Growth rate on track and disease levels moderate

April 15, 2022, 9:52 a.m.

The latest crop update from Teagasc confirms that growth rates are about on track and disease levels are moderate.

Winter barley growth stages are near normal for this time of year. Most crops are at GS 31/32 after a period of slow growth over the past two weeks.

Fertilizer is up-to-date on most crops, but growth regulation and disease control have been delayed due to freezing cold nights.

Disease levels are low, but brown rust is present in some six-row varieties like Bazooka and Belfry. Cases of barley yellow dwarf virus (BYDV) have been reported, particularly along the southern coast.

Growth of winter wheat has slowed somewhat over the past two weeks due to some late frosts.

While many crops looked quite advanced a few weeks ago, they now look close to normal, which means that for most, the application of Leaf 3 fungicide will be expected towards the end of April.

Crop Update – Fertilizer

The main application of fertilizers is now due to crops as well as growth regulators.

Teagasc confirms that the oat crops still look quite ‘long’, although the internal growth stage is about normal for this time of year.

According to the crop watch chart, most are currently in growth stage (GS) 31. Crops for the next few weeks will need their final nitrogen breakdown as well as a growth regulator and fungicide.

Spring cereal planting is almost complete. Spring cereal acreage is expected to increase due to the tillage incentive scheme, with spring barley being the main beneficiary.

Establishment percentages are good in emergent crops due to good seedbed conditions following a timely dry spell in the second half of March.

The fight against pests, weeds and the spreading of fertilizers will be the priorities for the next few weeks.

Plant crops

Planting of the main crop is in full swing and, according to some growers, if the weather continues to be favorable over the next two weeks, many will be finished earlier than last year.

Ground temperatures are 1-2°C above normal and many parts of the country have received little rain since St. Patrick’s Day, so the ground is dry.

Finally the winter oilseed rape – the crops here are in full bloom at the moment.

Even crops with lower green zone indices (GAI) in early spring appear to have grown well over the past few weeks.

All nitrogen was applied except for growers using liquid forms of fertilizer. Disease levels appear to be low.
