Leaves of Afzelia xylocarpa infected with rust were collected from the National Corn and Sorghum Research Centre, Rai Suwan, Nakhon Ratchasima, northeastern Thailand in January 2011. The rust was identified as Phakopsora pachyrhizi based on morphological and DNA sequence data. Afzelia xylocarpa represents a new host genus and species for this rust fungus, which is commonly known as Asian soybean rust.

The rust Prospodium appendiculatum was collected on Tecoma stans, commonly called yellow bells or yellow trumpet bush, from northeastern Thailand. The identification was based on the morphology of uredinial and telial stages. This is the first report of this rust fungus in Thailand where T. stans is often cultivated as an ornamental.
