Chair of Laois IFA, Henry Burns says it could potentially happen if the Strait of Hormuz remains closed.
Farmers are warning the cost of food will rise if the Strait of Hormuz isn't re-opened soon.
Iran has effectively shut the vital route, causing fuel and fertiliser prices to surge in recent weeks.
About 30% of the world's fertiliser and 20% of the world's oil passes through the Strait.
Henry Burns, Chair of the Laois IFA, says rising fuel costs will also pose as a real threat:
