WATCH FOR UPDATES EVERY TUESDAY AND FRIDAY. Use LEGEND AT BOTTOM OF PAGE indicating average swede midge per trap/per day along with Swede Midge Management Guide at www.ontariocanolagrowers.ca for guidance in judging when swede midge treatment is necessary. For 1st treatment - use cumulative trap # of 20. For 2nd treatment and any subsequent treatments use average trap per day #. KEY TO STAY AHEAD OF SWEDE MIDGE. IF YOU SEE DAMAGE IT IS TOO LATE. Fields planted close to previous year canola or planted late will be particularly vulnerable to swede midge. Last Update July 28th 2014.
