At Field’s End: The Pictures and Poetry of Plant Disease

This work contains images and poetry about corn and soybean disease. Until publication of this text, plant pathology acted as a parasite upon the goodwill of the written language. Now, however, verbs, nouns, and adjectives join with conjunctions and team up with run-on sentences to welcome lesions, sclerotia, hyphae, and ascospores to form a symbiotic assemblage of astounding articulations, subtle sayings, and mediocre mutterings. Poetry and phytopathology merged and were mixed, subjected to the pipettor of destiny, and laid upon the agar plate of fate. And this book is what has grown upon that little plate.

CROP 3106

Bacterial Leaf Streak of Corn

Bacterial leaf streak, caused by Xanthomonas vasicola pv. Vasculorum, was recently identified in Iowa. The disease has been found in field corn, seed corn, popcorn and sweet corn. Based on what we know about other bacterial diseases, the pathogen that causes bacterial leaf streak likely survives in corn residue and is spread by wind and rain/irrigation. The impacts on corn yield production are yet to be determined.
