3 Progress! Pesticide Use and Toxicity Down  Conventional pesticide sales down 3% per year between 1999 and 2006. (Crop Life, 2007)  Use of broad spectrum organophosphate and carbamate pesticides down. (California DPR) Miles to go…  94% of fish, 94% of surface water and 33% of ground water samples collected from 1992 and 2001 showed contamination with one or more pesticides. (2006 U.S. Geological Survey)  Herbicide-resistant weeds, invasive species, new drift regulations, non-target including pollinator impacts call for more IPM… Bald eagle nesting pairs increase from 417 to 5,748 after DDT ban. - Fish & Wildlife Service, 2003

4 IPM Reduces Pesticide Risk  IPM is an systems-based approach designed to reduce environmental, health and economic risks. IPM is implemented as an ongoing series of science-based, pest management evaluations, decisions and interventions.  IPM practitioners use knowledge of pest biology and environmental conditions, and technology to Prevent, Avoid Monitor and Suppress (PAMS) pests. Basic IPM Practices  Scouting (sampling) crops for pests and pest damage, visually or with devices.  Monitoring weather, other conditions.  Acting when pests approach economically damaging levels. Advanced IPM Practices  Resolve: Why is the pest there?  Pest-resistant crop varieties.  Crop rotation, adjust planting times.  Reduced-risk pesticides, mating disruption, companion crops, beneficial insects. Pest Scouting Pheromone Disruptor Suction Trap

5 IPM Opportunities through NRCS IPM Conservation Activity Plans (CAPs) provide an opportunity for Technical Service Providers (TSPs) and growers to work together to identify, prioritize and address resource concerns impacted by pests and pest management activities. Environmental Quality Incentives Program (EQIP) 595 Integrated Pest Management Standard offers cost-share rates and technical assistance for growers to implement IPM. Use NRCS Windows Pesticide Screening Tool (WinPST) to evaluate pesticide uses; mitigate if high risk. Conservation Stewardship Program provides cost-share rates and technical assistance for growers to implement conservation practices while maintaining practices already in place. Growers who practices IPM receive credit, increasing their chances of earning a CSP contract.

6  Funded by North Central IPM Center since 2006, with additional support from Northeastern IPM Center for IPM CAPs work in 2009-2010.  Expanding to national scope, merging with national IPM Conservation Activity Plan working group.  Over 100 members from NRCS, University Extension, crop advisors and others.  Goal: increase grower awareness and access to NRCS conservation programs for IPM, including CAPs, EQIP, CSP.  Activities include:  Create tools: IPM Tools, sample IPM CAP, IPM CAP training curriculum.  Recruit, train more IPM-qualified TSPs; acquire, share data on TSP payment rates with NRCS.  Provide mini-grants to North Central states for EQIP 595 enhancement.  Serve as a liaison between NRCS, IPM specialists and growers to support projects to increase state-wide adoption of IPM. Grower Incentives for IPM: North Central NRCS and IPM Working Group


8 Presentation Objectives  Give a Working Definition of IPM  Outline a few key pumpkin pests and related IPM control strategies  Translate IPM Practices into NRCS EQIP for Specialty Crop Guidelines  Conclusions

9 What is IPM?  The comprehensive and coordinated use of cultural, biological, and chemical tactics to reduce a pest population below an acceptable threshold  Cultural – non-chemical tactics, host plant resistance, planting date, cover crops, traps, scouting, crop rotation, sanitation, etc.  Biological – natural enemy conservation & enhancement  Chemical – pesticide selection and spray timing

10 Multiple Approaches to IPM  PAMS  Prevention, Avoidance, Monitoring, Suppression VS.  Seasonal  Pre plant, At plant, In season, Harvest, Post harvest VS.  Discipline  Weeds, Insects, Disease, Culture, etc.  Can couch IPM in various combinations or formats

11 Pre plant, At plant, In season IPM Insect & Disease Management  Key Pest(s): Striped cucumber beetle, may vector Bacterial wilt  (PP) Delay direct seeding until after 1 st generation of beetles decline  (PP) Use transplants  (AP) Use systemic insecticides in-furrow or seed treatments  (IS) Scout emerged seedlings, treat if cuke beetle threshold is exceeded

12 Bacterial wilt symptoms on pumpkin Striped cucumber beetles

13 Pre plant and In season IPM Insect & Disease Management  Key Pest(s): Aphids can vector viruses ZYMV, CMV, SqMV (WMV predominantly in OH)  Host plant resistance not commercially available  (PP) Plant early to avoid July / August aphid flights  (AP) Reflective mulch (not very effective)  (IS) Systemic or Contact insecticides will not control vector soon enough to prevent transmission

