This publication is intended for use only as a guide. Specific rates and application methods are on the pesticide label,…
- 2024 Southeast Regional Muscadine Grape Integrated Management Guide (AP 126-3) This 2024 update to the regional integrated pest management guide provides recommendations for muscadine grape production in the Southeastern U.S. Recommendations are 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,…
- A preliminary comparison between manual and mechanical pruning the muscadine juice cultivar 'Carlos' (B 1536) Results from this study are preliminary, as only 2 years of data have been collected. Research over longer periods of time will be more revealing about how mechanical pruning will impact the perennial crop yield and health of the vineyard. Mechanical pruning is an option for dormant pruning ‘Carlos’ in situations where labor is unreliable and/or there is a low labor-to-acreage ratio which preclude…
- Athena: A New Training System for Bunch Wine Grapes (B 1527) The Athena bunch wine grape training system was developed by the University of Georgia to increase crop yield in modest-yielding cultivars. The Athena is a divided-canopy system retrofit to the industry standard single-canopy trellising system with vertical shoot positioning. Athena training involves laying four canes and dividing the canopy through a series of cross arms fastened to the vineyard …
- Blanc du Bois (C 1274) ‘Blanc du Bois’ has made a significant contribution to wine production in southeastern regions where Pierce’s disease is prevalent. Though possessing resistance or tolerance to Pierce’s disease, Phylloxera, and powdery mildew, this cultivar is not without fault, and it does require an intensive integrated pest management (IPM) program. We cover here the major issues observed with this cultivar.
- Dormant Spur and Cane Pruning Bunch Grapevines (B 1505) This bulletin is intended to provide to provide both veteran and new growers an overview of commercially popular pruning strategies and a greater depth of understanding of the theory behind pruning method practice. Dormant pruning is an important vineyard management decision as it sets the crop level and canopy density before green tissues are present. Growers must take several considerations into…
- Grape Sour Rot (C 1212) 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. …
- Home Garden Series: Home Garden Bunch Grapes (B 807) Bunch grapes are often called “pod” grapes in rural Georgia since they produce large clusters of fruit. Georgia's climate is not well-suited to home garden production of European bunch grapes, but American bunch grapes and hybrids between the two species (French hybrids) grow well in Georgia. If grapes are well cared for and sprayed when diseases and insects threaten, you can expect yields of 20 t…
- Home Garden Series: Home Garden Muscadines (C 949) Muscadines are truly a fruit for the south. Although muscadines can be grown successfully in most parts of the state, they are best adapted to the Piedmont and Coastal Plain areas.
- Introduction to Wine Grape Trellising, Training, and Pruning Terms (C 1162) There are many ways to manage grapevine growth, and many grape-growing regions implement unique and preferred training methods. Vine growth management is achieved by applying a trellising system, which is a framework of metal cross arms, wires, and support posts that are used to direct grapevine vegetation to maximize fruit quality and production. Trellising and pruning combinations will sometimes…
- Pierce's Disease of Grape: Identification and Management (B 1514) Pierce’s disease (PD) may be the greatest threat to the growth and sustainability of wine grape industries in the Southeastern U.S. The first step to managing grapevine PD is understanding the threat of PD as dictated by the region in which vines will be planted. It is highly advised that PD-tolerant cultivars be planted if a vineyard will be established in a region of high PD-threat. Growers shou…
- Pruning Muscadine Grapes (C 1268) Many gardeners don’t realize how vigorously muscadines and grapes must be pruned each season in order to ensure good production. Quality equipment and care also is essential to maintain healthy plants. This video covers the basics of how to properly prune muscadines and bunch grapes. Correct pruning methods are essential for strong fruit production and must be performed annually at the proper time…
- Spanish Series: Manejo del Viñedo (C 1151-SP) 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 mane…
- Vineyard Canopy Management Series: Fruit Zone Management (C 1219) The “Vineyard Canopy Management Series” of Extension circulars reviews a number of canopy-management practices individually. Each circular advises how to effectively implement a canopy-management practice and why it is important to do so. The practices collectively known as “canopy management” aim to maximize canopy leaf exposure, maintain crop yield and quality, decrease disease, and improve vine…
- Vineyard Canopy Management: Shoot Thinning (C 1152) Shoot thinning is the first seasonal canopy management practice in wine grape vineyards, but shoot thinning is not implemented in muscadine vineyards. Failure to shoot thin results in a highly congested canopy characterized by reduced air flow, high humidity, and extended damp periods. Muscadines can generally tolerate such conditions without adverse effects. Wine grapes grown in crowded fruit zon…
- Vineyard Frost Protection (B 1490) The vineyard industry is growing across Georgia and across the Eastern United States. Frost is a perennial threat in these regions, and reducing frost risk can save approximately $48,000 per acre in return revenues. Since many growers new to the industry will be planting vineyards, it is important that they are aware of the risk of frost and ways to avoid it. This bulletin also serves as a good re…
- Viticulture Management (C 1151) This phenology-based viticulture management poster provides a reference for sound viticultural, disease, and insect management practices in a digestible format. Viticultural practices optimize vineyard health, profitability, and sustainability and improve crop quantity and quality. Like pest management, viticultural practices should be implemented in a timely fashion throughout the growing season …
- Watson Training System for Bunch Wine Grapes (B 1522) There are two main trellising system categories: divided and single canopy. Jerry Watson, a grape grower and owner of Austin County Vineyards in Cat Spring, Texas, developed the divided canopy “Watson System” in 2002 to solve some issues he was having with bunch rot management and harvest inefficiency in his ‘Blanc Du Bois’ and ‘Lenoir’ vineyards. By adding a series of cross arms and catch wires t…
- Winemaking at Home (C 717) This publication provides essential material and detailed instructions for successfully making wine at home. The information is designed for beginners who do not know where to begin and for experienced amateurs who run into difficulties.
