Characteristics and Uses | 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; stem rot (Sclerotinia
sclerotiorum) at 250-375 g/ha, Alternaria spp. at 150-250 g/ha,
stem canker (Leptosphaeria maculans) at 250 g/ha, and Pyrenopeziza
brassicae at 125-250 g/ha, in oilseed rape; blister blight
(Exobasidium vexans) at 25 g/ha, in tea; Phakopsora pachyrhizi at
100-150 g/ha, in soya beans; Monilinia spp. at 12.5-18.8 g/100 l,
powdery mildew (Podosphaera leucotricha) at 10.0-12.5 g/100 l,
Sphaerotheca pannosa at 12.5-18.8 g/100 l, scab (Venturia spp.) at
7.5-10.0 g/100 l, white rot in apples (Botryosphaeria dothidea) at
25 g/100 l, in pome and stone fruit; powdery mildew (Uncinula
necator) at 100 g/ha, in grapevines; rust (Hemileia vastatrix) at
125-250 g/ha, berry spot disease (Cercospora coffeicola) at 188-250
g/ha, and American leaf disease (Mycena citricolor) at 125-188
g/ha, in coffee; white rot (Sclerotium cepivorum) at 250-375 g/ha,
and purple blotch (Alternaria porri) at 125-250 g/ha, in bulb
vegetables; leaf spot (Phaeoisariopsis griseola) at 250 g/ha, in
beans; early blight (Alternaria solani) at 150-200 g/ha, in
tomatoes and potatoes. |
