Kansas Phytopathological Notes: 1962

Planting Date and Variety Selection for Management of Viruses Transmitted by the Wheat Curl Mite (Acari: Eriophyidae)

“…Late-planted wheat was impacted more by spring inoculations because of limited fall growth and infection occurring prior to significant tillering early in the spring. In addition, Hansing et al (1950) observed that wheat planted early or late in the fall was significantly impacted compared with those seeded at the recommended planting date. These studies as well as data from the first two years of the current study indicate the importance of avoiding early planting.…”

“…It has been observed that early-planted wheat was more severely impacted by WSMV, whereas later-seeded wheat reduced the impact of WSMV (Willis 1984, Hansing et al 1950. Early seeding of winter wheat increases the potential for wheat curl mite establishment and virus infection, and early virus infection can lead to greater impact on wheat.…”

“…Hunger et al (1992) found that early and late-planted winter wheat could be significantly impacted by mechanical inoculation of WSMV. Lateplanted wheat inoculated in the spring was impacted more because of its limited growth stage, indicating that the maturity of plants at the time of infection may affect the impact of WSMV (Hansing et al 1950, Hunger et al 1992.…”
