April is the month when winter barley crops develop the quickest and the demand for plant vitamin is at its highest.
Relying on the whole quantity of nitrogen (N) for use, growers ought to guarantee that they apply the final cut up earlier than Development Stage (GS) 32, in line with recommendation from Teagasc.
Barley crops don’t use late N effectively. With a purpose to maximise yields, N have to be working earlier than the flag leaf is seen. Manganese deficiency can be fairly frequent in barley crops and desires consideration.
The place disease control is anxious, Teagasc is reporting that the choice to make use of a two or three-spray technique will rely on the variability and site.
Growers ought to use a three-spray programme on inclined varieties (e.g., cassia), or the place illness ranges are reasonable or excessive. That is particularly so particularly within the southern half of the nation.
Nonetheless, with crops within the northern half of the nation on clear varieties, growers might be able to get away with two purposes.
A steered spray plan follows: First spray – GS30; second spray – GS31 to 33; and third spray – GS39 to 49.
Fungicides that can be utilized embrace: Siltra at 0.6L/ha; Decoy copacks; Elatus Period at 0.8L/ha; MacFare Xpro or, Proline at 0.4L/ha plus a SDHI or strobilurin (Imtrex, Zulu, and so on.)
The place mildew is obvious, a mildewicide ought to be used. As well as, Folpet may be added to the final spray for the management of ramularia.
