Joy Clarke, a Walsh Scholar PhD student at Teagasc Food Research Centre, Ashtown, discusses alternatives to chemical fungicides for controlling mushroom diseases. Diseases of crops are usually treated with chemical fungicides. Although their use is highly regulated and controlled, some of these fungicides can be toxic to the environment. They can also be harmful to our health. Some are no longer effective due to fungicide resistance and, because of this, are no longer approved for use. The Festival of Farming and Food is an educational, inspiring and fun week, packed full of amazing science activities, experiences, talks and exhibitions, for children and grown-ups alike. #FestFarmFood #ScienceWeek
