Aphid infestations can be reduced by heavy rain events or sustained frosts. Re-monitor paddocks after heavy rain before making spray decisions. Toxic to bees; do not spray directly or allow to drift onto blooming crops or weeds where bees are foraging. Where feasible, sowing into standing stubble and achieving early canopy growth to reduce bare ground can reduce the risk of aphid landings within the crop. Henry K, Bellati J, Umina P and Wurst M. 2008. Research indicates that early-season infestations may delay maturity but usually do not result in yield loss unless other factors are also present that enhance the injury. It has been developed to help growers effectively control this pest, while at the same time minimising the selection pressure for further resistance development. Apply when aphids first appear or when damage first occurs. Large numbers of green peach aphid occasionally occur on young, vegetative stages of canola. sustainability through science & innovation.
