A variety of crop seeds, in the sowing, emergence, growth, harvesting and storage process, often by a variety of pathogenic bacteria infection and damage, resulting in crops can not be normal fertility, affecting seed yield. Which carry the disease is more common with seed carrying, such as wheat tainted smut, millet grain smut, sorghum powder, Kennedy blacksmith and so on, mainly in the harvest after the mound, the disease panicle outer crush, Spread a lot of black powder, that is, the thick film spores of pathogens, attached to the surface of the seeds, the spring when the diseased seeds germinate in the soil, the spores grow invade mycelium, invasion
