The World Agricultural Supply and Demand Estimates Report

April 8, tune in to this live stream 12:05 pm EDT on the World Agricultural Supply and Demand Estimates (WASDE) prepared and released by the World Agricultural Outlook Board (WAOB).

The WASDE report is released monthly, and provides annual forecasts for supply and use of U.S. and world commodities of interest to NJ producers like wheat, coarse grains, and oilseeds. The report also covers U.S. supply and use of sugar, meat, poultry eggs and milk.

On April 8, the Secretary of Agriculture briefings on World Agricultural Supply and Demand Estimates (WASDE) report and the Crop Production report will be livestreamed for the first time at 12:05 pm EDT on USDA’s National Agricultural Statistics Service (NASS) youtube channel.

To watch, book mark this youtube channel link entitled Agricultural Statistics Board Briefing and take note of the commentary in the left hand tool bar. https://www.youtube.com/playlist?list=PLm8HaeFw1A1h0onChnDCLkYgMSxEnpsOk

In-Person Private Applicator Exam Scheduled

Rutgers Office of Continuing Professional Education has announced an in-person session of the Private Applicator exam, exclusively for our farmers and growers, to be hosted on Wednesday, April 6 at the Burlington County office of Rutgers Cooperative Extension at 2 Academy Drive, Westampton, NJ 08060.

Each session (10:00 am and 12:30 pm) can accommodate up to 30 people, so if the demand is there, 2 sessions will be held that day. Only private applicator exams will be offered for this in-person testing event.

All examinees must be preregistered by the end of the day Monday, April 4 (details below), no walk-ins are allowed and no refunds will be given. If you register for April 6 and do not come to take the exam you will have to re-register and pay again.

All examinees must be registered ahead of time in PACER. Growers should register for an online exam, pay the $50 fee online, and then contact Jill Sullivan by phone at 848-932-7443 or by email by the end of the day on Monday, April 4 to say they want to take the exam in-person. Jill will provide registered growers with the time of the exam and location. This will also allow Jill time to create the exam answer sheets for Wednesday, April 6 and create a registration list.

For those who need help registering in PACER, there will be a second date announced for later in April, again at the Burlington County RCE office. Jill has created a registration document that you can print out, complete, and fax to Jill at 732-932-1187 or complete the information requested in the MSWord document and then email the completed form to Jill at pacer@njaes.rutgers.edu and she will register the grower and then call for the sensitive information (SSN and credit card information). The registration form is currently available through your local RCE office.

Thanks to Melissa Bravo, RCE of Salem County, for inquiring for an in-person test opportunity for our growers, to OCPE for accommodating this request and offering this opportunity for our growers, and to Burlington County RCE for hosting these exams.

Allium leaf miner update: 03/31/22

Allium Leaf Miner (ALM)

Many weather stations in southern and central counties have exceeded 250 growing degree days (GDD) base 39˚F within the past week.  39˚F is close to the lower developmental temperature (38.3˚ F) which our colleagues at Penn State recommend for predicting the first emergence of ALM adults.  Last year, initial feeding/egg laying scars were detected within a few days of local weather stations recording the 250 GDD threshold.  Limited inspections (Hunterdon, Morris counties) have not revealed scars yet, but feeding and egg laying is sure to come with the next series of warmer days.   Growers in southern counties may reasonably assume there is ALM activity in their area currently.

Growers should consider initiating the control method of their choice at this time.  Affected crops include chives, scallions, garlic, onions and leeks.  Look for neat rows of white spots descending from the upper tips of allium leaves (see photo at left).  Initial injury often occurs on the tallest leaves.  Under warmer, less breezy conditions, adults may be seen near the tips of leaves (see photo of adult at lower right).

Floating row covers, kept on until this flight ends will help minimize access to plants.  Insecticide applications targeting adults may be helpful as well, although frequency of applications is uncertain.  Spinosyn materials (Radiant, Entrust (OMRI approved)), pyrethroids (Mustang Maxx, Adult allium Leaf MinerWarrior), neonicotinoids (Scorpion, Venom), the diamide Exirel (section 2ee recommendation) and the insect growth regulator Trigard are labeled for miner control.

Adult activity and observations of feeding will be reported on in the IPM Update as they occur.  At this time, all growers should prepare to respond to the first adult generation.  We will deploy yellow sticky cards and attempt to identify the end of the first flight so that growers know when the risk of infestation has abated.

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
