Technical Abstract: Mechanical weed control is an option for supplementing or possibly replacing herbicide use in dry bean production. A series of experiments were initiated to examine the effectiveness of an in-row cultivator compared to a conventional cultivator and to identify the most effective timing of use. The in-row cultivator controlled more weeds than the standard cultivator when no herbicides were used. The highest level of control with the in-row cultivator (2 or 3 cultivations) was similar to chemical check. Effectiveness of the cultivator was due to the timing of cultivation in regards to weed emergence. In the second study, regardless of when the in-row cultivation was used, the addition of a rotary hoeing increased weed control. The in-row cultivator reduced the bean population in only one out of four trials. However, reduction in the bean population did not reduce yield. The cost of operating the in-row cultivator was similar to operating the standard cultivator. Therefore, the in-row cultivator is more efficient than the standard cultivators used in these studies. However, the in-row cultivator did require more adjustments and greater degree of driving skill than the standard cultivator.
