I have had a recommendation to spray aphids in wheat to prevent BYDV, as I expect many of you have. I avoid insecticides for all of the usual reasons, but it seems this one is needed. So what aphid predators are there about at this time of year that may be harmed ? I don't think there are many ladybirds about, never mind there larvae. Is an insecticide at this time of year as benign as it can be ?
