This year has been declared the International Year of Plant Health by the United Nations General Assembly, the idea is to raise awareness on how protecting plant health can help end hunger, reduce poverty, protect the environment, and boost economic development. In this issue of Quest we show some ways in which scientific research is helping to protect plants from pests and diseases, manage the risks and mitigate the impacts.
