ABSTRACT
Most experts agree that future weed management systems will be more complicated. An integrated weed management strategy that combines physical, cultural, chemical and preventive weed control tactics would, among other factors, provide for a sustainable soybean production system. Most cultural weed control tactics in soybean husbandry such as cover crops, seeding rate or row spacing, competitive cultivars, or fertilization management can be included in integrated weed management strategies particularly when herbicides are less effective or herbicide use is excluded. Nevertheless, the multifaceted nature of weed management decision-making procedures, particularly nowadays with evolution and spread of herbicide resistant weeds, requires a judicious approach for an efficient weed control program to work. Some sets of management practices are complimentary, others are not, and hence any multi-tactical weed management approach should employ combinations of weed management practices that result in interactions that are synergistic or additive.
