Farmers Weekly is again teaming up with Bayer CropScience for the Crop Doctor regional helicopter tour ahead of the most critical period in crop development.

We will be visiting four trial sites in Lincolnshire, Yorkshire, Herefordshire and Hampshire to assess disease risk and offer advice on fungicide programmes.

There will be two leading independent experts on board to answer your questions on septoria control and protecting crops against fusarium up to the T3 timing.

You can ask a question on our dedicated forum at www.fwi.co.uk/crop-doctor, via Twitter using the hash tag #cropdoctor or by emailing adam.clarke@rbi.co.uk.
