110 National Atmospheric Deposition Program (NADP) National Trends Network (NTN) sites in
this study
► samples filtered in entirety at NADP Central Analytical Laboratory
► filters desiccated, sealed in Petri dishes, and sent to Cereal Disease Lab (CDL)
► filters sonicated at CDL to remove spores
► CDL tests for Phakopsora pachyrhizi using nested real-time qPCR
► positive assay indicates presence of P. pachyrhizi spores in rain
Asian Soybean Rust, 2006
This map displays counties where P. pachyrhizi was detected in soybean or other legumes between January and the week ending 6 June. The map also displays where spores were detected in rain samples collected 3 weeksprior to the week ending 6 June (i.e., in rain occurring between 9 & 30 May).
