Crops range from flag leaf emerging back to end of tillering for late-sown spring barley. Many crops have already received a first fungicide, some of which are targeting mildew while others are prophylactic. Spring barley still to be sprayed should get a triazole plus either a strobilurin or SDHI. Some varieties will also need a mildewicide. On a mildew-susceptible variety this should mean adding either Talius or Flexity with a morpholine to add persistence against mildew. Where there is only a little mildew on barley, Bontima could be used. All spray mixes should include two different actives to help against resistance.

Spring wheat and oat crops should have received growth regulator by now. If you don’t have mildew or rust then the first fungicide on wheat might be a triazole +/- morpholine +/- mildewicide plus a contact spray. This could be Tocata plus Bravo on wheat or Tocata or possibly Helix in oats.
