Wheat Fungicide Facts

Click on the links below to find out more about the wheat timings and growth stages:

T0 Cleans-up the crop in specific situaltions to reduce pressure on the rest of the programme and provide more flexibility of T1 sprays
T1 Essential. Sets the crop up and maintains potential yield
T2 Essential. Keep the main yield-producing leaves free of disease
T3 Prevent the crop from late yield robbers and maintains grain quality

On average, T2 is the most important, followed by T1, then T3. In addition, T0 is a very sound extra investment at little cost in high early-risk situations.

T1 Wheat Timing / Growth Stage

T1 Essential. Sets the crop up and maintains potential yield

Peel back the leaves, or cut the stem lengthways with a sharp knife to expose the young ear. Now, the basal node is the one at the bottom, where the lowest leaves are attached. GS 31, termed first node detectable, is when there’s another node present, which is between the ear and the basal node. The distance between the basal node and this new node must be 1 cm or more – if it’s less than 1 cm, the plant is still at GS 30.

The plant is at GS 31 if an internode of 1 cm or more is present, and any internode above is less than 2 cm. As soon as that internode stretches beyond 2 cm then the plant is at GS 32, when there are two nodes detectable below the ear and above the basal node.

GS 33 is when there are three nodes detectable below the ear and above the basal node, and the internodes between node 1, node 2 and node 3 are greater than 2 cm.
