VT Apple IPM: Fire Blight Alert

I’ll follow up with more details later- this announcement is meant as a notice in case anyone like myself needs to get their hands on some streptomycin today- but the NEWA fire blight models are predicting increasing likelihood of infection over the weekend as temperatures climb. If you have open blooms, be prepared to cover in the event of rain or to add strep to your spray tank if applying thinning sprays in the next few days. I’ll reach out later today with details on thinning, the insect situation, and disease management.
