UMass IPM Fruit Loop

By Hawkeye

Welcome to The UMass IPM Fruit Loop! While Hawkeye does most of the talking, this is a co-creation of weekly contributions from Fruit Team Extension Educators Jon, Elizabeth and Matthew. Extension and Stockbridge School of Agriculture's Dr. Jamie Piñero contributes weekly insect updates and integrated pest management strategies. Stockbridge School of Agriculture's Dr. Daniel Cooley is the team's resident plant pathologist and Dr. Duane Greene gives us the skinny on all things thinning and growth regulated. When we are extra lucky, we get a guest to join us. The possibilities are endless!

A Bitter Battle- Unpacking the Colletotrichum Complexes Causing Bitter Rot in the Northeast U.S.

A Bitter Battle- Unpacking the Colletotrichum Complexes Causing Bitter Rot in the Northeast U.S.

The UMass IPM Fruit Loop, led by the apple enthusiast Hawkeye, has returned with a focus on the bitter and intricate world of apple bitter rot. While bitter rot historically occurred sporadically in Massachusetts, it has become increasingly problematic. The pathogens responsible, part of the Colletotrichum complex, have a long history but were only recently identified as causal agents. In the Northeast, particularly in Massachusetts, C. fioriniae is the most commonly identified species causing fruit disease, alongside other pathogens affecting various plants. Understanding the appearance and progression of bitter rot lesions is crucial for accurate diagnosis, especially distinguishing them from other leaf spots.


Differentiating between Colletotrichum complexes is essential due to their varied climatic preferences and disease manifestations. The complexity extends to fungicide resistance, with some species showing resistance to certain chemicals. Despite efforts to manage bitter rot, challenges persist, including the lack of fully resistant cultivars and the evolving nature of pathogen knowledge. Strategies like orchard sanitation and targeted fungicide applications are recommended, but the increasing frequency of extreme rain events adds another layer of complexity to disease management. As the understanding of bitter rot evolves, continuous research and adaptation in orchard practices are necessary for effective disease control.

Off Season Fruitloop- Forecast Models and Decision Support Systems- Part 3

Short and action packed. This episode of the UMass IPM Fruit Loop takes you through a super duper quick review of just what it is we are talking about (erm... it decision support systems, y'all) and then a fairly comprehensive description of how to interpret apple scab risk forecast output from both RIMpro (https://www.rimpro.eu/) and NEWA (http://newa.cornell.edu/), two DSS currently available to use in the Northeast and Midwest U.S. Feel free to open up the NEWA link and follow along! Likewise, if you have a RIMpro account, this would be a good time to get a refresher. Side note, while NEWA is only available in the U.S, RIMpro is available for subscription services around the world.

In this episode, Hawkeye dives deep on key pathogen and insect pest life cycles to lay the groundwork for a larger discussion about what forecast models are, how they work and how models, and the decision support systems that implement them fit into an IPM program. This is the first in a multi part series. How many parts you get depends on just how long winded Hawkeye gets...
