摘要： Effects of sixteen chemical pesticides on conidial germination of C. thromboides and P. nouryi were investigated at two concentrations (R and 0.2R, where R=the lowest manufacture's recommended concentration for field use). Of the fungicides tested, propamocarb hydrochloride did not significantly affect conidial germination of C. thromboides , but at R it completely inhibited conidial germination of P. nouryi . At 0.2R of procymidone, iprodione, haloxyfop-methyl and fenoxaprop-p-ethyl, conidia of C. thromboides had some germination after 24 h, although they entirely restricted conidial germination of the fungus at the concentration of R. Tribenuron-methyl, one herbicide, had no adverse effect on conidial germination of C. thromboides and P. nouryi after 6 h at the two concentrations, whereas the other seven herbicides were strongly antagonistic to P. nouryi, except for carfentrazone-ethyl at 0.2R.
