Increasing temperatures = scout for insects pests! 2022 Nursery and Conifer Pest Scouting Guides HERE

With the increases in daily temperature averages expected over the next week for the southern and central areas of NJ, pest scouting should commence on commercially important ornamental crops and landscapes. Typically, in our region, growing degree-days (GDD50) are counted beginning March 1st (known as a biofix date), however this year by March first we may see degree-day accumulation approaching 20+. Therefor scouting efforts should be commenced, especially in conifers. 

We have compiled the GDD resources into one single document – please download and print multiple copies of this for yourself and employees in efforts to best scout for these insect pests. These guides do not dictate when to spray, rather they inform scouting ranges for insect pests, vulnerable life-stages, and overlapping timeframes for multiple troublesome pests.

Nursery and Landscape Pest Scouting Guide 2022 PDF (note this contains conifer pests as well)

Conifer Pest Scouting Guide 2022 PDF

Refer to this post “Obtaining your local growing degree-days” for additional information 

We will be making regular announcements throughout the season, however we wanted you to have this beta-version of the compiled growing-degree day information. This will be updated and modified throughout the season – PLEASE let me know what difference you are seeing in the field so we can continue to make this resource better for all of us.

Chlorpyrifos: Revocation of All Food Tolerances Effective February 28, 2022

In August 2021, EPA released a final rule revoking all “tolerances” for chlorpyrifos, which establish an amount of a pesticide that is allowed on food. In addition, the agency issued a Notice of Intent to Cancel under the Federal Insecticide, Fungicide, and Rodenticide Act to cancel registered food uses of chlorpyrifos associated with the revoked […]

EPA Requires Cancellation of Pentachlorophenol to Protect Human Health

[Friday 2/4/2022]. Today, EPA issued a final registration review decision requiring the cancellation of pentachlorophenol, a wood preservative used primarily on utility poles. During the registration review process, EPA found that given the emergence of viable alternatives, the risks pentachlorophenol poses to workers’ health outweigh the benefits of its use. Following EPA’s March 2021 proposal […]

2022 NJ Ag Convention & Trade Show Update – Pesticide Credits Posted

The final program agenda for the educational sessions of the 2022 NJ Ag Convention & Trade Show with assigned pesticide re-certification credits has been posted at the Vegetable Growers Association of NJ website:  vganj.com on the ‘Schedule’ tab. Pesticide credits will only be issued to those attending and signing the roster in the educational sessions in Atlantic City. There are no options for viewing presentations online.

There has been some confusion about COVID-19 protocols for attending. The NJ Department of Agriculture/State Board of Agriculture sessions and meal functions (luncheons and banquet) will have strict masking and pre-testing requirements to enter those rooms per memo from Secretary of Agriculture Doug Fisher earlier this week. There will be some on-site testing opportunities available in case you are unable to be tested before getting to Atlantic City.

However, these mandates are not requirements, though highly recommended, for attending the educational sessions or the trade show portions of this event. There will be some masks available throughout the conference venue.

Hope to see you there!
