Adoption of chem fallow has been slow in the northern Plains, being used only on about 20% of the acres. It is one of the best practices to prevent wind erosion in the region. Roundup with 2,4-D and atrazine has been the standard treatment. Now Command is labelled for this use, and Command/atrazine is another choice. Carryover problems with atrazine can be avoided if rates are kept below 1/2 lb/ac.

This report summarizes six years of a field-scale integrated crop management experiment near Pullman, WA. The study focused on weed management intensity, residue levels for conservation compliance, and economic returns. Two crop rotations, two tillage systems, and three weed management levels were used. Plant diseases, insect pests, soil microbiota and earthworms were also monitored. The study will continue several more years. It took about four years for each treatment to stabilize, pointing out the need for long-term studies. Over time, the three year rotation with conservation tillage appeared most profitable and in compliance with residue levels. The low weed management level was seldom justified by weed control, yield, or profitability considerations. Moderate to high weed management were often the most profitable, although a reduction in the soil reserve of weed seeds with high management might allow periods of less intensive management in the future.
