    Pulse Width Modulation Technology for Agricultural Sprayers

    This publication provides information on pulse width modulation (PWM) technology including its working principle, components, benefits, and best management practices for its optimal utilization on agricultural sprayers. Pulse width modulation technology was developed to overcome pressure variation issues, as the flow rate is varied by changing the cycle of the electronically actuated solenoid valves while the system pressure remains constant throughout the boom.

    Keep Wild Radish Out of Fields You Plan to Seed Into Greens!

    This report provides research and extension results for trials conducted by the University of Georgia Vegetable Team and its collaborators in the 2024-2025 growing season. The goal of this project was to find potential ways to manage wild radish in seeded greens such as mustard, turnips, collards, and others. Wild radish, a member of the mustard family, has historically been recognized as a winter annual weed mainly infesting winter crops grown across the Southeast. Contributing authors include county and regional faculty as well as specialists from UGA’s horticulture, plant pathology, crop and soil sciences, and entomology departments. All research has been supported by the Georgia Commodity Commission for Vegetables.

    Smutgrass Control in Pastures and Hayfields

    Producers growing grasses for hay or forage can use this resource to learn about, identify, and control smutgrass. Perennial grass weeds can be problematic in forage systems as few herbicides are available, especially for use in bahiagrass and tall fescue. An integrated weed management plan is critical for combatting smutgrass in Georgia forage systems. For example, a timely fertilizer application following hexazinone can accelerate bahiagrass recovery giving it a competitive advantage over other weed species. This resource also includes a brief summary of smutgrass research at UGA.
