Sign up for eNEWA – grape disease and insect pest email notifications

By Dan Olmstead and Tim Weigle

eNEWA is a daily email notification system that provides summarized weather, disease and insect model information based on NEWA tools and resources found at http://newa.cornell.edu. Read this article to learn more.

Daily eNEWA summaries contain current weather and grape pest model information from one or more NEWA stations of your choice, delivered at times of your choice. Each eNEWA notification contains the following information:

eNEWA is a convenient way to get a quick overview of pest potentials for your vineyard operation without clicking through the NEWA website every day.  eNEWA is not meant to replace the NEWA website, but it does provide a quick and easy way to know if you need to visit http://newa.cornell.edu/ for a closer look. For example, if eNEWA reports a potential infection event for one of the grape disease models you can visit the model on NEWA to get additional management information specific to your site.

Sign up for eNEWA

Things to know when signing up for eNEWA

  • eNEWA notifications will start shortly after the growing season begins.
  • An eNEWA email notification is approximately 3 pages in length for each location chosen.

Once during the growing season and again after harvest, you will be asked to complete a short survey to assist NYSIPM, LERGP, and Cornell Cooperative Extension improve the eNEWA notification system.

NYS Mesonet: 2018 year in review

2018 marked the first year of collaboration between the Network for Environment and Weather Applications (NEWA), which is part of the New York State IPM Program at Cornell University, and University at Albany’s New York State Mesonet (NYSM). In March, ten data streams (table 1, figure 1) were established to link NYSM-generated weather data to the NEWA online agricultural decision support system, available for use by agricultural stakeholders across New York State. 2018 was successful, as demonstrated by metrics provided in table 2. 2019 is sure to attract more users to these locations on NEWA as awareness grows of their availability.

The successful collaboration between NEWA and NYS Mesonet was also featured as a showcase in the New York State IPM Program 2017-18 Annual Report. The report can be downloaded from this Cornell eCommons permalink:

NEWA degree day models

Let’s take a closer look at how degree days are used on NEWA. My last post explained what they are, how they are calculated, and why they are used. But where and in what ways can they be accessed?

Every NEWA weather station has a unique ‘home page’ (Figure 1). This is an easy way to access degree day models during the growing season. When you follow a model link from the station page, results are automatically generated using data from that location.

Figure 1. This is the station home page for ‘Ithaca Cornell Orchards’ in New York State.

Degree-day models are also accessible from the navigation drop-down menus (Figure 2). This method requires user input to specify the station and location of interest. This gives you an opportunity to explore historical data, which is not an option when a model is accessed from a station home page as described above.

Figure 2. NEWA degree day tools can be accessed from the navigation drop-down menus.

The NEWA degree day calculator is a popular tool (Figure 3). Once the state, location of interest, desired base model, and start date is specified, custom degree day calculations are generated. For example, when a pre-programmed model is not available you can use the calculator as long as you understand which base temperature is needed. For more information about the degree day calculator, read this great post from April 2016 that provides more details. https://blogs.cornell.edu/yourenewa/2016/04/08/new-degree-day-calculator-on-newa/
