Aphelenchus ritzemabosi is known as a serious parasite of greenhouse plants such as chrysanthemums and gloxinias but the number of records of its attacks on plants grown out of doors is increasing. Disease due to it has been observed in the open on chrysanthemums and dahlias in this country and in the present paper a new out-of-door host is added to the list of plants attacked by it.

Abstract A description is provided for Asperisporium vitiphyllum, a colonizer of living leaves, causing a leaf spot or brown leaf blotch and leaf drying. Some information on its habitat, dispersal and transmission, and conservation status is given, along with details of its geographical distribution (Africa (Morocco and South Africa), Asia (Armenia, China, Georgia, Iran, Iraq, Israel, Kazakhstan (Almaty oblast), Kyrgyzstan, Pakistan, Tajikistan, Turkmenistan and Uzbekistan), Europe (Moldova, Russia (Krasnodar krai, Leningradskaya oblast, Stavropol krai) and Ukraine)) and hosts (including Vitis vinifera).

Discochora yuccae sp. nov. and its conidial anamorph Phyllosticta yuccae sp. nov. and spermatial synanamorph Leptodothiorella notabilis Petrak & Ciferri are described. The fungus causes a leaf-blotch disease of Yucca spp. and is distinguished by the long, cylindrical asci and relatively large, ellipsoidal ascospores. New combinations in Discochora are made for nine species previously assigned to Guignardia (auct.) and occurring on Liliales. One new combination is made in Botryosphaeria.

Abstract A three year field trial was conducted using established apple (Malus cv. Crown Gold) and horse chestnut (Aesculus hippocastanum L.) to assess the efficacy of paclobutrazol (PBZ) root drenches against the foliar pathogens apple scab (Venturia inaequalis (Cooke) G. Wint.,) and Guignardia leaf blotch (Guignardia aesculi (Peck) VB Stewart). In the case of horse chestnut, pathogen severity of Guignardia leaf blotch was less (23–79%) in each of the three-year experimental periods in PBZ-treated trees compared to non-treated controls. Pathogen severity of apple scab was not affected during the first year after PBZ application; however, less (25–73%) disease severity was recorded in years 2 and 3 compared to non-PBZ treated controls. An increased PBZ concentration was associated with lower pathogen severity of both fungal pathogens. Irrespective of species, less pathogen severity in PBZ-treated trees was accompanied with greater leaf chlorophyll fluorescence (16–49%) values as measures of leaf photosynthetic efficiency. Marked differences in growth regulation between apple cv. Crown Gold (tolerant) and horse chestnut (sensitive) were recorded. PBZ applications resulted in less mean stem extension in both tree species but only reduced mean leaf size of horse chestnut. Based on the results of this investigation it is suggested that PBZ root drenches potentially offer a means of reducing the severity of apple scab and Guignardia leaf blotch for professionals involved with the nursery industry. However, where a zero pathogen control policy is required supplementary fungicide sprays would be needed. Similarly, the potential loss of aesthetics due to excessive growth regulation needs to be weighed against the benefits of pathogen protection and failure of PBZ to achieve total pathogen control may result in strong selection pressure for PBZ resistance in surviving populations.
