Field surveys for canola diseases and flea beetles were conducted in the major canola growing areas of North Dakota from 2003-2005.  Fields were surveyed in the swath.  Approximately one field was surveyed for each 2,000 ha of canola planted the previous season in each county.  A total of 50 plants (10 plants in 5 different sites per field) were evaluated for diseases in each field.  Incidence and severity of blackleg (Leptosphaeria maculans), Sclerotinia stem rot (Sclerotinia sclerotiorum), and other diseases were recorded for each surveyed field.  Statewide averages of blackleg and Sclerotinia stem rot ranged between 11 – 14% and 4 – 8% for blackleg and Sclerotinia stem rot, respectively.  Flea beetles, principally the crucifer flea beetle, Phyllotreta cruciferae (Goeze), are the most economically important insect pest of canola in North Dakota.  A total of 20 sweeps with a net (4 sweeps in 5 different sites per field) were used to measure the number of flea beetles present per swath field.  Flea beetle populations were higher in 2003 (average number of 50 flea beetles per 4 sweeps) than 2004 (average number of 9 flea beetles per 4 sweeps) and 2005 (average number of 10 flea beetles per 4 sweeps).  Information on the population level of summer flea beetles is used for forecasting the upcoming spring infestation risk, and for developing appropriate grower education programs for areas with moderate-high flea beetle risk.  Numerous IPM scouts, area extension specialists and county extension agents in northeastern North Dakota were involved in conducting these cooperative surveys.
