1. Cephalosporium stripe symptoms
Cephalosporium gramineum

2. Cephalosporium stripe
Very devastating in golden triangle 1960s to 1970s
1976 Choteau Co % yield loss
1993 near Great Falls 100% yield loss in a few fields
1991, est. 25 bu/a yield loss where winter wheat grown several successive years in MT
Produces soilborne conidia on residue in mid to late fall

3. Cephalosporium stripe
Soilborne
Only true vascular fungal pathogen of wheat
Favored by wet soil, fluctuating winter temperatures and repeated cropping of susceptible hosts
Soilborne conidia infect roots through wounds
Two phases
Seedling blight: mosaic, death, reduced stand and plants stunted
Near heading: one or two leaf stripes with darkened veins; darkened nodes

4. Cephalosporium stripe control
Late seeding to avoid large root system development
Also reduces damage by WSMV, root and crown rot, Hessian fly
Reduce nitrogen to prevent extensive root development
Minimum tillage to promote residue break down
Rotate out of winter grains for 3 yr
Plant legumes or spring grains
Survives in infected straw up to 2 yr
Liming of acidic soil to raise pH to 6.0 to 6.5
Elimination of grassy weeds

5. Cephalosporium stripe.
Winter wheat
Fluctuating temperatures (heaving)
Favored by continuous cereal crops
Control: rotation, plowing, varieties
