.... In addition, 50 percent of the samples contained maize red stripe virus, more commonly known as High Plains virus. Both diseases are vectored by the wheat curl mite, Allen said. And so far, there's no treatment for either the viruses or the mite. The Great Plains Diagnostic Network is a part of a nation...
