Nineteen crosses were carried out in vitro between seven and nine isolates of Phytophthora infestans originating from potato and tomato, respectively. Oospores were produced abundantly in all but two crosses, but oospore germination was generally low

A total of 134 isolates of Phytophthora infestans were collected from potato and 42 from tomato fields in Switzerland and France in 1996 and 1997, and compared with isolates from other countries. The structure of the populations was analysed phenotyp

Developing shoots of grapevine (Vitis vinifera cv. Kerner) were inoculated with conidia of the powdery mildew, Uncinula necator, at well-defined phenological stages of the host to provoke the development of flag shoots in the field and to investigate

Wheat seedlings ( Triticum aestivum L. cv. Arina) contained mainly sitosterol and campesterol as the principal sterol compounds (71 and 21% of the total amount of free sterols, respectively), whereas stigmasterol (3%) and other unidentified sterols (

This paper provides evidence that the systemic resistance induced by dl -3-amino-n-butanoic acid, β-aminobutyric acid (BABA), against late blight in tomato is associated with the systemic acropetal translocation of BABA in the plant. Thus, when 14 C

Systemic resistance was induced in tomato by infecting the lower leaves with Phytophthora infestans . The level of this resistance increased over a period of 7 days from induction and stayed at the elevated level for at least a further 7 days. Change

[ 14 C]Cymoxanil was applied to either the root system or to the foliage of tomato plants and its uptake, translocation and degradation was followed using autoradiography, combustion and thin-layer chromatographic analyses of water or methanolic extr
