Cereal diseases

Wheat and barley starting to reach Growth Stage 30.

In the south of Ukraine we are seeing the earliest cereals reach the critical pseudo stem erect stage (GS30) with some individual plants moving in to GS31, ear at one centimetre.

Why is this crucial?

Two reasons, firstly you need to make sure all your nitrogen is on by this time and secondly it is the growth stage to start targeting T1 fungicide treatment if you are going to apply a T1.

T1 means first treatment and will be important this season because we are seeing a lot of septoria on the lower leaves, sufficient to represents a significant risk to justify a T1.
