Sensitivity of Pythium spp. and Phytopythium spp. and tolerance mechanism of Pythium spp. to oxathiapiprolin.

This study showed that oxathiapiprolin had excellent activity against Phytopythium spp. but displayed a differentiated activity against different Pythium spp. ORP1s in Pythium spp. are positively related to the tolerance of Pythium species to oxathiapiprolin. © 2020 Society of Chemical Industry.
