Comparison of Three Dispenser Distribution Patterns for Pheromone Mating Disruption of Paralobesia viteana (Lepidoptera: Tortricidae) in Vineyards

Over two growing seasons, Isomate GBM-Plus tube-type dispensers releasing the major pheromone component of grape berry moth, Paralobesia viteana (Clemens) (Lepidoptera: Tortricidae), were evaluated in vineyards (Vitis spp.) in Michigan, New York, and Pennsylvania. Dispensers were deployed in three different density-arrangement treatments: 124 dispensers per ha, 494 dispensers per ha, and a combined treatment with 124 dispensers per ha in the vineyard interior and 988 dispensers per ha at the vineyard border, equivalent to an overall density of 494 dispensers per ha. Moth captures and cluster infestation levels were compared at the perimeter and interior of vineyards receiving these different pheromone treatments and in vineyards receiving no pheromone. Orientation of male moths to pheromone-baited traps positioned at the perimeter and interior of vineyards was reduced as a result of mating disruption treatments compared with the nontreated control. These findings were consistent over both years of the study. Disruption of male moth captures in traps varied from 93 to 100% in treated vineyards, with the 494 dispensers per ha application rates providing significantly higher level of disruption than the 124 dispensers per ha rate, but only in 2007. Measurements of percentage of cluster infestation indicated much higher infestation at perimeters than in the interior of the vineyards in all three regions, but in both sample positions there was no significant effect of dispenser density on cluster infestation levels in either year. The contrasting results of high disruption of moth orientation to traps in vineyards that also had low levels of crop protection from this pheromone treatment are discussed in the context of strategies to improve mating disruption of this tortricid pes

Putting a Face on the NYS Grape IPM Program and Lake Erie Regional Grape Program Extension Team - A Multi-pronged Approach to Information Transfer

Providing up-to-date production information to the diverse demographics of the Lake Erie Grape Growing region is a challenge that has been met through the use of a number of electronic information transfer techniques ranging from web sites and electronic newsletters to digital videos.  However, the use of electronic information transfer tools has brought about concern over a ‘faceless’ extension program.  To ensure that a connection is maintained between the NYS Grape IPM Program, Lake Erie Regional Grape Program Extension team and members of the Lake Erie grape industry, weekly Coffee Pot meeting were held from May through the end of August at a different grower venue each week

Three Steps to Manage Grape Berry Moth

Part of the series Grapes 101.Grape Berry Moth can be a serious pest in some vineyards. In this Wine & Grapes U. blog post originally published by Penn State, Andy Muza discusses how to better manage for this pest throughout the growing season

LERGP Coffee Pot Meetings Provide Bidirectional Education

Informal Coffee Pot meetings held weekly during the growing season by members of the Lake Erie Regional Grape Program provide extension team members with the chance to learn about local conditions affecting grape production while growers are taking the information and seeing a positive return on investment for practices they implement in their vineyards

Something for Everyone: A Multi-Pronged Approach to Information Delivery

The demographics of growers in the Lake Erie grape industry makes it difficult to plan educational activities appropriate for this diverse audience. Because many newcomers are approaching grape growing as a part-time business venture in the beginning, attending traditional educational events such as meetings during the day or evening is often in direct conflict with their primary off-farm jobs. The type of timely, in-depth information growers need in order to make intelligent decisions during the growing season is not found in the traditional newsletters delivered through the mail. Moreover, some growers’ off farm work schedules may make contact with extension personnel difficult to schedule

A System Approach to Concord Productivity and Fruit Quality in the Lake Erie Production Region

Research-based IPM practices have been developed and modeled for grape pests on the Network for Environment and Weather Applications (NEWA) website.  The purpose of this project was to determine if adoption of cost-effective, research-based IPM practices could be increased through a daily email (eNEWA alert) and education of the resources available on NEWA.  Forty-seven participants took part in the beta testing of an eNEWA-grape alert.  An end of season survey found that 88% of respondents found the eNEWA-grape alert to be above average in usefulness overall with over 90% finding it to be great or above average in the implementation of their vineyard IPM strategy

Increasing Quality and Profitability in New York Vineyards Using NEWA, Cornell’s Weather and Pest Network

NYS IPM Type: Project ReportThe multipronged approach to grower training on the use of NEWA resources by the NYS IPM Program, in conjunction with Cornell’s regional and area Grape Program Extension Teams, has resulted in savings by New York grape growers from $1 an acre to over$50 per acre. NEWA, the Network for Environment and Weather Applications, is a free, web-based weather and pest model information system (http://newa.cornell.edu/). While it was well know across the grape industry that the research-based information found on NEWA could help growers in developing and implementing their yearly pest management strategy, there was a resistance on the part of the growers to access the web site. Using a combination of traditional and innovative information transfer tools, the project team was able to dramatically increase the number of growers that not only accessed the information, but implemented it as well
