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 �g/g seed) and triadimenol plus imazalil (225 + 75 �g/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.

Abstract A description is provided for Pyrenophora graminea. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Barley and other Hordeum spp. Also, occasionally, on oats, wheat and rye. DISEASE: Causes leaf stripe of barley. Severe seedling infection can cause stunting and post-emergence death, but symptoms are not usually apparent until later, when long, chlorotic or yellow stripes on leaves and sheaths appear. Most leaves of a diseased plant are usually affected. Dark brown streaks develop later in the stripes, which eventually dry out and cause leaf shedding. Ears may not emerge or be deformed and discoloured. Grain production by infected plants is severely restricted. GEOGRAPHICAL DISTRIBUTION: Widespread distribution; occurs in most barley-growing areas of the world. TRANSMISSION: Seed-borne (49, 1342) usually by mycelium in the pericarp. Perithecia are uncommon, but overwintering sclerotia on crop debris have been reported from Russia (42, 13). Secondary infection by conidia is apparently important only for floral infection and subsequent seed contamination.

Infection Experiments

A total of 19 Iranian native barley cultivars were in artificial infection experiments tested for resistance against isolate<br />19 of the leaf stripe fungs, Pyrenophora graminea. The cultivar Eram was immune against isolate 19 and the cultivars<br />Jonob, Makoy, C2, showed high resistance with less than 6% plant infected, the cultivars Zarjo, Valfajr, Reyhan, Karun,<br />Karun × Kavir were the most susceptible cultivars.
