The Michigan State University Tree Fruit Pathology Lab has recently released 12 short instructional videos on a variety of subjects. Major diseases of apples and cherries are covered, including apple scab, fire blight, apple canker disease and cherry leaf spot. Separate videos covering fungicide resistance management and in-depth summaries of individual fungicide groups will also be presented.
The videos are available on YouTube through the channel called “Tree Fruit Pathology.”
Individual videos currently available
- Early season buildup of the fire blight pathogen Erwinia amylovora
- Fire blight – shoot blight development
- Fire blight – pruning shoot blight strikes
- Fire blight and cankers
- Biological control of fire blight
- SDHI fungicide premixes – resistance management strategies for the SDHIs
- Evaluation of SDHIS for control of cherry leaf spot, powdery mildew, and American brown rot
New apple canker disease in Michigan
- Blossom blast and bacterial canker on sweet cherry
- Chemical control options for bacterial canker of sweet cherry
Current plans over the winter months will be to upload an additional 10 to 15 instructional videos covering topics related to diseases and disease management, including:
- Multi-site fungicides for apple
- Single-site fungicides for apple scab management
- Reducing apple scab spore load
- Anilinopyrimdine fungicides for apple scab management
- Strobilurin fungicides for tree fruit disease management
- Second-generation sterol-inhibitor fungicides for apple scab management
- SDHI fungicides for apple scab management
- Use of Apogee for shoot blight management
In addition, we will be releasing additional videos as the 2013 season develops that will accompany our tree fruit pathology-related Michigan State University Extension News articles.
