The two-lined spittlebug is an important insect pest of turfgrass in Georgia. It attacks all turfgrass species, but centipedegrass is the most susceptible to spittlebug infestation. It also attacks some ornamental plants, including asters, hollies, and morning glories. The two-lined spittlebug injects toxins into the turfgrass, and the affected grass blades turn yellow and then brown or purple. The damage symptoms start with the development of discolored leaves followed by the complete wilting of the stem and leaves, ultimately causing the death of the grass. There is limited information available to the general public on determining this pest problem and how to manage it, especially during wet years. This publication provides management options and other information on the two-lined spittlebug, including identification and biology, host plants, damage symptoms, and control strategies.

This bulletin provides information for producers, nutritionists, and feed industry personnel on formulating diets to maintain or improve milk composition. The value of milk components is increasing more than skim milk, so this topic impacts all dairy farmers. The publication provides information on feeding dairy cows for improved yield of milk components, providing background on how the cow synthesizes milk components and the dietary factors that affect milk component yield.

Manejo del Viñedo
Este póster del manejo del viñedo está basado en la fenología de la planta y proporciona una referencia para las buenas prácticas de manejo de las enfermedades y los insectos de la vid en un formato atractivo y digerible. Las prácticas vitícolas optimizan la salud, la rentabilidad y la sostenibilidad de los viñedos al mismo tiempo que mejoran la cantidad y calidad del cultivo. Al igual que el manejo de plagas, las prácticas vitivinícolas deben implementarse de manera oportuna a lo largo de la temporada de crecimiento de la planta para maximizar la eficiencia de la práctica y la ganancia de beneficios. El control de enfermedades en las uvas es crítico, ya que las uvas son susceptibles a una amplia gama de patógenos. La implementación de prácticas culturales oportunas y adecuadas ayudará enormemente a eliminar las enfermedades. Además, las uvas, más que muchos productos hortícolas, requieren programas de fungicidas agresivos durante todo el año para mantener la salud de la vid. El manejo integrado de plagas en el viñedo combina una variedad de técnicas y herramientas para controlar las plagas. Comienza identificando correctamente al insecto y comprendiendo su tiempo y actividad dentro de un cultivo a lo largo de la temporada. El monitoreo y la evaluación de la abundancia de plagas identificadas y las lesiones en los cultivos pueden ayudar a determinar el método correcto para el manejo efectivo de la plaga.

Antibiotic therapy continues to play an important role in the control of mastitis in dairy cows. Lactational therapy is effective against Streptococcus agalactiae but less successful against infections caused by Staphylococcus aureus and other causes of mastitis. As a result, alternative treatment strategies have been developed, including a combination of both intramammary infusion and the parenteral administration (injection) of antibiotics to successfully cure quarters infected with S. aureus. Likewise, extended therapy, which involves prolonged drug administration, has improved cure rates against this organism. Nonantibiotic approaches to treatment have included oxytocin injections, but relapse rates after this form of therapy can be unacceptably high. Dry or nonlactating cow therapy is almost always more successful than lactational therapy because cure rates are higher and new cases of mastitis are prevented. To reduce antibiotic usage, selective dry cow therapy is becoming popular, and teat seals are appealing because they prevent new infections without having to rely on antibiotics.

Johnsongrass (Sorghum halepense) is a warm-season perennial weed in pastures and roadsides throughout central and northern Georgia. Populations may germinate from seed in spring after overwintering in the soil. However, Johnsongrass primarily emerges from dormant rhizomes in areas with a history of infestations. Rhizomes are belowground stems that produce daughter plants and storage reserves for new growth in spring. The persistence of Johnsongrass is primarily associated with extensive rhizomatous growth that enable populations to spread laterally and dominate areas by preventing desirable species from flourishing.

This circular provides concise and accurate information describing mosquito biology and behavior. The publication describes the history of mosquitoes in Georgia and ways to prevent mosquito-borne diseases. Mosquitoes affect a large segment of the public, and mosquito control is most efficiently conducted in an integrated manner. This information will help homeowners address mosquito problems on their own property and provide insight into the intricacies of larger, community-based control programs.

This circular provides a basic summary of the best management practices of integrated mosquito management. These practices begin with education and communication and progress through surveillance, source reduction, larviciding, and adulticiding. The circular presents guidelines that communities can use to help develop the most effective mosquito management program possible with the resources available. Using these practices will help to minimize pesticide exposure to pollinators and other non-target pests.
