Wheat bunt

Infected plants have reduced height. The smutted wheat heads are bluish green when theyt emerge from the boot. The healthy heads are yellowish green. The disease also induces excessive tillering. The spores are blown by wind to developing ears which they invade. Bunt infected flowers have green ovaries while healthy ones are white. The grain of wheat is replaced by a black mass of spores (spore ball) accompanied by a smell like of rotting fish.
