Met Éireann has today (Friday, August 4) issued a potato blight advisory for the entire country for the coming days.
The national forecaster said that the southwest, west and north will be particularly at risk.
The advisory, which is now in effect, is currently due to remain in place until 1:00a.m on Wednesday (August 9).
Conditions for spraying will be moderate to poor over the coming days with some spells of wet weather, accompanied by blustery winds at times.
The best opportunities will arise between the showers on Friday and Sunday.
Potato blight is a disease caused by a fungal-like organism called Phytophthora infestans.
The disease spreads rapidly in humid weather in the foliage of potatoes and tomatoes, causing the foliage to decay and the potato to be infected.
According to Teagasc, around €5 million is spent by potato growers on fungicides annually in Ireland to mitigate the impacts of blight.
