Desiccation - how to apply diquat alternatives to potato crops

Online event only

Get an in-field view of this year’s SPot Farm desiccation trials, as we continue to provide independent data on how best to replace diquat as a desiccant. We’ll provide observations form this year’s crop, look at completed trial results from previous seasons and an interview with lead trials researcher Mark Stalham, before an online Q&A.

There will be a review of previous webinar trials on desiccation from across the SPot network, and chance to look at mechanical options with video footage of four brands of mechanical flail.

This webinar will cover:

  • Trial results from chemical desiccation work at SPot farms
  • Video and of four mechanical flail options
  • Updates and observations from trial work on this year’s crops
  • Interview with researcher(s) and grower(s)
  • A live Q&A – questions can be submitted before or during the event
