Supported by the HTA, Bayer, ICL, Fargro and BASF alongside the event's official media partner, Horticulture Week, the industry summit is not to be missed by those keen to have their say in developing a preventative strategy for vine weevil control.

"The membership of the HTA has struggled again over a number of years now, to achieve effective control of vine weevil with loss of actives to the market," says John Adlam, crop consultant and council member at the HTA.

"In a bid to set down an industry strategy to address the issue, the HTA, along with Bayer and ICL, instigated the summit that will bring together the whole spectrum of the industry affected by vine weevil, to discuss effective methods of control that are available now.

"We need to get a collaborative approach to the problem from researchers, supply companies, growers and retailers. The summit will bring these groups together to speak about the pressures they face so that all sides understand the problems encountered by each other," says John.

Andrew Wilson is technical manager at ICL and distributes the insecticide Exemptor from Bayer for the control of vine weevil, incorporated into growing media. He believes that the summit is urgently needed. "Clearly IPM already plays a role but with the crop protection armoury diminishing, we need to find an industry solution to retain access to effective controls and promote responsible use, best practice and, agree on a total integrated approach to pest management."

John Adlam is seeking an industry-led protocol to come out of the summit that covers all crop situations where vine weevil control has proven to be a problem in the past. "Ultimately the summit will end with an industry solution and anyone who wants their say should not miss it."

The event which will take place near Banbury from 10am until 3pm, features an impressive line-up of speakers, including:

  • John Adlam representing the HTA
  • Jude Bennison, ADAS
  • Wayne Brough, AHDB
  • Marcus Cousins, Aylett Nurseries
  • John Richards, John Richards Nurseries
  • Alastair Hazell, Darby Nursery Stock
  • Dr. David Chandler, Warwick University
  • Dr. Colin Mumford, Bayer
  • Andrew Wilson, ICL
  • Dr. Paul Sopp, Fargro
  • Jorge Tirado, BASF

The summit will establish the true extent of the problem faced by the industry, delve into understanding the pest, the current controls available and will culminate in an a lively debate, chaired by Kate Lowe, editor of Horticulture Week, to produce some concrete next steps for the industry to take to combat the pest threat.

The session is set to conclude with an insight into research and future developments from Dr. Dave Chandler of Warwick University, speaking on the future of vine weevil control.
