Pathogenicity of Oomycete Species to Different Hybrid Rootstocks.

Diseases caused by soilborne oomycetes are a limiting factor for the cultivation of spp., which makes the choice of a suitable rootstock a key factor. The objective of this study was to evaluate the pathogenicity of 12 oomycete species belonging to the genera , (), and (.

Susceptibility of Almond () Cultivars to Twig Canker and Shoot Blight Caused by .

Twenty-five almond cultivars were assessed for susceptibility to , causal agent of twig canker and shoot blight disease. In laboratory experiments, growing twigs were inoculated with four isolates. Moreover, growing shoots of almond cultivars grafted onto INRA 'GF-677' rootstock were used in 4-year field inoculations with one isolate.
