Teagasc Spring Crop Walks 2025
The series of Teagasc Spring crops walks are already underway due to the early drilling season, topics at the walks include;
- spring cereal crop management,
- winter cereal crop management,
- adjusting disease control programmes,
- weed resistance
20 IASIS points have been awarded for each event.
Details of all the events can be found on the Teagasc website.
Glyphosate Resistance
Teagasc have confirmed the first reported case of a field population of the grass weed Italian ryegrass, that has proven resistant to glyphosate.

Winter Wheat
Crops have progressed well over the last few weeks with most crops having had their main split of nitrogen applied a few weeks ago. Most crops are up to date with PGR and many received a leaf 4 fungicide to protect against septoria and rust.

Winter Barley
Winter barley growth stages range from GS32 to awn emergence in some early maturing varieties that were sown early. However the majority of crops are between second last leaf emerged to flag leaf emergence. This is the ideal time for final PGR if it is required. Disease levels are very low and ramularia will be the target for the final fungicide timing at awn emergence.

Spring Cereals
Spring 2025 has been excellent, with all spring cereals planted before tillage farmers had even started planting last year. Establishment is excellent due to favourable seedbed conditions at sowing although moisture will be welcome to help growth and to alleviate crop stress on light soils. Growth stages range from emergence to early tillering in early sown crops. Nitrogen application and weed control will be the priority in the coming days.

Winter Oats
Winter oat crops are generally at GS 32 at the moment which is the key timing for growth regulation. Crops are generally claen and most have receib=ved all their nitrogen at this stage.

Winter Rye
Crops have become quite tall as normal over the last couple of weeks, with many now approaching flag leaf stage and so they will soon need their final growth regulator application. Some early sown crops in the south have reported that heads are starting to emerge. There are no reports of any disease on crops given the dry weather.

Fodder Beet
A good proportion of this year fodder beet crop is in the ground but some still remains to be sown as growers await kinder conditions for emergence. The loss of Triflusulfuronmethyl (Debut) makes weed control more difficult especially where brassica weeds are present. Pre-emergence applications of Metamitron (Goltix) or Ethofumesate (Nortron) can add some flexibility to timings but good soil moisture is essential for good performance.

Potatoes
Planting of maincrop varieties is coming to an end in most areas, conditions for planting has been ideal over the last three weeks or so. Early planted crop will soon start to emerge and will require a pre emergence herbicide in the coming weeks.
