Integrated Pest Management: Keeping the “I” in IPM J. P. Cuda, Ph.D.Entomology & Nematology DepartmentGainesville, FL 32611-0620
Instructor:Dr. Jim Cuda, Asst. Professor phone (352-392-1901 ext 126)email (jcuda@gnv.ifas.ufl.edu)Responsibilities: (Research 65%) Biological Control of Invasive Weeds (Extension 30%) Biocontrol of Insect Pests & Weeds
Agenda • Distribute Surveys • Background for New IPM Initiative • Principles and Practices of IPM
Surveys • MG Pest Management Practices • IFAS Accountability Survey
Why Are We Here ? • Homeowner reliance on pesticides is high and unsustainable • $$, Safety Issues, CWA, FQPA • Sarasota Co.- 26,000 lbs of pesticides collected in 1996 Amnesty Program • Federal mandate for viable pesticide alternatives • EPA prohibition of diazinon & dursban • Willingness of home gardeners to experiment
What is IPM ? • Applied pest control that combines and integrates biological and chemical control(Stern et al. 1959) • Manipulation of natural processes to increase their effectiveness; use pesticides only when natural processes fail to control pests (National academy of Sciences, 1996)
Goal of IPM ? • Avoid or prevent pest damage with minimum adverse effects on human health, non-target organisms and the environment • Emphasis on and integration of “sustainable” IPM tactics • Prevention, biological, cultural, mechanical controls, and reduced risk pesticides
Current Situation • Limited adoption of basic IPM principles : • Manipulate natural processes to increase effectiveness • Emphasis on ecologically- based tools instead of pesticides • Integration of compatible tactics • TECHNOLOGYTRANSFERFAILURE !!!
Problem Identification • Increase funding for interdisciplinary research and extension programs(IPM-SR, SARE grant programs) • Need for trained IPM practitioners (UF DPM program) • Improve public education about IPM and its benefits
What is Immediate Solution? • Establishment of IFAS Office of IPM and Advisory Committee • Dr. Norman C. Leppla, Coordinator • Identify IPM and biocontrol (BC) expertise in IFAS, DACS, and USDA • Inventory IPM successes in Florida • Increase visibility and delivery of IPM concepts and practices in county extension programs
Delivery of IPM Information and Technology Emphasizing Biological Control J. P. Cuda and N. C. LepplaEntomology & Nematology Dept.
Definitions • Integrated Pest Management (IPM) • Biologically-based pest control system • Combinations of control tactics to conserve natural enemies
Definitions • Biological Control, Biocontrol (BC) • Suppression of harmful organisms with natural enemies • Foundation of IPM programs
Goal • Develop State Major Program in IPM emphasizing BC • Establish a Design Team to assist in planning, implementing and evaluating SMP activities
Rationale for New SMP in IPM • County priorities • Florida FIRST imperatives • “Illusion of IPM” (Ehler & Bottrell 2000)
County Priorities (1999) • Increased demand for training and educational materials in IPM / BC • Priority program areas: • Agriculture, Horticulture, Natural Resources
Florida FIRST Imperatives • Water Quality & Management • Pest Protection • Food Technologies • Produce Society-Ready Graduates
“Illusion of IPM” • Limited implementation of “true” IPM • National commitment (1993) – 75% by year 2000 • Currently < 8% of U.S. crop acreage • Reliance on pesticides • Minimal integration of compatible tactics
Summit 2000 • Gainesville, 16 August • UF (state / county faculty) & USDA • Agronomy, Entomology, Horticulture, Nematology, Natural Resources, Plant Pathology • Commitments from FAMU, FLDEP and FLWMDs • Design Team Leaders selected • Norm Leppla, Jim Cuda and Gary Brinen
Accomplishments • Tentative Title for New SMP • “Delivery of IPM and Biological Control Information and Technology” • LIST- SERV and website developed • http://biocontrol.ifas.ufl.edu • Grant proposal submitted to SARE • Funding to support graduate student and distance education fees
Mission Statement • Provide leadership in developing educational materials and in-service training programs to support implementation of IPM emphasizing BC at local level
Design Team Functions • Build effective network of county, state and federal faculty committed to IPM emphasizing BC • Assist cooperating counties in identifying and developing demonstration projects
Design Team Functions (cont’d) • Facilitate acquisition and dissemination of information via IPM / BC web site • Develop / coordinate in-service training and distance education programs on the proper use of natural controls
