Economic Aspects of Crop Pest Management and Monarch Conservation
… conserve Monarchs. The second chapter estimate soybean farmers' value of information provided by alternative configurations of a monitoring network for soybean rust (Phakopsora pachyrhizi). It shows that a network of 400 sentinel plots can maximize the expected profit of soybean farmers provided …

Construction and evaluation of infectious cDNA clones and analysis of packaging determinants of Soybean dwarf virus
Soybean dwarf virus (SbDV) is a phloem-limited, aphid-transmitted luteovirus that causes dwarfing of soybean plants. In the present study, infectious clones of two dwarfing isolates of SbDV were constructed, and methods for Agrobacterium-mediated inoculation of plants were standardized and used to …
