Managing lands for both reduced wheat streak mosaic and benefits to wildlife and the environment (USDA)
These projects were supported by the North Central USDA-IPM Program and the Land Institute
Wheat streak mosaic virus, vectored by the wheat curl mite, produces trade-offs in management strategies.
An effective method of reducing disease risk in winter wheat systems is to remove the summer 'green bridge'
of volunteer wheat and weed hosts. But extensive use of tillage and herbicides in summer has a negative impact
on other ecosystem services, reducing soil conservation and removing food for economically important wildlife
(Cheatham et al., in review). Herbicide applications can be delayed until
later in the summer to maintain some of the benefits of plant cover. The timing of herbicides required to reduce epidemic
risk differs with the type of herbicide used (Jiang et al. 2005).
