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

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.
-
It is time to begin or continue protective fungicide applications in high value areas if you have not already done so!
- My BWB alerts will be less frequent over the summer, given the importance of other issues, and the availability of the Boxwood Blight Risk Model that will give you hyper localized predictions. CLICK HERE TO CHECK YOUR LOCAL BWB PREDICTIONS (takes 2 minutes and can save a crop or installation)
| 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

Bagworm hatch is upon us in Southern NJ and will soon be /already the case throughout NJ. Please be ready to control these insects during the VERY SHORT treatment window.

| Conifer mostly, many minor hosts | Bagworm | Thyridopteryx ephemeraeformis | 600 | 900 | RU | Larvae (early instars) – ONLY CONTROL WINDOW |
| Region | Location | Station | Date (600 GDD) | Date (900 GDD) | Treatment window | Bagworm Hatch – Predictions only, SCOUTING is critical! Treat as soon as larvae detected. |

Tree Fruit IPM Report for April 18, 2022
Evaluating Freeze Damage in Tree Fruit: The subfreezing temperatures on the morning of April 18 may have caused some natural thinning across the state. Any physiological damage that is not visible now will appear as the season progresses. A helpful guide for evaluating fruit damage can be found in the Intermountain Tree Fruit Production Guide.
Tree Fruit Phenology: Tree Fruit Phenology remains advanced, but development is slowing. In southern counties all peach orchards are mid to late bloom. Redhaven was at approximately full bloom on April 6, and was at Petal Fall by April 14. Plums are past shuck fall. Pears are full to late bloom. Red Delicious is just past 50% bloom. Sweet cherries are at about 50% bloom. [Read more…]
