IN VITRO EFFECTS OF FUNGICIDES AGAINST LEAF BLIGHT OF WHEAT CAUSED BY ALTERNARIA TRJTICINA

摘要

Leaf blight caused by Alternaria triticina is a major limiting factor in wheat growing regions of the country (1). The disease is particularly severe in introduced, rust resistant, high yielding dwarf Mexican cultivars (3). Losses of up to 100% have been reported (4). Fungicides have been evaluated for control of the pathogen by various workers (4) but. to date, no fungicide was found to be effective. The present communication report results of in vitro fungicide trials against A. iriticina.
