Plant diseases are all around us, often wreaking havoc on our favorite plants. And yet, plant diseases can be intriguing, fascinating, and often beautiful as well. Limerickettsia: A Plant Pathologist's Book of Verse tells whimsical and informative tales of plant diseases, past and present, told through the magic of limericks. The book contains 52 plant disease-themed limericks with accompanying prose descriptions, and full-color photographs and original artwork. The book includes limericks about plant diseases caused by all of the major types of disease-causing organisms (i.e., fungi, bacteria, viruses, nematodes, phytoplasmas and even parasitic plants), as well as limericks about things that look like plant diseases (e.g., bird's nest fungi, slime molds, stink horns) but are not. For each disease, readers can learn about what the plant disease looks like, how the organism that cause the disease does its thing, and tips on plant disease control. For some of the diseases (e.g., grain rusts, late blight of potato, Dutch elm disease), there are also tidbits about how the diseases have impacted human history.