14 Aphid; Virus Fruit and Leaf Symptoms

15 In season and Post harvest IPM Insect Management  Key Pest: Squash vine borer  (IS) Use pheromone trap to detect adults end of June to mid July  (IS) Based on flight activity treat plant crown w/ insecticide  (PH) Destroy vines after harvest, kill SVB larvae & pupae

16 Squash Vine Borer Adult, Larva, & Trap

17 Pre plant and In season IPM Disease Management  Key Disease: Powdery mildew  (PP) Select PM tolerant hybrids when possible  (IS) Scout beginning mid July, treat as soon as PM colonies found  (IS) Rotate fungicide FRAC #’s to delay PM resistance  (PP thru IS) Keep updated on most effective fungicides, they do change over time

18 Powdery Mildew on leaf Powdery Mildew on handle

19 Pre plant - Post harvest IPM Weed Management  Key weeds: Pigweed, Marestail, Cocklebur Lambsquarters, Black nightshade, G. Ragweed, Velvetleaf, Grasses, others  (PP) Site selection and crop rotation, clean fields only  (PP) Stale seedbed  (AP) Use of Pre-emerge herbicides  (IS) Cultivate conventional fields until vines run  (IS) Post (spot spray) programs, hoe, hand pull  (PH) Reduced tillage combined w/ cover crops

30 Conclusions  Many approaches and tactics for Pest Management in pumpkin  Span from Pre plant to Post harvest (early to late season)  Insects dominate early, Diseases dominate late, Weeds are problematic throughout the season  Many opportunities for growers to use IPM AND protect SWAPA, & thereby qualify for conservation programs


32 NRCS/EQIP Program  NRCS will pay growers for up to 3 years to adopt practices that they think will improve conservation  Pest management is one of the practices they encourage  Recently, more interest in funding IPM for fruit and vegetable growers

33 EQIP for Fruit and Vegetables  Orchards  $90/acre  Up to $4500 per year  Vegetables  $45/acre  Up to $2250 per year

34 IPM in Apples  Must follow the IPM Elements developed by Ohio State  Points given for each practice  Total of 640 points possible  First do a baseline assessment of what you are already doing  Year 1: must have a score at least 10% higher than your baseline  Year 2: must have a score at least 10% higher than Year 1  Year 3: must have a score at 10 higher than Year 2 and be at least 60% of the total possible score (384 points)

35 How Do You Get Points?  Some points available for educational activities – Up to 45 points  Join grower organizations  Come to Extension meetings  Look at Extension websites  Buy Extension publications

42 Arthropod Management  If Oriental fruit moth is also present, use pheromone traps to monitor its activity, and adjust spray program as need to allow control of multiple generations. (15 points) Oriental Fruit MothCodling Moth

43 Arthropod Management  Use red ball traps to monitor for apple maggot flies, and use an insecticide to target maggot if thresholds exceeded. (5 points)  Monitor apple maggot fly with red-sphere attractants, and base control sprays on the threshold established for Ohio. (10 points)

44 Arthropod Management  Use pheromone traps to monitor adult populations of San Jose scale in blocks known for previous SJS damage. Base spray application timing for crawlers on detection with black sticky tape and/or on thresholds and/or degree day accumulations after catch of adults in traps. (5 points)

45 Arthropod Management  Survey European red mite populations on a weekly basis from petal fall until mid August using the Cornell mite sampling method and form. Apply miticide only if threshold exceeded. (10 points)

51 Arthropod Management  Select insecticides and miticides based on minimizing toxicity to predatory mites and beneficial insects. (10 points)

52 Arthropod Management  Rotate miticide product selection from year to year to avoid development of resistant populations. (10 points)

53 Arthropod Management  Spray a codling moth granulosis virus product to control codling moth.  Apply pheromone mating disruption products for CM and/or OFM.  Use a broadleaf ground cover in drive rows rather than a grass, to provide habitat for predatory mites.  Remove or destroy culled fruit.

54 Arthropod Management  Use trunk bands of corrugated cardboard to trap codling moth pupae; remove and destroy in June and post-harvest.  Use paper bags to enclose individual fruit to protect from pests.

55 Summary  Opportunities exist for some monetary incentives for improving your pest management practices  Meeting the qualifications probably will not be difficult for most growers  Conducting this self assessment allows you to compare your operation with that of others


57 A new, online pesticide evaluation tool for farmers, advisors, program managers, policy makers and others to fully evaluate pesticide options for impacts on health and the environment. Use Google Earth Imagery to map your field and identify sensitive-sites and mitigation zones. Automatically retrieve soils data from NRCS’s soils databases Create and save pesticide application records to generate site-specific risk ratings for human health, small mammals, birds, earthworms, fish and other aquatic organisms.
