How much nitrogen is in spring barley?

In spring barley this is likely to be nearer 130 kg N/ha. After ear emergence nitrogen uptake is very limited as nitrogen is redistributed to the developing grains. For spring barley then early rapid establishment is essential so at least 60% of the required nitrogen should be applied at planting.

Which fungicide can be used to treat black rot?

Mancozeb, and Ziram are all highly effective against black rot. Because these fungicides are strictly protectants, they must be applied before the fungus infects or enters the plant.
