Biological activity and systemic translocation of the new tetrazolyloxime fungicide picarbutrazox against plant-pathogenic oomycetes.

The results showed that picarbutrazox markedly inhibited the important plant oomycete pathogens including Phytophthora spp., Pythium spp. and Phytopythium spp.. It also displayed excellent protective, curative and systemic translocation activity. Picarbutrazox thus has significant potential for preventing and controlling diseases caused by oomycetes. © 2024 Society of Chemical Industry.
