field Reports
Effective weed control in pastures and hayfields requires targeted solutions that minimize herbicide waste and protect forage grasses. The research studies featured in this section evaluate the GrassWorks Weed Wiper™ in university trials and real-world applications, demonstrating how precision herbicide application improves weed suppression without damaging desirable crops.
These studies, conducted by universities and livestock producers, explore the effectiveness of weed wipers compared to traditional spraying methods. Each report provides data-driven results to help farmers, ranchers, and land managers make informed decisions about weed control strategies.
Explore the research below to see how GrassWorks Weed Wipers have been tested and proven in scientific trials and real-world operations.
University Research on Smutgrass Control
Mississippi State University Study
Study Focus
Smutgrass (Sporobolus indicus L.) is an aggressive, invasive weed that reduces forage quality in pastures and hayfields. Researchers at Mississippi State University evaluated the effectiveness of weed wipers for smutgrass control, testing Velpar® (hexazinone) and glyphosate using the GrassWorks Weed Wiper™.
Key Findings
Velpar® achieved 95% control, but it was costly and affected desirable forage.
Glyphosate at 50% concentration in a double pass reached 90% control, offering a cost-effective alternative.
Single-pass applications were less effective, reinforcing the importance of thorough herbicide contact.
Why It Matters
This study shows that weed wipers provide precise herbicide application, reducing chemical drift and improving smutgrass suppression without harming surrounding forage.
Managing Weeds in Pastures & Hayfields
West Virginia University Study
Study Focus
Researchers at West Virginia University, led by Dr. Rakesh S. Chandran, tested the effectiveness of weed wipers for ironweed suppression in pastures. This study compared traditional weed wipers with the GrassWorks Pull-Type Weed Wiper™, referred to as a rotary weed wiper in the report.
Key Findings
Grazon P+D provided 93% weed suppression, proving to be the most effective herbicide.
The GrassWorks Pull-Type Weed Wiper delivered better herbicide contact and weed suppression than traditional wipers.
Clover populations remained stable, showing that targeted herbicide application helps preserve desirable plants.
Why It Matters
This study demonstrates that weed wipers improve pasture management, allowing for selective herbicide application that reduces chemical waste and protects forage grasses.
Effective Weed Control for Beef Producers
Field Report from U.S. Cattle Producers
Study Focus
Cattle producers across the U.S. have adopted weed wipers to control smutgrass, johnsongrass, and broadleaf weeds while reducing herbicide costs. This report highlights real-world experiences from beef producers who have used weed wipers to improve forage quality and pasture productivity.
Key Findings
California trials showed effective control of mint, chicory, and smutgrass, improving pasture quality.
Texas ranchers reduced smutgrass infestations across 100+ acres using a GrassWorks Weed Wiper.
Kentucky hay producers cut herbicide costs significantly, treating 30 acres with less than 2 quarts of herbicide.
Why It Matters
This field report provides firsthand accounts of cattle producers successfully managing weed pressure, confirming that weed wipers are an efficient, cost-effective solution for pasture and hayfield management.
