Kansas is on alert as Wheat Streak Mosaic Virus (WSMV) poses a severe threat to its wheat crops. The virus, known for causing significant damage, particularly in the western region, calls for immediate and collective action from the farming community.
In 2017, the state experienced a staggering loss of $76.8 million and 19.2 million bushels of wheat due to WSMV, highlighting the urgency of addressing this issue.
Conditions in recent years, including previous droughts and harvest challenges, have increased the risk of WSMV and related diseases. The presence of volunteer wheat, abandoned wheat, and unharvested weedy patches create a favorable environment for the virus to thrive.
The wheat curl mite, a carrier of WSMV and other diseases, survives on volunteer wheat and certain grasses. As these plants die, the mites seek new plants, spreading the virus. Early planted wheat is particularly susceptible and given that the mites can travel over a mile by wind, controlling volunteer wheat in the vicinity is crucial.
Farmers are encouraged to implement several preventive measures. Firstly, controlling volunteer wheat is a must. It must be completely dead and dry for two weeks before planting new crops. Avoiding early planting and choosing wheat varieties resistant to WSMV are also recommended, especially in the western parts of Kansas.
Resources such as the “Kansas Wheat Variety Guide 2023” provide valuable guidance for selecting the right varieties. Managing these diseases is challenging due to the lack of effective chemical options and the varying susceptibility of wheat varieties when multiple diseases are present.
The fight against WSMV is a collective effort. There are no shortcuts or easy solutions, but by working together and following best practices, Kansas farmers can protect their crops and mitigate the impact of this devastating disease.
