The germination rate of wheat powdery mildew (Erysiphe graminis f. sp. tritici) conidia was examined by means of an apparatus which permitted continuous observation of the germination of each sample throughout the experiment. Germination experiments were conducted at constant RH and at temperatures ranging from +5° to +30° with intervals of 2.5°. Germination was fastest at +20° and +22.5° C. The highest germination percentage was obtained at +17.5° C.
