Certis’ insecticide InSyst has been granted emergency approval for the control of cabbage stem flea beetle in oilseed rape for a second year.

The Chemicals Regulation Directive (CRD) granted approval ahead of the OSR planting season. The decision comes after the NFU gained approval for two neonicotinoids subjected to a partial EU ban to be used over 30,000ha (an estimated 5 percent of England’s OSR area) this autumn.

InSyst contains neonicotinoid acetamiprid. The product has been granted a 120 day emergency authorisation for use before 25th November, at a maximum dose rate of 200g/ha and between growth stages BBCH 09 to 14.

Mike Hambly, combinable crops board chair with the NFU welcomed the approval on Tuesday; the NFU had complained that the CRD’s authorisation of Cruiser OSR and Modesto for use in four English counties this year would leave a large number of growers without protection. In the wake of July’s controversial ruling, the NFU said it would be actively encouraging regulators to accelerate approvals of other active ingredients.

This week, Certis’ product manager Inez Cornell said that as part of the emergency approval, Certis are asking growers to provide information, via a dedicated web-portal, to help provide a better map of cabbage stem flea beetle pressures across the country.

“By collating specific information in relation to pest pressures that are being seen first-hand, up and down the country, we can start to build a wider picture of the potential impact of this destructive pest,” she said
