Abstract
Oilseed rape is an important break crop in Scottish arable rotations and
use of insecticidal seed treatments has been an integral component of crop
protection. A survey of 16% of the Scottish crop sown in 2014, the first winter rape
crops since EU restrictions on neonicotinoid insecticides were imposed, was
conducted. The survey found that more autumn insecticide sprays, almost
exclusively pyrethroids, were applied to crops than in the previous year. Some of
these additional sprays were precautionary. Whilst overall crop damage was rated
as low by the majority of growers, 1% of the crop area was redrilled due to autumn
cabbage stem flea beetle damage. A further 1% of the crop was redrilled due to
non-insect related issues. Average yield in 2015 was very similar to that reported in
2014. Recommendations for alternative crop protection strategies are presented.
