Abstract ブドウ褐点病防除のための農薬のスクリーニングを行なうとともに,発生生態の観察結果を含めて本病の防除施策について論じた. 供用農薬のなかでは,ベンレート,サニパー,DF125が有効であった. 自然発生,特に汚果の防止には硫酸ニコチンの混用が有効であった. 外気の直接導入を避けるような温室出入口の構造改善,室内浄化,誘枝線の更新,過湿の回避などが有効な技術的な防除策と考えられた。

Abstract 純寄生性病害の感染成立に中心的役割を演ずると考えられている吸器の性質を明らかにするために,オオムギうどんこ病菌の吸器形成過程における吸器壁のキチン質の生成に関して組織化学的に検討した. その結果,吸器壁はキトーサン反応陽性で,菌糸壁と同様キチン質がその骨格をなしているものと考えられる. さらに,経時的な検討の結果,感染初期に形成される吸器原基において,すでにキチン反応が陽性であり,キチン合成系の活性化は,吸器機能発現のための一つの重要な過程であると推定される。

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.

Abstract An elicitor of pisatin accumulation was isolated and partially characterized from spore germination fluid, mycelial extract, and cell wall preparation of a pea pathogen, Mycosphaerella pinodes. The elicitor was found to be a polysaccharide or glycoprotein and the active component was composed of glucose. The approximate molecular weight was 70,000 daltons. This elicitor elicited pisatin accumulation in pea leaves at a concentration of 10 ug/ml and the maximum activity was ca. 350-400 ug/ml, but did not elicit phytoalexins in soybean, bean, and red clover. High molecular weight preparations from the mycelial extract and mycelial wall of Mycosphaerella melonis and Stemphylium sarcinaeforme, nonpathogens of pea, elicited pisatin accumulation in pea leaves.
