High Plains wheat mosaic emaravirus
Species of virus
High Plains wheat mosaic emaravirus (WMoV), or High Plains virus (HPV) or Maize red stripe virus (MRSV/MRStV) is the causative agent of High plains disease of maize and wheat.[1] It is spread by wheat curl mite, Aceria tosichella, which also transmits Wheat streak mosaic virus.[2][3] The mite's ability to transmit a number of different viruses to cereal crops make it an economically important agricultural pest.[4] In late June 2017 this virus was first detected in Canada, in Alberta.[5] The Alberta samples were 99% similar to those in the USA.[5] As Wheat streak mosaic virus is already present in Alberta, and coinfection with these two causes even more severe damage, this could cause much higher yield losses.[5]
