Has anyone found any Peach potato aphid in forward crops of rape this week?
Aphid monitoring sites have been showing steady increase in aphid catches recently (not surprising given the mild/hot weather).
I've only ever known neonic dressed raped (until this autumn) and don't know enough about the impact of Turnip Yellows virus... Are there any old timers or folk who regularly use undressed FSS with any experience of this disease?
With the astronomical cost of aphicide (Plenum, Teppiki, Biscaya etc) which controls the highly resistant Peach Potato Aphid the decision to spray is not an easy one!
