Timing matters when reducing fusarium head blight in barley

摘要

WHEN Fusarium head blight (FHB) threatens winter barley in the US, the best time to apply a fungicide is about six days after full barley head emergence, according to a recent study published in Plant Disease.FHB, also known as scab, is a fungal disease that attacks small grains, discolouring the heads and contaminating the grain with the mycotoxin deoxynivalenol (DON) - a toxic compound also known as vomitoxin.
