White oat agronomic performance and cultivar reactions to leaf rust and leaf spot

Cultivar mixtures for the simultaneous management of multiple diseases: tan spot and leaf rust of wheat.

ABSTRACT Because of differences in life histories between Puccinia triticina, a highly specialized, polycyclic, windborne pathogen with a shallow dispersal gradient, and Pyrenophora tritici-repentis, a residue-borne pathogen with a steep dispersal gradient, wheat mixtures are expected to be more effective at controlling leaf rust than tan spot. The objectives of this research were to determine ...

Reactions of Open-Pollinated Sweet Corn Cultivars to Stewart’s Wilt, Common Rust, Northern Leaf Blight, and Southern Leaf Blight

The first commercially successful F1 hybrid sweet corn, Golden Cross Bantam, was released by Smith in the early 1930s (17). Today, over 600 sweet corn hybrids are available commercially in the United States and thousands of new hybrids are developed and evaluated each year. These hybrids display a wide range of phenotypic reactions to prevalent diseases (9), indicating a considerable amount of ...

Mycosphaerella leaf spot diseases

By the end of the 1980s, black leaf streak disease caused by Mycosphaerella fijiensis was present in all continents where bananas or plantains were grown, although distribution in some regions was limited to a few countries. In this presentation, the spread of the disease during the 1990s in several countries and regions, and the important socio-economic consequences are discussed. From 1990 to...
