Summary
A method, in which tuber cores, obtained from either naturally or artificially infected tubers, are used for isolating races ofP. infestans is described. The production of large quantities of inoculum, and the maintenance of cultures for long periods, are discussed.
Zusammenfassung
Es wird ein Verfahren beschrieben, bei welchem Kerne aus natürlich oder künstlich infizierten Knollen zur Isolierung von Stämmen vonP. infestans verwendet werden. Die Erzeugung grosser Mengen von Infektionsmaterial und die Instandhaltung von Kulturen während längerer Zeit wird erörtert.
Résumé
L'auteur décrit une méthode dans laquelle des coeurs de tubercules, obtenus à partir de tubercules infectés d'une façon naturelle ou artificielle, sont utilisés pour isoler des souches deP. infestans. La production de grandes quantités d'inoculum et l'entretien prolongé des cultures sont discutés.
