The Toolshed- Publications and Information
These publications cover aspects of weed control from different perspectives. Ones known to be helpful for creating applied sustainable weed management systems are often annotated.
Bugg, Robert L., 'Cover crop biology: A mini-review.' Sustainable Agriculture, Part 1 in Vol. 7, Number 4, Fall 1995, pp. 15-17; Part 2 in Vol. 8, Number 1, Winter 1996, pp.16-18. Includes weed response results in a number of cover-crop experiments.
Buhler, Douglas, et al, 'Integrating Mechanical Weeding with Reduced Herbicide Use In Conservation Tillage Corn Production Systems.' Agronomy Journal, Vol. 87: 507-512 (1995).
______, 'Interrow Cultivation to Reduce Herbicide Use in Corn following Alfalfa without Tillage.' Agronomy Journal, Vol. 86:66-72 (1994). Three-year study showing yield increases from one and sometimes two cultivations independent of weed control impact. A third cultivation did not improve yield - and in some cases lowered yield - and was never profitable. Some studies have verified this 'cultivator effect,' while others have not. This study also showed that early season cultivation effectively reduced herbicide use.

Late planting is noted as maximizing weed control and minimizing weed/crop competition
