The disease appears to be restricted to the Americas, where it can cause serious losses in mature ear weight (yield) and, in some cases, death of the plant. Under some conditions, epidemics of the disease may form. There are no satisfactory control measures for the disease, the pathogens which cause the disease, or the insect that transmits the pathogens. This chapter provides an up-to-date description of the biology of the disease complex. The information in this chapter will serve as a valuable reference for scientists and the extension service and will aid in the diagnosis of the disease. Technical Abstract: The corn stunt disease complex is considered to be caused by two or more of a complex of maize rayado fino virus, corn stunt spiroplasma, and maize bushy stunt phytoplasma, and is also known by the names achaparramiento, maize stunt, and red stunt, among others. This complex appears to be restricted to the Americas and can result in extensive yield losses of grain. The host range is primarily limited to members of the genus Zea, and the pathogens are primarily transmitted by the leafhopper vector Dalbulus maidis. Crop rotation and the planting of resistant cultivars may control the disease. |
