Chance to learn about SCEPTREplus trials on lettuce root aphid

0

Growers have had the chance to assess the latest set of field trials forming part of AHDB Horticulture’s SCEPTREplus trials, this time looking at the control of lettuce root aphid.

The aim of the trial is to determine the efficacy of novel treatments for the control of the pest on lettuce. According the AHDB, “In recent years lettuce root aphids have been managed effectively by the neonicotinoid seed treatments used to control aphids on the foliage. The impending loss of neonicotinoids will increase the risk of lettuce root aphid infestations.”

The trial, which consists of 12 treatments including the insecticide-free control and the commercial standard of Cruiser seed treatment, was visited by growers on 8 August. The experimental products have been applied as spray, drench or phytodrip treatments across two sequential plantings which have been timed to target the migration of lettuce root aphids from overwintering sites on poplar.
