white and dark sided cutworms purple spot (Stemphyllium) annual broadleaves
asparagus aphids rust perennial grasses
    perennial broadleaves


A. Site Preparation Priority Points Acreage Goal Achieved
N 1) Select rust resistant and Fusarium tolerant variety (Jersey General, Jersey Giant, Jersey King, Jersey Knight) H 10 50%  
N 2) Avoid planting on sloped ground M 5 50%  
N 3) Select site with very well drained (sandy if possible) soil. H 10 100%  
N 4) Avoid history of crops susceptible to Fusarium        
- no asparagus, corn or sorghum for 8 + years H 10 50%  
- no asparagus for 8 years or corn/sorghum for 4   8    
N 5) Eliminate any perennial weeds. Identify weeds and select appropriate controls. H 10 100%  
N 6) Soil test and fertilize according to the test results. Adjust soil pH to 6.3-6.8. H 10 100%  
N 7) Utilize green or animal manure in year before planting to increase organic matter. M 5 100%  
B. Planting        
N 1) Use only crowns which are certified free of Fusarium. H 10 50%  
N 2) Plant to a depth of 8 inches on sandy soils; 4-6 inches on heavier soils. H 10 100%  
N 3) Use 30 pounds/acre P2O5 in bottom of furrow. M 5 50%  
N 4) Do not plant asparagus on ground needing nematicide treatment. H 10 100%  
N 5) Irrigate in year of establishment if needed M 5 100%  
C. Nutrient Management      

N,E 1) Soil test every 3 years H 10 50%  
N,E 2) Lime and apply potassium according to soil test. H 10 50%  
N,E 3) Maximum of 75 pounds of N per year post harvest. H 10 50%  
D. Pest Monitoring and Forecasting        
N,E 1) Scout several times a week for insects and foliar diseases during spear production (asparagus beetle, cutworms, slugs). Scout weekly during fern production (asparagus beetle, purple spot, rust) H 10 100%  
N,E 2) Use available thresholds for diseases and insects H 10 50%  
N,E 3) If serious disease is observed chop ferns after senescence and use shallow tillage to incorporate. If no disease observed then chop brush and do not till. H 10 50%  
N,E 4) Make a weed map/list annually and choose herbicide/tillage strategy according to weed species and populations. See the Weed Assessment List available for use in satisfying this element. H 10 100%  
N,E 5) Split the application of herbicide between pre and post harvest. M 5 25%  
N,E 6) For large fields(>5 acres) make use of border and hot spot sprays for asparagus beetle control. M 5 25%  
N,E 7) Chose effective labeled pesticides with the least environmental and beneficial organism impact (EIQ) H 10 50%  
N,E 8) Calibrate sprayer at least once per season H 10 100%  
N,E 9) Keep complete records of soil tests, fertilizer applications, cultural practices, weed maps, scouting results. and pesticide applications. H 10 100%  
E. Harvesting        
N 1) Do not harvest until the second or third year of crop depending on the vigor of the planting. (3 weeks of harvest year 2; 6 weeks year 3) H 10 100%  
N,E 2) Do not harvest spears less than 3/8 inch diameter. Remove small spears as needed to prevent overgrowth. H 10 50%
