Scientists have found diamondback moth (DBM) caterpillars surviving in UK Brassica crops this winter and are recommending growers check their own crops for the pest now.
Previously considered a migratory pest, recent research from AHDB indicated that diamondback moths could be surviving UK winters.
AHDB’s Dawn Teverson, and Rosemary Collier from Warwick Crop Centre have been out in the field hunting for the caterpillars and found the pest on the underside of leaves in un-netted swede crops, located in the south west of England.
Scientists at the John Innes Centre (JIC) are developing a new line of fast-growing sprouting broccoli that goes from seed to harvest in 8–10 weeks. It has the potential to deliver two full crops a season in-field or it can be grown all year round in protected conditions, which could help with continuity of supply, as growers would no longer be reliant on seasonal weather conditions.
