Twenty-five native grass species and 20 introduced forage grasses were tested for susceptibility to Peronosclerospora sorghi in Thailand. Sorghum nitidum, a native species, was susceptible to systemic infection. The native grass Themeda villosa was partially susceptible because only its lower leaves became systemically infected. Also tested was Zea diploperennis, which was susceptible.
