Potato and Tomato Disease Forecasting

Growers who are interested in using disease forecasting models should chose the location from the report that is closest in proximity to their farming operation.
 
In addition, regularly check the Cornell NEWA website @http://newa.cornell.edu/ where this information is compiled from. From the NEWA site menu click on Pests Forecasts, select your weather station, and click on the specific disease, set accumulation start date, and a table of daily and total DSVs will be generated.

Kentucky’s Combine Checklist to Prevent Wheat Bin Pests

In anticipation of the beginning of combine season, please check the following  resources to minimize stored grain losses or quality deductions.

High humidity has prevailed throughout much of southern New Jersey since Mid-May with most days registering above 90 degrees relative humidity. The rain event beginning on May 27th brought and inch to two-inches of rainfall to some areas of Salem County where small grains are rapidly maturing and lanternfly nymphs in rosebeds are rapidly emerging.

Memorial Day weekend gave producers a three day window to mow, swath and rake hay for dry baling today and tomorrow before thunderstorms are forecasted. Remember, last year was a high grasshopper egg laying season. If you noticed a significant number of grass hoppers in hay swathing or wheat combining this month, be on the alert for increasing grasshopper pressure on all other crops going into the rest of the summer.

Are you familiar with the federal soil quarantine map, associated pests of concern

During soil testing season, we often get calls about what laboratory to send samples to and what to test for. You may not know that under certain circumstances USDA-APHIS may have a quarantine for a particular plant or animal pest that can be carried in soil, and movement of soil from that region is restricted and requires a permit. This includes all territories of the United States such as Guam, Hawaii, Puerto Rico, and the U.S. Virgin Islands. APHIS also restricts the movement of domestic soil from areas within the continental United States that are under quarantine for specific plant pests and adjoining countries. For example, currently soil cannot enter the U.S.  from Canada if from the following areas of Alberta: A farm unit and associated land located near the municipality of Fort Saskatchewan; and a farm unit and associated land located near the municipality of Spruce Grove; British Colombia: That portion of the municipality of Central Saanich on Vancouver Island, ease of the west Saanich Road; Newfoundland and Labrador: The entire Island of Newfoundland; and Quebec: The municipality of Saint- Amble.

The Federal Domestic Soil Quarantines Map provides an overview of the plant pest quarantines that affect the movement of soil. USDA recently updated their Federal Domestic Soil Quarantine Map on February 10, 2022 which is available as a pdf at:

https://www.aphis.usda.gov/aphis/newsroom/stakeholder-info/stakeholder-messages/plant-health-news/federal-domestic-soil-quarantine-map-2-10-22

This map contains a lot of information that is useful for producers, growers and consumers who are purchasing plant materials that may contain soil to be mindful of the presence of significant plant pests of concern that have not yet made it to New Jersey, and to do their part to not bring them here. While many are limited to infestations along the west coast and gulf coast, others are closer to home. For example, the golden nematode is a potato nematode that is quarantined in some parts of western New York State. The pale cyst nematode is another potato nematode of concern that is quarantined from a small area of Idaho and the island of Newfoundland, Canada.

Others like the imported fire ant continue to spread and are now found in hot spots in Alabama, Arkansas, California, Florida, Georgia, Louisiana, Mississippi, New Mexico, North Carolina, Oklahoma, South Carolina, Tennessee, Texas, Virginia, and Puerto Rico. Quarantine efforts thus far have been able to limit the spread of witchweed to locations in South and North Carolina.

If you have specific questions about bringing in soil from any of these areas denoted in this USDA soil quarantine map or about these quarantine pests, contact the USDA-APHIS NJ state office, state plant health director at (609) 259-5244 or for more contact information see https://www.aphis.usda.gov/aphis/ourfocus/planthealth/ppq-program-overview/sphd/new+jersey

Proceedings Book – Speaker Summaries for February 22-25th NJ Vegetable Meeting

Each year for the New Jersey Vegetable Meeting, Rutgers Cooperative Extension publishes a proceedings book with summaries of presentations given during the educational sessions. The 2021 proceedings book is now posted on the Rutgers Vegetable Online Resources webpage. All proceedings books dating back to 2009 are also archived on this site and can be found by scrolling down to the bottom left corner of the webpage.

The 2021 Proceedings Book is dedicated in the memory of William Roberts who passed away on May 21, 2020 at theTwo people in dress clothes age of 88. After completing his college degree at Rutgers, Bill served our country in the military until 1955 where he earned the rank of First Lieutenant. He then returned to Rutgers, Cook College, to teach and later became an Extension Specialist in Agricultural Engineering. Early in his career, he invented the air-inflated, double-layer polyethylene film system for covering the roof of a greenhouse. Today, approximately 65 percent of all commercial greenhouses in the United States use the air-inflated system. This innovation won Bill many awards and tremendous gratitude from the industry. On a personal note, Bill was most known for his tremendous faith and love for family; especially wife Dottie. For more information about Bill Roberts, please see the beginning pages of the proceedings book for 2021.

We hope you will take the time to read the summaries included in the 2021 proceedings book. Robin Brumfield, Rutgers Extension Specialist in Agricultural Economics, recommends that anyone participating in the “Know Your Numbers, Know Your Options” morning and afternoon sessions on Monday, February 22nd, utilize her proceedings summaries on pages 19-25 (morning session) and pages 42-47 (afternoon session) while attending.

Also of interest – to obtain an online copy the 2020-2021 Commercial Vegetable Production Recommendations Guide a free download is available on the Rutgers NJAES Publications website. The guide is the same as in 2020 and a “critical updates” document is also available online for changes – mainly pesticide recommendations updates.
