Choosing the Perfect Christmas Tree – Tim Waller & Bill Errickson Podcast on Ask the Agent

Just in time for the holiday season! Please listen and SHARE with clientele.

Listen to our NEW “Choosing the Perfect Christmas Tree” podcast by clicking here

Agents Tim Waller (Cumberland) and Bill Errickson (Monmouth) were invited by Rutgers – Ask the Agent – hosts Steve Komar (Sussex), Bill Bamka (Burlington), and Lisa Chiariello (Sussex), to discuss all things Christmas Trees in New Jersey.

The goal of this podcast was to provide the general public with an idea of what it takes to produce a perfect Christmas Tree. We discuss tree production, why Christmas trees cost what they do, variety considerations, complexities of this industry, seasonal offerings, tree care (cut vs choose and cut vs B&B trees), the importance of supporting local communities and traditions, as well as offering some resources for current Christmas tree operators.

Please share this podcast with your clients, and keep an eye for more podcasts to come.

Virtual Pesticide Recertification Credit Series – Horticulture 3x Sessions

Sessions hosted by Tim Waller and Bill Errickson – through RCE of Cumberland County

Individual Sessions – October 13th (Th), 20th (Th), 26th (W) 6-7:00pm (Login @ 5:30pm)

Please join us as we discuss topics applicable to all horticulture applicators – the classes of chemistries we use, which to use under various circumstances, and safe handling thereof. These sessions are valuable to our general understanding of IPM tactics via a deeper understanding of the tools available to us.

NOTE: These free virtual sessions (on Zoom) will count as “in-person”, meaning all attendees will receive offered CEUs if they: have a live video feed (and are visible) and upload a government issued photo ID + NJ Pesticide license prior via a secure Rutgers Connect folder (follow directions below, only the agents will have access to information for verification). This approach avoids the 25% online credit restrictions previously in place for those with licenses NOT expiring 10/31/2022.

Government issued photo ID and NJ Pesticide License upload:

  • Click here to upload BOTH your government issued Photo ID and Pesticide License prior to the meeting
  • Upload directions: If you click on the photo ID upload link using a smart phone/tablet you will have the option of simply taking a photo of your ID and uploading it directly into the system. Otherwise, you can scan a copy of your photo ID into a computer and follow the directions at the upload link. If you are unable to upload documentation prior to the meeting, please contact Tim Waller for assistance (twaller@njaes.rutgers.edu).
  • Please upload files of your photo ID and applicator license to the link above as; “Last name_ First_ Photo ID” AND “Last name_ First_ Pesticide License”

Sessions: (You must register for each session individually, but only need to upload ID material one time)

Date:   10/13/2022 (Thursday)

  • Click here to register for 10/13 (TH)
  • How Chemicals Work and Which to Use (Tim Waller, Ph.D. RCE – Cumberland Co.)
  • Tim Waller will be discussing the various types of chemistries and classes thereof that are available for use in comestible agriculture to horticulture to right-of-way to green industries when treating some form of pest (diseases, insects, weeds, etc.). He will explain how these materials behave in or on plants, their effects on pests, when to use which materials, proper handling and safety considerations, and concepts of pesticide resistance that will ultimately lead to better chemical stewardship.
  • CEUs: CORE-2, 1A-2, 3A-2, 3B-2, 6B-2, 8C-2, 10-2, PP2-2

Sanitation basics, chemical types, and locations where to best utilize sanitation approaches, will be covered. Sanitizing chemistries and pesticides will be highlighted throughout this presentation and will focus on proper handling and safety as many of these compounds are potentially dangerous. Throughout the presentation pest or plant life cycles will be discussed to demonstrate implementation of sanitation techniques.
  • CEUs: CORE-2, 3A-2, 10-2, PP2-2

Welcome to the Christmas Tree PPA – Pest Scouting Guide Resources

Over the coming season we will be adding timely posts about pests, diseases, pesticides, and related agriculture updates that may need to be acted upon urgently. Additionally, we will be adding detailed information about particular issues to facilitate a better understanding moving forward. Please reach out to Tim Waller, Bill Errickson, or your local county agent if there are topics you would like to see covered through this system.

Pest Scouting

We have been working to develop pest scouting guides that utilize growing degree-days to help you better schedule and implement your IPM, scouting, and spray schedules.

If you are unfamiliar with growing degree-days (aka GDD or GDD50) Refer to this post “Obtaining your local growing degree-days” for additional information (click here!) 

Please download or print the Conifer Pest Scouting Guide and supplement below 

 

Thank you all very much for your continued support of Rutgers Cooperative Extension

July Pest Scouting Nursery, Landscape, and Christmas Trees – Key borer and scale insect control timings

Pest Scouting – Please refer to these documents for a full listing of insects pests for your area corresponding to growing degree-days (GDDs). 

Quick look guides for July (Borers and Scales) and (All other) 

Contact if seeing insects at different times: twaller@njaes.rutgers.edu (or call the Cumberland County Extension Office – 856-451-2800)

The following key groups of pests will be active, vulnerable, or otherwise treatable during the next month throughout most of NJ. Here, scale insects and borers with key life stage events during the 1000-2500 GDD timeframe are discussed. Note there are many other insect pests present this time of year so please view the pest scouting guides above for your particular needs.

Projected GDD50 Accumulation as of July 13 2022 Note: Growing degree-day values utilize daily average air temperatures with a minimum temperature threshold (a.k.a. ‘base’) of 50F = GDD50 (max. temp. threshold set at 95F). These values are accumulated from a biofix date, such as January or March 1st in the NE USA. Provided GDD50 are scouting ranges and should be truthed.
