May

What's happening in Wheat in May

Since the warm Easter weather, cereal crops have been racing through the growth stages. Most wheat received a T1 fungicide in the last two weeks of April prior to rain and flag leaves are expected to be fully emerged from mid-May onward.

With the high temperatures in late April and relatively little rain over recent weeks, things have dried out, but drought stress is far from being a concern yet. It does mean that disease levels in most crops are low heading into May.

Any rain will potentially increase disease pressure, especially from Septoria, so it is important to protect the top two leaves with a T2 fungicide, such as Ascra or Aviator, as keeping these disease free for as long as possible contributes to maximising yields. 

Later in the month, start considering ear sprays for protecting against Fusarium and other ear diseases.

Priorities this month (location dependent):

• Use cost effective T1 choices in late-drilled wheats
• Don’t be complacent against Septoria in drier conditions
• Use a robust T2 fungicide

April

What's happening in wheat in April

The dry winter means there has been plenty of residual nitrogen in the ground, and after rain in early March, winter cereals have picked that up and are looking fantastic.

Winter wheat crops are now moving rapidly and most are now at, or near, growth stage 30 leading into April. Even late-drilled crops are relatively forward due to the mild winter. Similarly, winter barley crops are growing quickly and reaching growth stage 30/31.

Early plant growth regulators are also now being applied to the most forward cereal crops. Classic dead heart symptoms, caused by wheat bulb fly, are appearing in wheat. Little can be done other than early nitrogen and rolling fields to help the crop thrive past the damage.

Although weather has been relatively dry through March, foliar diseases such as Septoria are present in winter wheat crops. If it turns wet during April, it could be a high disease year and applying a T0 fungicide will help suppress inoculum until the important T1 timing.

Some of the more forward wheats will reach the T1 fungicide timing later in April.

Priorities this month (location dependent):

• Consider protecting against eyespot at T1 fungicide timing in wheat
• Dissect main stems to get T1 wheat fungicide timing correct
• Monitor wheat disease risk in the field, not from the office

Priorities this month (location dependent):

• Complete grassweed herbicide programmes now to avoid workload and tank mix complications later on in the season
• Monitor crops for the development of foliar disease
• Assess weather conditions and consider a T0 fungicide later in the month if conditions allow

T2

Control Septoria and boost your wheat yields.

With 40% of yield contribution coming from the flag leaf getting the very best disease control at T2 can have significant upsides for your final yield. 

A T2 spray’s prime focus should be on controlling Septoria – the most widespread and biggest yield stealing disease in wheat, whilst also cleaning the top two leaves of any disease that may have developed since the T1 timing.

There are many options for T2 sprays available but even small percentage increases of control can have big impacts on final yields. Picking a trusted fungicide with proven performance will help you to get the very most from your crop and maximise your yield returns at harvest.

As part of our Judge for Yourself trials, 50 farmers tested AscraXpro against competitor treatments with a mean positive yield benefit of 0.3 t/ha.
