Emergency use of neonic seed treatment in sugar beet will not be triggered this year
It has been confirmed by the British Beet Research Association (BBRO), that the emergency use of neonic seed treatment in sugar beet will not be triggered this year.
The BBRO forecast on March 1, predicts that 8.37% of the national sugar beet area will be affected by virus yellows by the end of August 2021.
Under the terms of the emergency authorisation from the Health and Safety Executive (HSE) and Defra, this means that the use of Cruiser SB has not been triggered and will not be applied to seed this season.
Arrival of aphids
The forecast also predicts that the date of first aphids arriving in crops will be from May 18.
This is much later than when aphids were first recorded in crops in 2020 which was in late March.
This is a very similar national forecast to that in 2018. Aphids were first recorded in crops in late May 2018 and this is very welcome news for crops in 2021.
The BBRO also added that once seed is on-farm, drilling into good seed beds as soon as possible, will ensure crops establish quickly.
Consequently, plants will be more mature, resilient, and resistant to the impact of virus when aphids finally arrive.
The BBRO will monitor crops and will have a network of yellow water pan traps to assess aphid numbers during 2021.
