Spotted lanternfly (SLF) hatch is ON in Southern and Central NJ – ALL New Jersey COUNTIES are now QUARANTINED

Spotted Lanternfly nymphs will be emerging now through the first week of May for Southern and Central New Jersey – reduce their population early in the nursery industry!

Two important notes:

  • Through conversations with nursery operators, state inspectors (NJDOA), and internal agent communications SLF hatch has begun, which indicates a critical time to knock down nymph populations with CONTACT insecticides.
  • The entire state of New Jersey is now within the SLF QUARANTINE!

Updated 2023 Pest Scouting Guides are up – Getting prepared for the season ahead

The updated Pest Scouting Guides are here, and have a few improvements that enable YOU to share what YOU are seeing in the field with RCE.

Please click, download, and print these scouting guides for use at your nursery, landscape, or conifer plantation. Once printed you can scan the QR at the top of document to link back to the digital copy. These are much larger documents than 2022, as they are sorted by GDD, NEW-Insect “Group”, and by NEW-“favored host plants”. 

Nursery and Landscape Pest Scouting Guide – Scouting with Growing Degree-days (GDD) 2023 (click here)

Conifer and Christmas Tree Pest Scouting Guide – Scouting with Growing Degree-days (GDD) 2023 (click here)

Refer to this post “Obtaining your local growing degree-days (GDD)” for additional information (click here)  or contact Tim Waller twaller@njaes.rutgers.edu for help.

It is important to note that the GDD ranges do not replace scouting and that many of these GDD ranges have not been validated in New Jersey and would greatly benefit from local feedback. Therefore you will notice a QR code at the bottom of the cover-page. If you scan this code it will take you to a form that asks for details about pest occurrence, host plants, any observations, and after you submit your comments it allows the user to upload photographs. This is also a great place to leave feedback on what you would like to see in future iterations (such as pictures…).

PLEASE REPORT – pest observations that deviate from the stated GDD ranges in the guides

PLEASE SHARE PICTURES OF PESTS – we are working to develop insect ID pocket guides and other resources for our NJ growers…but we need your help

LONT – Comment and Photo upload REPORTING LINK (click here) 

Conifer – Comment and Photo upload REPORTING LINK (click here) 

If you would like to interact with the raw data yourself or incorporate it more closely into your businesses needs download this data file (click here) (file will download once clicked!). Please note it is a Microsoft Excel file, that is protected / cannot be modified on all but the two sheets labeled “GDD ACCU”. If you would like help with this or a non-protected file please contact twaller@njaes.rutgers.edu.

 

Regular updates will be utilizing this resource throughout the 2023 season. Have a great Spring Season everyone.

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.

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.

Bagworm hatch & Boxwood Blight potential now through Friday

Boxwood Blight (BWB) Alert – Infection Potential (Now – FRIDAY) 

There is a potential for new boxwood blight infections throughout much of NJ. The end of week rains coupled with more mild temperatures, cloud cover, and prolonged periods of leaf wetness will contribute to the spread or worsening of boxwood blight infections.

Boxwood Blight Risk Assessment as of 5/24/2022
Region Location CODE 1-June 2-June 3-June 4-June 5-June 6-June
Southern Upper Deerfield NJ50 Very Low  Infection Risk Infection Risk Very Low Very Low  Very Low 
Central Howell / Freehold NJ10 Infection Risk Infection Risk Infection Risk Very Low  Very Low  Very Low 
Northern High Point NJ59 Infection Risk Infection Risk Infection Risk Very Low  Very Low  Very Low 
Check local boxwood blight risk here (CLICK HERE – input your area code – select closest weather station – check 7-14 prediction – click on graph / table)

 

ALSO: Volutella Blight is extremely common and readily mis-diagnosed as boxwood blight or vise-versa.

  • There is a free / open to the public seminar June 23, 2022 about this important disease. Boxwood International Seminar on Biology and Management of Boxwood Volutella Blight by Prof. Tom Hsiang, University of Guelph, Guelph, Ontario, Canada. Registration Link: Click here to register