Design Team Functions (cont’d) • Increase public awareness of BC and IPM by facilitating the documentation of IPM successes in appropriate media outlets
Achievable Goals • New partnerships • Extension Delivery System • Accountability
New Partnerships • Establish new IPM / BC partnerships • Coordinate efforts of BC scientists and county faculty • Link with private industry to develop practical BC agents and pesticide compatibility data
Extension Delivery System • Develop Florida IPM / BC website • Compartmentalized areas : • Teaching, Homeowners, Commercial, Issues • Commodities: Citrus, Ornamentals, Natural Areas, Turf, Vegetables, and Structural • Links to EDIS, DDIS, FAWN
Extension Delivery System(cont’d) • Increase training and implementation of IPM / BC at local level • New BC Facilities in Ft. Pierce and Davie • Training centers for BC agent biology, rearing and implementation • Establish & maintain demonstration projects • Develop & disseminate training materials
Accountability • Evaluation of SMP success: • Short term- • Informal / formal assessments • Monitor pesticide reduction at high use demonstration sites
Accountability (cont’d) • Evaluation of SMP success (cont’d): • Long term- • Incorporate IPM options into PM guides • Increase $$ for IPM research & education • Link IFAS, IPM program with Florida FIRST • Advance IPM and BC in Florida • General acceptance of IPM / BC
Principles of IPM • Avoid or prevent pest damage with minimum adverse effects on human health, the environment, and non-targets • Integrate most effective, compatible, and sustainable pest management tactics • Begin with “Prevention” & “Biocontrols” and extend to “Chemical” & “Physical”controls in ways that minimize environmental risks (Leppla 2001)
Components of IPM • Scouting • Process of finding suspected pest and identifying it • Use diagnostic labs &/or local resources (DDIS) to distinguish pests from beneficials • Maintaining records of pest occurrence • Establishing thresholds for plant damage • Determining if pest population is high enough to justify managing it • Using multiple tactics to manage pests • Prevention, biological, autocidal, cultural, chemical, and physical • Timing pest control measures to coincide with most susceptible developmental stage

Number of pests & level of damage beyond which treatment should be taken What are Thresholds? Pest EIL Natural Enemy NUMBER TIME
Economic Injury Level (EIL) • Pest population exceeds some threshold beyond which it interferes with plant health, appearance or profits
Aesthetic Threshold (AT) • Point at which thought or sight of pest population is nearing maximum human tolerance level
Why Use Thresholds? • Using thresholds can maintain or improve plant quality while reducing the amount and frequency of conventional pesticides
IPM Checklist (√) Prevention • Select healthy plants suited to habitat - Right plant, right place, right time • Inspect &/or quarantine nursery stock Biological control= Natural enemies • Predator- consumes more than one prey item during its development (e.g.,Lady beetle) • Parasitoid- lives in / on body of one host eventually killing it (e.g., Parasitic fly or wasp) • Entomopathogen- disease causing organism (e.g., Nematode, bacterium, fungus, protozoan, virus)
Kinds of Natural Enemies DPI DPI
IPM Checklist (√) Biological Control for Homeowners • Conservation- Maintain and enhance existing beneficial organisms • Alter control practices (e.g., timing of pesticides) • Provide nectar sources, additional hosts • Provide companion plants to attract and maintain beneficial organisms • Augmentation- Increasing numbers & kinds of beneficials • Inoculative-Acquire and release small numbers early in pest cycle • Inundative- Acquire and release large numbers to overwhelm pest
IPM Checklist (√) Cultural Control • Eliminate plant species that attract pests • Use pest resistant varieties • Remove and destroy heavily infested plants Physical Control • Using yellow sticky cards to monitor and/or trap insects • Use of screens, covers, barriers, and handpicking some insects
IPM Checklist (√) Chemical Control • Use selective (reduced risk) pesticides to preserve beneficials • Use microbial insecticides, e.g., Bts • Adjust application rates to protect beneficials • Spot treat areas when pests reach treatment threshold • Alternate pesticides to reduce resistance
Benefits of IPM • Reduced amount of pesticides needed to achieve control • Reduced environmental contamination from pesticides • Reduced risks of exposure to people, pets, and natural enemies • More economical • More effective long-term pest control
