Growers and agronomists are flagging up dozens of cases of disease being found in wheat and oilseed rape crops right across the country.

High levels of septoria have been reported in wheat crops from East Lothian to Hampshire and Herefordshire to Northumberland, with certain varieties seen to be consistently fairing worse than others.

The levels of yellow rust in winter wheat is also cause for concern, with particular hotspots being highlighted in Norfolk, Suffolk, Nottinghamshire, Lincolnshire and the Midlands.

We have culminated a hefty list of tweets from growers and agronomists to form a general picture of the disease pressures lurking in crops this spring.

Hoping for a dry time between GS32 and flag leaf or this Septoria is going to be a problem #organicwheat pic.twitter.com/DuOmmHUirg

@olihillFW septoria is fairly bad in most varieties.It seems that early drilling this year was anything from September to end of October!
