...blight (Helminthosporium maydis), though not yet so severe as last year's attack, has now spread on its wind-borne spores to 31 states. Flourishing in warm, wet weather, the pathogen reduces the size of kernels, weakens the stalks and rots the ears. Because farmers have enough feed grain to last for nearly a year, however, the blight probably will not noticeably affect the price of such foods as meat, milk, cheese and poultry...

The agribusiness entrepreneurs of California's San Joaquin Valley have had another good year in cotton. The peaches of Comus, Md., have rarely been juicier. Helminthosporium maydis-the wind-borne spore of Southern corn blight-has appeared in the richest corn fields of the American breadbasket, and the damage has been serious. Yet the U.S. will still have the third best corn crop in its history...
...breed oats resistant to Helminthosporium victoriae blight, Dr. Wheeler decided to copy the method of the bacteriologists. He reports in Science that he sprouted 100 bu. of oats (about 45 million grains), then doused the sprouted seeds with the toxin (poisonous secretion) of the Helminthosporium fungus, and later with the fungus itself. Out of the 45 million, 973 seedlings survived and grew. Thirty days later they were treated with all the other oat diseases, and 471 survived the second ordeal...
Handy Reference. In Washington, the Department of Agriculture put out a farm pamphlet on corn-leaf blight entitled: "Cultural and Pathogenic Variability in Single-Conidial and Hyphal-Tip Isolates of Helminthosporium Turcicum Pass...
