The common armyworm Leucania convecta (Mythimna convecta) was a serious problem for NSW rice producers during the 2011/12 and 2012/13 rice seasons, particularly in the Murray Valley. Major crop damage occurred, partly as a consequence of inadequate crop monitoring in the period leading up to harvest, and also for logistical reasons, principally a shortage of aircraft and poor weather conditions preventing prompt chemical application.
