The cranberry field trip was quite interesting in spite of it being scorching hot and humid outside. In addition to learning about production practices, we saw several diseases, including a severe dodder infestation, Phytophthora root rot, funky flower, and fairy ring. Fairy ring is caused by a new Helicobasidium species which, along with being a plant parasite, acts as a mycoparasite and grows on rust as an alternate host. Management of the disease may be achieved through treating weeds with fungicides, which is the first time I have ever heard of using chemical control on weeds for anything other than killing them. Very unique system.
