T3 time between the showers
June signals the time for T3 applications on winter wheat and while some farmers may have hit the fields already, others are waiting for timing and weather to come their way. Some may even be deciding whether or not to apply that final spray.
T3 applications provide plants with extra protection into the season and also protect the ear from diseases. For example, T3s may provide protection against fusarium.
In general, crops which have received strong T1 and T2 sprays are clean across the country, but septoria is visible on crops which have not received robust disease control programmes and rust is still causing problems for some farmers with susceptible varieties.
The T3 application, sometimes known as the head spray, should be applied to the ear of the plant, between GS51 and GS60, ideally at early flowering.
Prosaro, which contains both prothioconazole and tebuconazole, is a common product used on winter wheat and should be applied at 1L/ha.
Other options may include Gleam and Magnello. Growers should look out for mildew in crops and apply a mildewcide where needed.
