Its been known for years that the Downey Mildew Fungus can cause Crazy top in corn but what has not been observed very often is the same crazy top disorder in wheat.Infection can only occur when plants are covered in water and their leaves are scarified by abrasive soil particles.The scarified leaf surface acts as a portal of entry for the mildew fungus.Once inside the plant it disrupts the reproductive system in a manner that causes it to produce a multiproliferate of leaves rather than grain.There is no worry of spread as the only way the fungus can cause this reproductive disorder is when soil and water cover over the entire plant at an early stage of development.
