Viability and germination of conidia of three Botryosphaeriaceae species which are important grapevine pathogens were significantly affected by exposure to different levels of sunlight and relative humidity (RH) After 7 h exposure to nonfiltered sunlight (UV) filtered sunlight (UV) and shade germination differed between light levels being 35 57 and 81 respectively and after 70 h exposure it was 0 21 and 65 respectively Nongerminated conidia were unable to germinate when placed in a moist environment indicating that they had been killed High RH favoured germination since 91 and 70 respectively germinated after 3 h in 100 and 97 RH However in 93 RH only 44 germinated by 24 h and in 84 RH no conidia germinated The inhibition of germination was temporary since replacement in a moist environment caused conidia to germinate Light and RH effects were similar for the three speciesDownloads
