Field Crops, Forage and Turfgrass Production Resources

RevisedSome of the most widely adopted precision agriculture technologies include guidance systems that utilize a Global Positioning System (GPS). Although these technologies are most commonly utilized in row-crop agricultural systems, they also have many potential benefits in forage-based production systems. With so many different options to choose from, it can be a daunting task to determine which technologies are the best fit for a specific farming application and budget. When coupled with a differential GPS system (which are available in various levels of correction accuracy), the accuracy of these guidance systems can be greatly improved. The main goal of this bulletin is to cover the currently available GPS guidance options for forage production systems.

RevisedBoom sprayer calibration using conventional methods (catching flow for certain time or distance) for large (60-90 ft; 54-72 nozzles) boom sprayers can be a time-consuming process. This short publication outlines steps to take to verify nozzle output and calibrate a boom sprayer, including tables with useful information on flow rates at multiple speeds for two common nozzle spacings and an equation for calculating rates if needed.

The lack of proper planter setup and maintenance results in common planting mistakes that affects crop stand and yield every year. Growers can easily avoid these mistakes by following a few simple steps at the beginning of the planting season to ensure proper planter setup for maximized field performance. This simple and easy-to-follow checklist provides tips on how to properly set up different planter components to achieve a high and uniform stand establishment across the field. The checklist also includes a visual to identify the components available on a typical row-crop planter.

In the state of Georgia, gray leaf spot primarily affects St. Augustinegrass and is particularly chronic and damaging in the coastal area of the state. This publication contains important information on the biology of the causal agent, detailed descriptions and photos of the disease symptoms, information on conditions favoring the disease, as well as cultural, genetic, and chemical methods of control. The publication is intended for turfgrass professionals, consultants, county faculty, homeowners, and the general public.

The southern chinch bug is a serious insect pest of turfgrass, especially St. Augustinegrass, in Georgia. Bermudagrass, centipedegrass, and zoysiagrass are also attacked by southern chinch bug. Affected turfgrass can form yellow to brown patches that are sometimes mistaken as indicators of disease or drought stress. Populations of southern chinch bug can build up at the edges of these patches at over 100 individuals per square foot, which can kill the affected grass. The development of southern chinch bug in the grass can easily go unnoticed because of their small size and dark-gray color, which blends in with thatch. This resource summarizes the biology, lifecycle and management options available for southern chinch bug in Georgia.
