Grape Disease Control 2018
GRAPE DISEASE CONTROL, 2018 Bryan Hed, Department of Plant Pathology and Environmental Microbiology, Penn State University, Lake Erie Regional Grape Research and Extension Center, North East PA 16428 ([email protected]) As many of you know Wayne Wilcox, who has annually provided us with an incredibly thorough grape disease management update each spring, has retired. Filling Wayne's shoes is going to be a tall task to say the least, and the search for his replacement goes on. For now, I will attempt to provide a brief summary of some of the pertinent changes in grape disease control that I hope will be useful for grape growers in the 2018 season. For consistency, I'll roughly be using Wayne's format from his previous newsletter from June of 2017. FUNGICIDE CHANGES, NEWS, & REVIEWS Here is some new, and sort of new information regarding grape fungicides in 2018. First, Aprovia/Aprovia Top. The active ingredient in Aprovia is solatenol (benzovindiflupyr), and while it does not represent a new chemical class for us grape growers (succinate dehydrogenase inhibitor or SDHI) it is one of those 'new generation' SDHIs that Wayne spoke of last year. The SDHI fungicides belong to FRAC Group 7, which also includes chemistries in products like Endura and Pristine (boscalid) and Luna Experience (fluopyram). Aprovia was available for use in most states last year, but has now been labeled for use in New York as well. As a solo product, Aprovia is very effective for the control of powdery mildew as trials in NY over several years have shown. -
Powdery Mildew of Grapes
report on RPD No. 773 PLANT December 2019 DEPARTMENT OF CROP SCIENCES DISEASE UNIVERSITY OF ILLINOIS AT URBANA-CHAMPAIGN POWDERY MILDEW OF GRAPE Powdery mildew is caused by the fungus Uncinula necator. This fungus was reported in North America in 1834. Powdery mildew occurs in most grape growing areas of the world. If not managed effectively on susceptible cultivars, the disease can reduce vine growth, yield, quality, and winter hardiness. Cultivars of Vitis vinifera and its hybrids (French hybrids) are generally much more susceptible to powdery mildew than are native American cultivars such a Concord. Symptoms Uncinula necator can infect all green tissues of the grapevines. The fungus penetrate only epidermal cells, sending haustoria into them to absorb nutrients. Although haustoria are found only in epidermal cells, neighboring noninvaded cells may become necrotic. The presence of mycelia with conidiophores and conidia on the surface of the host tissue gives it a whitish gray, dusty or powdery appearance. Both surfaces of leaves of any age are susceptible to infection (Figure 1). _____________________________________________________________________________ For further information concerning diseases of small fruits, contact Dr. Mohammad Babadoost, Extension Specialist in Fruit and Vegetable Pathology, Department of Crop Sciences, University of Illinois at Urbana-Champaign. University of Illinois Extension provides equal opportunities in programs and employment. - 2 - Young expanding leaves that are infected become distorted and stunted (Figure 2). Petioles and cluster stems are susceptible to infection throughout the growing season. Once infected, they become brittle and may break as the season progresses. When green shoots are infected, the affected tissues appear dark brown to black in feathery patches (Figure 3), which later appear reddish brown on the dormant canes. -

Cockburn Assistant Professor of Food Science Robert F. Roberts Professor of Food Science Head of the Department of Food Science Approved by: Dr. ii ABSTRACT Numerous studies have indicated that the wine microbiome could generate various volatile compounds which could lead to distinguishing and different wine characteristics. However, little research regarding the wine microbiome is investigating specific microorganisms and their role within the entire microbial community under a more comprehensive sampling method. Thus, in this study we conducted direct sampling from Central and Northeast PA wineries instead of using lab-scale production to study the effect of the wine microbiome on the wine metabolome. Resulting grape and wine samples were characterized by next-generation sequencing and headspace-solid phase microextraction-gas chromatography-mass spectrometry (HS-SPME-GC-MS). Collectively, the innovative sampling and experimental techniques provided a high-resolution picture of microbial dynamics and the resulting wine volatile profiles. Overall, we illustrated how microbial diversity and relative abundance of specific microorganisms change as fermentation progressed. Also, various wine volatile metabolites that are formed during the different fermentation stages were identified. -

Training Systems for Cold Climate Hybrid Grapes in Wisconsin
A4157 Training systems for cold climate hybrid grapes in Wisconsin A. Atucha and M. Wimmer Cold climate hybrid grape cultivars (e.g., ‘Marquette’, ‘Frontenac’, ‘La Crescent’, ‘Brianna’, etc.) differ from European grape (Vitis vinifera) cultivars in several respects and require separate consideration with regard to the most appropriate training system. This publication focuses on aspects to consider when choosing a training system for cold climate hybrid grapes. Introduction Choosing a training system The training of grapevines refers to the physical action of The choice of an adequate training system will be influenced by manipulating a vine into a particular size, shape, and orientation. the following factors. The main objectives of training grapevines are to: 1. Maximize the interception of light by leaves and clusters, Cultivar growth habit Cold climate hybrids have a broad range of growth habits from leading to higher yield, improved fruit quality, and better procumbent (or downwards) to upright, and the choice of training disease control; system should adapt to the growth characteristic of the cultivar. 2.

Wyoming Residents Grow Grapes for Wines, Jellies
UW Cooperative Extension Service April 2010 Page 3 Wyoming residents grow grapes for wines, jellies By Sandra Frost Bucking horses, coal mines, gas wells, and high, cold desert are images that come to mind first when asked about Wyoming. Grapes and wine are not near the top of the list. Grapes are successfully grown in Wyoming, though, at both the homeowner and commercial scales. Grape varieties may be suitable for juice, jams, and jellies, table grapes, or wine production. Grape variety research was done at the University of Wyoming Sheridan Research and Extension Center (SREC) over several years (www. uwyo.edu/uwexpstn/Sheridan.asp). Colorado State University bhas also conducted grape variety trials under conditions similar to Wyoming and makes variety recommendations (www.coopext. colostate.edu/TRA/PLANTS/fruit.shtml).

Matching Grape Varieties to Sites Are Hybrid Varieties Right for Oklahoma?
Matching Grape Varieties to Sites Are hybrid varieties right for Oklahoma? Bruce Bordelon Purdue University Wine Grape Team 2014 Oklahoma Grape Growers Workshop 2006 survey of grape varieties in Oklahoma: Vinifera 80%. Hybrids 15% American 7% Muscadines 1% Profiles and Challenges…continued… • V. vinifera cultivars are the most widely grown in Oklahoma…; however, observation and research has shown most European cultivars to be highly susceptible to cold damage. • More research needs to be conducted to elicit where European cultivars will do best in Oklahoma. • French-American hybrids are good alternatives due to their better cold tolerance, but have not been embraced by Oklahoma grape growers... Reasons for this bias likely include hybrid cultivars being perceived as lower quality than European cultivars, lack of knowledge of available hybrid cultivars, personal preference, and misinformation. Profiles and Challenges…continued… • The unpredictable continental climate of Oklahoma is one of the foremost obstacles for potential grape growers. • It is essential that appropriate site selection be done prior to planting. • Many locations in Oklahoma are unsuitable for most grapes, including hybrids and American grapes. • Growing grapes in Oklahoma is a risky endeavor and minimization of potential loss by consideration of cultivar and environmental interactions is paramount to ensure long-term success. • There are areas where some European cultivars may succeed. • Many hybrid and American grapes are better suited for most areas of Oklahoma than -
