Emergency approval granted for InSyst

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

CRDs announcement comes ahead of the planting season for many, andis a welcome relief for growers across the country.

There is a great deal of concern aroundthe inability to control insect pests in oilseed rape crops, such as cabbagestem flea beetle.  With the removal of certain seed treatments and activeingredients, farmers with high pest pressure saw crops overwhelmed last yearbefore alternative products could be made available, says Mike Hambly, NFUscombinable crops board chairman.

The emergency approval for the use ofInSyst will help increase grower confidence in their decision to plant oilseedrape this year, where choices have not already been made, as well as helpsecure their ability to grow a successful, consistent crop.

This 120-day emergency authorisation relates to the use of InSystas an insecticide on winter oilseed rape for use at a maximum dose rate of200g/ha between growth stages BBCH 09 to 14, for control of cabbage stem fleabeetle, and application is to be made in a minimum water volume of 200litres/ha.

Inez Cornell, Certis product manager explains that as part of theemergency approval, Certis are asking growers to provide information, via a dedicatedweb-portal, to help provide a better map of cabbage stem flea beetle pressuresacross the country. By collating specific information in relation to pestpressures that are being seen first-hand, up and down the country, we can startto build a wider picture of the potential impact of this destructive pest.

Having the emergency approval for InSyst is great news for growersthis season. But its important we keep thinking of future options and are ableto respond to grower demands and changing regulatory conditions, she says.

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

The 120-day emergency authorisation will expire on 25 November2015.
