After a topsy-turvy spring that’s compromised some early fungicide timing, adequately protecting the flag leaf at T2 has never been more important. CPM canvasses some advice. There’s lots of septoria in crops, not surprising given how wet it’s been. By Lucy de la Pasture This spring has created a bit of a catch twenty-two situation. The cold, wet winter and a similar start to spring may have reduced some early disease pressure but it’s also made travel difficult in many areas, compromising early spray timings. Cutting back early sprays unnecessarily risks allowing disease to establish and could put later applied chemistry under extra pressure, says Hutchinsons’ technical development director, Dr David Ellerton. The difficulty in the field is that in many situations the T0 had to be abandoned because, at the correct timing, the sprayer wasn’t able to travel. It’s a position Herefords agronomist and AICC member David Lines found himself in, with only 16ha of his planned T0 sprays actually applied due to the tricky weather. In his region most winter wheat crops have achieved plenty of biomass, he says, with only some of the later-drillled fields looking less than well tillered. “Most of my wheat…
