When the host plant is infected, lesions on the leaf start to appear as yellow discolored patches.

These patches will eventually turn brown and form characteristic V-shaped lesions in between the leaf veins.

[2] This pathogen can be easily cultured in potato dextrose agar at room temperature (20 -25 degree Celsius).

[3] Severe attack by Curvularia trifolii greatly reduces winter-spring pasture production of forageable clover and frequently coincides with feed shortage by late fall, leading to significant decreases in biomass production for overwintering clover species.

However, some growers choose to use fungicides instead of resistant hosts because this also prevents other fungal diseases from growing.
