The aim of this trial is to evaluate the timing of insecticide treatments and the use of insecticide seed dressings on deterring aphids from feeding on newly sown wheat.
This trial has run for two years with no significant responses obtained, due to extremely low aphid numbers early in the season. It is hoped to continue this trial this coming season.
