Abstract

Elongation of germination hyphae ofSphaerotheca fuliginea on Czapek Dox agar with yeast extract continued for several weeks, resulting in the formation of hyphae with up to 30 cells. This permitted development of a method for measuring the effect on fungal growth in vitro of a number of fungicides and antimetabolites with known effect against powdery mildew diseases of plants.

Samenvatting

Na uitzaaien van conidiën vanSphaerotheca fuliginea op een agar medium, waaraan gistextract was toegevoegd, bleek groei van kiemhyfen zich bij een beperkt aantal conidiën gedurende enkele weken voort te zetten, waarbij tot 30 cellen werden gevormd. Dit verschafte een methode om de werking van fungiciden en andere verbindingen op meeldauwmycelium in vitro na te gaan. De resultaten werden vergeleken met die verkregen in sporekiemingstoetsen (Tabel 1).
