The new spray programme for 2021 must be strictly followed. There are a number of important changes to previous authorisations for this product, including:
InSyst can only be used in the second spray application slot.
- One spray programme: Teppeki
- Two spray programmes: Teppeki + InSyst
Only one spray of InSyst is permitted, rather than two sprays as per previous authorisations.
Remember the threshold: One green wingless aphid per four plants up to 12 leaves and increasing to one green wingless aphid per plant with 12 to 16 leaves.
- Growers are being encouraged to follow the weekly updates from the British Beet Research Organisation (BBRO) and regular website updates for aphid numbers and their virus content.
- The BBRO has more information on the emergency InSyst authorisation here.
