Teppeki, an aphicide from Belchim Crop Protection, has been granted an emergency authorisation from the Chemicals regulation directorate (CRD) for the control of the Peach potato aphid (Myzus persicae ) in oilseed rape.
Since the ban on neonicotinoid seed treatments the threat of Turnip Yellows Virus (TuYV) has increased as the existing options available for control of the main vector ( M.persicae) are very limited.
A neonicotinoid foliar spray applied at the cotyledon crop stage for flea beetle control restricts the options even further as this timing is too early for aphid control and as only 1 neonic application is allowed in the autumn on OSR this rules out any subsequent spray for aphid control later on.
“As M. persicae are resistant to all pyrethroids there are now very few options remaining for aphid control and TuYV reduction in the crop so the addition of Teppeki to the armoury will be welcomed by both growers and agronomists,” says Simon Leak , Marketing and Development Manager for Belchim.
