Each season is quite different noticeably this one a little later than normal. Reading a 6 page “Agronomy Update” from a reputable source I was reminded of all the things predicted to go wrong with disease control in winter wheat. Rain events, timing of the T1 fungicide, active ingredients used, rate of product applied, varietal risk, drilling date and now the absolute necessity for eradicant activity from the T2 materials applied.
Much has been conveniently forgotten about the mode of activity of all chemical groups, where the timing of applications originally came from and what to do to remove the necessity of use for fungicides.
Now I read that reducing the rate of our new active ingredients is the way forward, in fact it will save you money. You should also remember the need for 3 Star drift reducing nozzles and a 12 m buffer zone for water courses unless the ditch is dry of course. Should you consider their use. All this seems a bit contradictory when considering the dire warning proffered earlier.
It may be wet, as these photos’ show, but well timed, the use of good chemistry can have a significant effect at keeping disease at bay, crops green for longer and consequently turning a noticeably different season into quite a profitable one.
