For the second year in a row, Certis’ insecticide InSyst (acetamiprid) has been granted emergency approval for the control of cabbage stem flea beetle (Psylliodes chrysocephala) in oilseed rape.

CRD’s announcement comes ahead of the planting season for many, and is a welcome relief for growers across the country.

“There is a great deal of concern around the inability to control insect pests in oilseed rape crops, such as cabbage stem flea beetle. With the removal of certain seed treatments and active ingredients, farmers with high pest pressure saw crops overwhelmed last year before alternative products could be made available,” says Mike Hambly, NFU’s combinable crops board chairman.

“The emergency approval for the use of InSyst will help increase grower confidence in their decision to plant oilseed rape this year, where choices have not already been made, as well as help secure their ability to grow a successful, consistent crop.”

This 120-day emergency authorisation relates to the use of InSyst as an insecticide on winter oilseed rape for use at a maximum dose rate of 200g/ha between growth stages BBCH 09 to 14, for control of cabbage stem flea beetle, and application is to be made in a minimum water volume of 200 litres/ha.

Inez Cornell, Certis’ product manager explains 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.

“Having the emergency approval for InSyst is great news for growers this season. But it’s important we keep thinking of future options and are able to respond to grower demands and changing regulatory conditions,” she says.

Please note, growers are not permitted to use more than one autumn foliar application of any of the following insecticides actives; acetamiprid, clothianidin, imidacloprid, thiacloprid.

The 120-day emergency authorisation will expire on 25 November 2015.
