Abstract
A powdery mildew ( Erysiphe sp.) occurred on greenhouse‐grown tomato crops in southern England in 1987. White pustules appeared on the upper surfaces of leaves of affected crops and only rarely on the under surfaces. In greenhouse experiments, stems were very severely affected. In host range studies 19 tomato cultivars and six breeders' lines were susceptible as well as Nicotiana tabacum. N. xanthi. Solanium melongena, S. pseudocapsicum, S. tuberosum, Datura stramonium and Petunia hybrida. Conidia germinated readily at 15, 20 and 25 C and were viable for 2 days in the laboratory and at least 6 days in the greenhouse. The disease was well controlled by a range of fungicides including benomyl, bupirimate, carbendazim, chlorothalonil, fenarimol and pyrazophos. All of these except pyrazophos are approved for use on tomatoes in the UK. The pathogen was very sensitive to low concentrations of benomyl and fenarimol but less so to bupirimate.
