Imidacloprid seed treatment provided significant reductions in oat aphid populations in all cereal varieties till 90 days after planting with populations naturally crashing by the 104 day after planting assessment. However there was no significant control of the rose-grain aphid with highest aphid pressure occurring at 104 and 111 days after planting. Interestingly the low rate of imidacloprid resulted in significantly increased rose-grain aphid populations at 111 days after planting in both the bread and durum wheat varieties. There was no consistent impact from the foliar insecticide application on rose-grain aphid populations in any cereal variety.
Barley yellow dwarf virus symptoms were significantly reduced in both the bread and durum wheat varieties when assessed at 119 days after planting. There was no clear impact from the foliar insecticide at the same assessment, 35 days after application. Both rates of seed treatment resulted in a significant yield increase in the bread wheat variety. There was no yield impact from foliar fungicide application. Yields were much lower than expected following lengthy delays to harvest due to prolonged wet weather.
