Grape Sour Rot
Although grape sour rot can occur in drier climates, the disease complex tends to be especially problematic during wine grape ripening in wet, humid regions. Browning and disintegrating berries and the aroma of vinegar (acetic acid) are a few symptoms that characterize grape sour rot. Sour rot ultimately results in crop yield reduction as damaged berries often “shatter,” or fall off the clusters. Sorting out clusters with sour rot that are not suitable for winemaking causes a further reduction in return revenues as less wine is produced. Although it has only recently been a topic of defined research, sour rot is a prominent concern in Eastern U.S. vineyards as: (1) it is consistently observed in vineyards, particularly in white-berried cultivars; and (2) questions remain about how to best manage it, particularly with the threat of insecticide resistance development in targeted fruit flies.

Fescue Toxicosis in Horses
Tall fescue is the primary cool season perennial forage grown in the state of Georgia, and toxicity issues related to the grass can have significant impacts on equine reproduction. Tall fescue is the most heat tolerant of the cool season grasses due to a fungus that grows within the plant called an endophyte. This endophyte produces ergot alkaloids that can have negative effects on animals that eat the infected forage. The toxic effects of the endophyte can be successfully managed by eliminating the grazing or feeding of toxic tall fescue, as described in this publication.

This is a new annual guide for managing diseases, insects, weeds, and wildlife in bunch grapes in the Southeast. This regional integrated pest management guide provides recommendations based on information from the manufacturer’s label and performance data from research and Extension field tests. This publication is intended for use only as a guide. Specific rates and application methods are on the pesticide label, and these are subject to change at any time. This publication is a product of the Southern Region Small Fruit Consortium.

This publication summarizes the latest and most relevant information regarding the management of the bermudagrass stem maggot (BSM), including biological, cultural, physical and chemical mitigation strategies. In addition to information about how to control the pest, this bulletin provides detailed information about the history, identification, and biology of the bermudagrass stem maggot.

Parasite resistance is an increasing problem in livestock species, including horses. Equine deworming practices have historically involved a six-week rotational deworming schedule. However, these practices have led to parasite resistance to many of our available dewormers. This publication addresses the current recommendations for deworming based on fecal egg counts, including why parasite resistance is increasing and how and when to assess fecal egg counts in horses.

This publication will educate pest management professionals about pesticides and instill vigilance in their handling and use. In order to understand how to use chemical pest control products responsibly, PMPs must have a basic understanding of the various definitions associated with pesticides, be able to interpret labels and material safety data sheets (including principles of toxicity), be aware of their own
safety, understand the mode of action (i.e., how pesticides work) of the various active ingredients they use, and be aware of differences in formulation types.|

This publication contains information on Microdochium patch, an emerging disease in the state of Georgia. This circular contains the biology of the causal agent, as well as a detailed description of the disease symptoms (with detailed pictures), relevant up-to-date information on conditions favoring the disease, as well as cultural, genetic and chemical methods of control. The publication is aimed at turfgrass professionals, sod growers, consultants, county faculty, students, and the general public.
