Use

As a seed dressing, tebuconazole is effective against various smut and

bunt diseases of cereals such as Tilletia spp., Ustilago spp.,

and Urocystis spp., also against Septoria nodorum (seed-borne),

at 1-3 g/dt seed; and Sphacelotheca reiliana in maize,

at 7.5 g/dt seed. As a spray, tebuconazole controls numerous pathogens

in various crops including: rust species (Puccinia spp.) at 125-250 g/ha, powdery mildew (Erysiphe graminis) at 200-250 g/ha, scald (Rhynchosporium secalis) at 200-312 g/ha,

Septoria spp. at 200-250 g/ha, Pyrenophora spp. at 200-312 g/ha, Cochliobolus sativus at 150-200 g/ha, and head

scab (Fusarium spp.) at 188-250 g/ha,

in cereals; leaf spots (Mycosphaerella spp.) at 125-250 g/ha,

leaf rust (Puccinia arachidis) at 125 g/ha, and Sclerotium rolfsii

at 200-250 g/ha, in peanuts; black leaf streak (Mycosphaerella fijiensis)

at 100 g/ha, in bananas;
