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...
