Auf Einzelschlägen werden Symptome durch die Fritfliege beobachtet.
Der Zeitpunkt des Auftretens dieser ist schwer zu bestimmen. Somit ist auch der optimale Applikationszeitpunkt für eine mögliche Anwendung schwer festzulegen. Zugelassen sind Pyrethroide im BBCH 11-13 des Getreides.
Nach Sichtbarwerden der Schadsymptome ist eine Behandlung meist nicht mehr sinnvoll.
