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.

T0 Wheat Timing / Growth Stage

GS 20 describes tillering: the number after the 2 represents the number of tillers. So GS 23 would describe main shoot, plus three tillers; GS 25 is main shoot, plus five tillers. From any number of tillers, the plant can then move straight to GS 30, which is termed ear at 1 cm, or early stem extension.

Check crops either by carefully peeling back the leaves to reveal the ear stump, or by cutting through the stem with a sharp knife to expose the ear.

Measure the distance between the top of the ear and the basal node where the lowest leaves are attached; GS 30 is when this distance is 1 cm or more.
