The first was the rapid spread of Uncinula necator, vine powdery mildew, following its identification in England in 1845. A search for control methods led, from the initial observation by Mr Tuker in England that sulfur was an effective treatment, to the development in 1855 by Bequerel of a fungicide application programme based on the use of a fine form of sulfur dust.

A high frequency of wheat powdery mildew isolates resistant towards quinoxyfen have been reported from Northern Germany [75]. Field isolates of Uncinula necator with reduced sensitivity to quinoxyfen were found in 2003 but the efficacy level under practical field conditions remained unchanged [76].
