Episode 122: Pests & Pathogens Retrospective (Part 3)

Jackie Hayden and Dede Terns-Thorpe are back with part 3 of our retrospective series about Pests and Pathogens . In this episode of Nature Calls: Conversations from the Hudson Valley , you’ll hear about some common issues New York gardeners face such as rust fungus, squash vine borer, fruit flies and the emerald ash borer (EAB).

We’ll start with a category of blisters, galls, and spots on leaves and trees that are caused by a rust fungus. Humid, warm weather creates an excellent environment for many plant pathogens grow. Rust fungi are among the most common pathogens.While most rust fungi will not kill their host plants, they can weaken them to the point of not being functional in the landscape anymore. Learn more as Master Gardeners, Dede and Jackie, delve into this category of pathogen.

If you care about preserving the environment, stay tuned as Jackie and Dede discuss the emerald ash borer, an invasive species that has caused significant damage to the ash tree population in North America, including New York State. They cover everything from the beetle's life cycle to the measures being taken to prevent further spread.

Next is a segment on a popular pest of zucchini and other members of the cucurbit family: the dreaded Squash Vine Borer. As one of the earliest insects to show up in the garden as a moth, it can wreak havoc if not caught early. Learn some tips and tricks to help avoid and manage problems.

Lastly, how can you tell if you have fruit flies or fungus gnats flying around your home? No, they are not the same things.Both are tiny but fruit flies are larger than gnats. If they are flying around your house plants, they are probably fungus gnats. Dede and Jacki help you tell the difference between them and also provide suggestions on how to get rid of them.

So this episode has a little bit of something about both pests and pathogens. By listening in, you will be armed with lots of information about how to deal with them.
