Effect of fungicide seed dressings on leaf stripe of barley caused by Pyrenophora graminea S. Ito Kuribay

Abstract

Eight fungicide seed dressings were evaluated in the southern cereal belt of Western Australia for control of barley leaf stripe caused by Pyrenophora graminea. Flutriafol (100 µg/g seed) and triadimenol plus imazalil (225 + 75 µg/g seed) were most effective. Control of leaf stripe with other fungicides depended on location. Imazalil appeared to be the ingredient most active against leaf stripe. Flutriafol and triadimenol plus imazalil offer effective control of leaf stripe and other endemic diseases (loose smut, powdery mildew, and scald) in the southern cereal belt.
