A new testing service is being offered to grain growers and advisers to determine the presence of insecticide resistance in green peach aphid (GPA) populations... The service is being made available through cesar with the support of the Grains Research and Development Corporation (GRDC) to assist growers in choosing the most effective product for controlling GPA... Anthony van Rooyen, of cesar, says resistance in GPA has escalated as a result of heavy reliance on insecticides...

A near-perfect start with good summer and autumn rain coupled with mild temperatures saw crops jump out of the ground... Insect pests including green peach aphid (GPA) and the resulting beet western yellows virus (BWYV or synonym, turnip yellows virus) and diamondback moth (DBM) both proved headaches for growers at different stages of the growing season... Mr Baker says the colonisation of DBM in canola crops this year looks to be at a lower level for much the same reason as the risk of GPA and BWYV is this year - a much drier summer and early autumn than last year and less of a green bridge on which to survive...

Green peach aphid has developed resistance to more insecticides than any other insect species... neonicotinoids are also quite commonly applied to a variety of Australian vegetable crops and are becoming widespread in grains crops as a seed dressing... The most recent survey funded through the gRdC, conducted in 2013, has found widespread and high levels of resistance to carbamates (pirimicarb) and synthetic pyrethroids (alpha-cypemethrin) across Australia...

Do not sow canola into desiccating weeds/canola volunteers; otherwise, aphids will move directly from the weeds to the emerging seedlings... Use seed treated with a neonicotinoid insecticide and ensure proper application and coverage of seed dressing for efficacy against GPA... In order to control GPA populations colonising older canola leaves, applications should be made before crop closure and by using appropriate spray technologies...
