OSR flea beetle damage down in second season without neonicotinoids

About 1 per cent of the UK’s winter OSR crop was lost to flea beetle damage in the autumn, significantly down on 2014. But the figures do not undermine the case to retain neonicotinoids, say industry experts.
About 6,000 hectares of winter oilseed rape (WOSR) was lost as a result of adult cabbage stem flea beetle activity across the UK in autumn 2015, according to a survey by AHDB Cereals and Oilseeds.
In the second planting season without access to neonicotinoid pesticides for most growers, the estimated losses amounted to about 1 per cent of the WOSR crop, down from 2.7 per cent in 2014, albeit with a different methodology deployed by AHDB.
