Towards a No-Till No-Spray Future? Introduction to a Symposium on Nonchemical Weed Management for Reduced-Tillage Cropping Systems
Reduced-tillage systems including no-tillage and striptillage have well-known benefits for conserving and improving soils, protecting vulnerable crops from extreme weather events, and reducing labor and fuel costs associated with full-width inversion tillage. Despite these benefits, reduced-tillage has not been widely adopted in many cropping systems due in part to the increased difficulty of managing weeds when tillage is not used. Not surprisingly, adoption of reduced-tillage has occurred primarily in crops for which low-cost, effective herbicides are available, including glyphosate-resistant soybean [Glycine max (L.) Merr.], corn
(Zea mays L.), cotton (Gossypium hirsutum L.), and sugarbeets (Beta vulgaris L.). Increased use of a narrow range of herbicides in these cropping systems has exacerbated problems of herbicide resistance . Conversely,
adoption of reduced-tillage has been limited in crops where effective herbicides are not available (e.g. in ‘‘minor crops’’ like vegetables) or prohibited (e.g. in organic production systems).
