The following practices are general guidelines that many, if not, most farmers in New Jersey already practice. It is felt that all farmers should be able to adopt these guidelines on 100% of their acreage within a 3-year period. It is recognized that adoption of specific practices may not always be possible depending upon the unique circumstances of the individual farmer. However, farmers should strive to adopt the highly recommended practices in order to be considered an IPM farmer.

A. SITE PREPARATION AND SELECTION

 Priority
H = high
M = medium
L = low

Ø      Review weed maps of fields to choose appropriate weed control strategies.

 H

Ø      Crop rotation. Rotate with small grains (wheat, barley) to avoid root rots and seed decay and reduce soil compaction.

 H

Ø      Soil test at least once every 3 years. Fertilize and lime according to test results. Assay a portion of soil sample for plant parasitic nematodes.

 H

Ø      Take soil sample from field to determine soil texture by mechanical analysis for each soil type within the field. This needs to be done only once for each field to help determine herbicide rates.

H

Ø      Take soil sample from field to determine percent organic matter to help adjust herbicide rates. This needs to be done whenever cropping practices change. That is, going from fallow to crops, from perennial crops to annual crops.

H

Ø      Rotate fields every year.

H

 B. PLANTING  

Ø      Use recommended commercial seed treatment and soil treatment for control of root rot, seed decay, and seed corn maggot.

H

 C. PEST MONITORING AND FORECASTING  

Ø      Update weed map of the field when crop small for use in evaluating the current year's weed control and for use in determining if a post emergent treatment is needed.

 H

 D. PEST MANAGEMENT  

Ø      Keep records of pest densities, pest favorable conditions, cultural procedures, and pesticide applications for use in the future, including incidence and severity of root and foliar diseases and seed corn maggot.

 H

Ø      Subscribe to Plant and Pest Advisory Newsletter - vegetable edition, or access via internet or by fax info-line and follow current, seasonal recommendations provided there.

H

Ø      Follow Rutgers Commercial Vegetable recommendations for pests that do not have thresholds

H

 E. POST HARVEST  

Ø      Make (or update if one has been made for this field previously) a weed map of the field for use in planning for next year.

H

Ø      Treat perennial weeds with nonselective translocated herbicides

H

Ø      Mow or disk fields after harvest to reduce pest populations.

H

Ø      Establish cover crop or plant another crop for weed control and nitrogen retention, root disease suppression, and reducing soil erosion.
