Bluetongue disease could arrive in Ireland before the summer is out, according to scientists at the Agri-Food and Biosciences Institute.

Last season, Barley Yellow Dwarf Virus (BYDV) posed a real challenge to both winter and spring sown cereals.
Barley Yellow Dwarf Virus (BYDV) is a key challenge for cereal growers, one that has both weather and geography-related themes.
Dr. Louise McNamara, has confirmed that all of the insecticides now available contain the same chemistries which impacts resistance
Early March-sown spring barley crops will not require an aphicide. However, those drilled later in the month will.
Tillage Technical
Despite the return of the rain and cooler conditions, a large area of winter cereals has been planted out in recent days.
Teagasc entomologist Dr. Louise McNamara is encouraging growers to check their crops for the presence of pests, including grain aphids.
Grain aphids can cause Barley Yellow Dwarf Virus (BYDV) related damage to a cereal crop within hours of arriving in it.
The challenges posed by aphids within a cereal rotation is a serious cause for concern for tillage farmers.
CAFRE is advising growers to be mindful of the impact that Barley Yellow Dwarf Virus (BYDV) can have on newly established cereal crops.

Natural plant defence mechanisms and traits, which could be bred back into cultivated wheat to protect against insects must be investigated
Teagasc’s Louise McNamara and Stephen Byrne have provided updates on the latest aphid monitoring work taking place in Ireland.
Early-sown crops of winter barley are at high risk when it comes to BYDV, along with crops planted along the coast.
Syngenta launched its BYDV Assist App for mobile devices. The device will help farmers and agronomists to make decisions on aphid control.
Looking at the results of the winter barley National List Trials, KWS Joyau stands out with a relative yield score of 121 in 2019.
The application of an aphicide to crops is an easy decision for some, but some tillage farmers are turning away from the use of insecticides.
BYDV can cause a loss of up to 3.7t/ha in winter barley. The virus also has the ability to affect wheat, oats and spring cereals.
In the past number of years BYDV - spread by aphids - has been an issue in spring barley crops. It can cause substantial yield losses.
Aphid numbers rose slightly into the new year, but are much lower than the same time last year. Teagasc carried out a count on January 2.
Aphid counts for the third week of November dropped to 7.6/m², from 4.1/m² the week before. These counts were taken in Teagasc Oak Park.
Aphid numbers have dropped back from their high at the end of October. Numbers at Teagasc reached 25.6 aphids/m² in the fourth week of October
Aphid numbers are low this October. Counts from unsprayed winter barley in Teagasc Oak Park have been ongoing since the start of the month.
AgriLand has learned that neonicotinoids will be available for use this autumn. Therefore the use of Redigo Deter will be permitted in 2018.
