Downy mildew disease caused by the fungus Sclerospora graminicola Schroet, causes yield losses across the millet growing zones of Nigeria. Identification of the source of resistance and gene actions controlling resistance is useful in developing appropriate breeding strategies. Therefore there was need to study downy mildew resistance in Nigerian elite pearl millet lines. Five pearl millet pare...

ABSTRACT A weather-based infection model for stem rust of perennial ryegrass seed crops was developed and tested using data from inoculated bioassay plants in a field environment with monitored weather. The model describes favorability of daily weather as a proportion (0.0 to 1.0) of the maximum possible infection level set by host and inoculum. Moisture duration and temperature are combined in...

Absract The diversity and community structure of arthropods in the primitive tobacco ecosystem in the South of Anhui province, China was studied. The investigations were undertaken from April to August 2012. The comparisons were undertaken using a combination of community assessment approaches, including morphospecies richness, the Shannon-Weaver diversity index, H', the Simpson dominance index...
