There is a potential for boxwood blight infections this Thursday and Friday  throughout ALL of NJ. Incoming rains, coupled with consistent temperatures may initiate boxwood blight infections this week.

  • It is time to begin protective fungicide applications in boxwoods throughout the state if you have not already done so.

  • If BWB is important to your business – Use the USPEST – PUSH Alerts – (click here) – to setup weekly email alerts. Create an account, watch the tutorial, and then set up your subscriptions. You select which locations (as many as you like), days you want to receive emails (pick Sunday/Monday), and what you would like to receive alerts about (BWB and a variety of other pests and diseases). Rutgers is not directly affiliated, however this is an incredible tool.

HIGH potential for Boxwood Blight this Thursday 4/6

There is a potential for boxwood blight infections this WEDNESDAY and THURSDAY throughout much of NJ – especially central regions. Thursday’s high temperatures coupled with prolonged periods of leaf wetness overnight will contribute to the spread of boxwood blight infections.

If BWB is important to your business – Use the USPEST – PUSH Alerts – (click here) – to setup weekly email alerts. Create an account, watch the tutorial, and then set up your subscriptions. You select which locations (as many as you like), days you want to receive emails (pick Sunday/Monday), and what you would like to receive alerts about (BWB and a variety of other pests and diseases). Rutgers is not directly affiliated, however this is an incredible tool. 

  • It is time to begin protective fungicide applications in high value areas if you have not already done so! 

  • Protective fungicide applications should remain in effect or be initiated immediately for Boxwood Blight in “Infection risk or High Risk areas”. 
  • If your area is not listed (throughout all of NJ please visit the USPEST.ORG Boxwood Blight Risk Model – CLICK HERE TO CHECK YOUR LOCAL PREDICTIONS

Immediate potential for Boxwood Blight 3/24 and 3/25 – First infection potentials

There is a potential for new boxwood blight infections this FRIDAY and SATURDAY throughout much of NJ – especially central regions. Increased temperatures and prolonged periods of leaf wetness will contribute to the spread of boxwood blight infections.

  • It is time to begin protective fungicide applications in high value areas if you have not already done so! 

  • Protective fungicide applications should remain in effect or be initiated immediately for Boxwood Blight in “Infection risk or High Risk areas”. 
  • If your area is not listed (throughout all of NJ please visit the USPEST.ORG Boxwood Blight Risk Model – CLICK HERE TO CHECK YOUR LOCAL PREDICTIONS

(input your area code – select closest weather station – check 7-14 prediction – click on graph / table)

These advisories are general in nature, change rapidly over time, are site-specific…therefore  Someone from your business should be using this risk model daily if boxwood is important to your financial stability– In 30 seconds you can have a better idea of boxwood blight (and other pathogen) activity in your immediate area! Please contact Tim Waller if you need help using this service (twaller@njaes.rutgers.edu), we want to help! 

Fungicides; 

  1. You very well may have these materials already applied as ‘cover-sprays’ – But – be mindful that protectant fungicides loose efficacy the more rain (or overhead irrigation) they are subjected to, and reapplication may be warranted.
  2. ROTATE between Fungicide Resistance Action Committee (FRAC codes) to avoid this pathogen becoming resistant to specific chemicals

Format: [FRAC code]: Chemical name (Trade names * no endorsement implied, other options exist)  

  • [M05]: Chlorothalonil (Daconil WS)
  • [M05 + 1] Chlorothalonil + Thiophanate methyl (Spectro 90WDG)
  • [11] Trifloxystrobin + [7] Fluopyram  (Broadform)
  • [11] Trifloxystrobin + [3] Triadimefon (Armada 50WDG)
  • [M03] Mancozeb
  • [12] Fludioxonil (Medallion WDG)
  • [3] Tebuconazole (Torque)BW

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.
