activity against several diseases on many edible crops

and ornamental plants. Some diseases controlled or prevented

are rice blast, rusts, downy mildew, powdery mildew, late blight,

apple scab, and Septoria,

Ascomycota: Septoria; Deuteromycota: Pyricularia; Basidiomycota:

Stripe rust; Oomycota: Water mould ;including Wheat septoria,

Septoria leaf spot, Wheat leaf rust (Puccinia recondita),

Rye leafrust (Puccinia triticina),Powdery mildew, Downy mildew,

Stripe rust,Haustorium, Pyrenophora teres

Controlling spectrum
