*Scout to determine if treatment is needed

1) Review weed history and weed map/list.    
Use in choosing appropriate control strategies. 50% 10
Choose weed control strategies based on scouting information.

See the Weed Assessment List available for use in satisfying this element.
2) Crop rotation. Rotate with a small grain, field or sweet corn, or forage crop. Minimum three years away from vegetables or soybeans, longer depending on field history of root rot and white mold. 75% 10
3) Soil test every third year or prior to bean crop. Fertilize according to tests and crop requirements. Maintain records. 100% 5
4) Site specific soil sampling and application of lime and fertilizer. 1% 3
5) Calibrate sprayer before each growing season to ensure proper application rates and coverage. 100% 10
B. Planting    
1) Use certified western grown seed, preferably from an arid climate. 90% 10
2) Use seed treated with insecticide and fungicide for protection from seed maggots and diseases. 75% 5
4) Test use of available biological seed treatments. 1% 3
5) Calibrate seeder for seed size to obtain proper plant population. Conduct final stand count and compare to seed population. Evaluate causes of stand loss 2-3 weeks after planting. 25% 5
1) Scout for insects and diseases a minimum of two times per season. 75% 10
2) Rely on scouting and economic thresholds to determine treatment needs. 75% 10
4) Update weed map/list of the field when small for use in evaluating the current year's weed control and for use in determining if a post emergent treatment is needed. See the Weed Assessment List available for use in satisfying this element. 50% 5
5) Time post-emergent weed control according to crop stage, weed species, and size. 50% 5
6) Cultivate to control escaped weeds. 50% 5
7) Keep records of pest densities, root rot type and severity, biological control techniques used, cultural procedures, and pesticide use. 100% 5
8) When considering pest control, utilize methods that have the least impact on the environment and natural enemies. 25% 5
D) Post Harvest    
1) Make (or update if one has been made for this field previously) a weed map/list of the field for use in planning for next year. See the Weed Assessment List available for use in satisfying this element. 50% 10
2) To improve soil tilth and repair compaction either subsoil if conditions allow, or rotate with a sod crop. 20% 5
3) Till under crop residue to speed breakdown and reduce carryover of disease inoculum. 20% 5
4) Establish cover crop if possible, keeping field history of disease in mind when choosing cover crop. 10% 5
