| Abstract | Effects of Benomyl and Thiram on the soil microflora and some soil inhabitant fungi were studied using the_ soil (sandy loam) of the experimental field, Okayama University. Under field conditions, heavy application of Benomyl did not affect significantly the soil microflora. Thiram, however, reduced the fungal population in soil to 1/6 at the next day of treatment, but recovered to the normal level after 6 days. Under laboratory conditions, both fungicides did not affect soil microflora. Population of Benomyl-to lerant fungi was about 1/10 of the total fungi and increased slightly in the field soil by treatment with Benomyl at the later stage of experiment during June to October. Neither Thiram-tolerant fungus nor bacterium was found in both Thiram-treated and non-treated soils. A fungus highly tolerant to Benomyl was isolated and identified as Aspergillus versicolor, and found to not have the metabolic activity to degrade BCM. The absorption of BCM by the mycelia of this tolerant fungus, A. versicolor, was less than half of the BCM-sensitive one, such as Cladosporium harbarum. |

| Abstract | Cladosporium cladosporioides (Fresenius) de Vries and Cladosporium herbarum (Pers. ) Link ex Fr. were isolated from grape berries that had been commonly called 'black navel', and were found to cause the disease. In view of the colour of lesions that were observed most frequently at the stage of maturing, the disease was named brown spot of grapes. |

| Abstract | Fungi tolerant to an organochlorine fungicide, tetrachloroisophthalonitrile (TCPN), was selected and isolated from various soil samples, and examined for the activity to metabolize TCPN. The population of tolerant fungi was extremely large in the plastic house - soil on which TCPN has been used for six years to control diseases. This is probably due to the change of soil microflora owing to the decline of TCPN-sensitive competitors. Many tolerant fungi took up TCPN very rapidly from culture filtrate. Of ten tolerant isolates tested, two isolates, C-F- I and V-P-5, were found to metabolize TCPN. The metabolite was isolated in pure form by preparative TLC, and identified as trichloroisophthalonitrile by mass spectrometry. C-F-1 was identified as Aspergillus luchuensis and V-P-5 as Penicillium godlewskii. Namely, these soil fungi dechlorinate from tetrachloroisophthalontrile to trichloroisophthalonitrile. |

| Abstract | The endocarp of the fresh pea pod incubated with solution or suspension of agricultural fungicides, phytotoxic metabolites of plant pathogenic fungi formed the pea phytoalexin, pisatin. Among the compounds tested, cycloheximide, triazine, dichlone, phenyimercury acetate, UV degradation product of phenylmercury acetate, triphenyltin fungicides, and 3-hydroxy-5-methylisoxazole induced pisatin. Ophiobolin, a toxin from Cochliobolus mtyabeanus, and ascochitine, a toxic metabolite from Ascochyta fabae, also induced pisatin. The possibilities of the development of harmless plant disease control agents was discussed in relation- to the induced synthesis of phytoalexins. |
