Effects of chemicals and microbial antagonists on nematodes and fungal pathogens of citrus roots

摘要

In pot and field experiments in naturally infested soil, commercial products formulated with microbial antagonists, applied to soil, performed poorly against the nematodes Tylenchulus semipenetrans and Paratrichodorus lobatus, and the root rot fungi Phytophthora nicotianae and Pythium ultimum on citrus, compared with the conventional chemicals aldicarb, cadusafos and metalaxyl.
