Non Technical Summary
Consumer concerns about pesticides and food safety are growing and placing increased pressure on land grant Universities to provide growers with effective management strategies that minimize the impact of pesticides and fertilizers on food products and the environment. Highly visible cases of food-borne illness, such as Salmonella contamination in peanuts and poultry, E.coli contamination in lettuce, as well as increasing rates of cancer globally are drawing more attention to food safety and management at the farm level. The shift toward organic production and consumption is increasing the need for alternative control methods that are of low risk to health and the environment. Meanwhile, producers require cost effective management strategies in order to remain viable in the agriculture industry. The University of Georgia IPM program and collaborative efforts among UGA and other institutions have created an atmosphere conducive to programs which not only benefit the state of Georgia but the entire southern region. Specific, targeted pesticide applications and implementation of alternative management strategies (e.g. planting of resistant cultivars, use of Bt cotton) have reduced the overall number of pesticide applications and amount of active ingredients applied to agricultural crops. Currently, integrated management teams are developing and constantly refining IPM programs in many critical sectors of agriculture throughout the state of Georgia. Teams of IPM experts, including entomologists, plant pathologists, agronomists, weed scientists, and others, are currently at the forefront of pest management research and extension efforts in cotton, peanuts, fruits, vegetables, and poultry production. Coordination among these efforts provides efficient transfer of data from researchers and extension specialists to extension agents and grower groups. In addition, open communication links from specialists to stakeholders promotes input from stakeholders, outlining problems and concerns to be addressed by specialists. This two-way avenue of communication is critical to the success of any IPM program. Flexibility and adaptability of Georgia's IPM programs allow them to remain relevant and adequately serve stakeholders. It is expected that the outcomes/impacts of this program will result in changes in knowledge concerning the biology of new and emerging pest problems. Further, changes in action are expected as new and innovative pest management strategies are developed and tested by extension experts. Lastly, changes in environment due to higher agricultural productivity, improved animal health and production, a safer food supply, and a cleaner environement are expected from the work proposed here.

Goals / Objectives
Goal of the Georgia IPM Program: The goal of the Georgia IPM program is to utilize a science-based decision making process to increase the implementation of IPM practices in Georgia agriculture in order to minimize environmental and economic risks from pests and pest management strategies. The objectives designed to meet this goal are: 1) development of integrated pest management plans through specialized research and innovation and 2) effective communication with growers, commodity groups, and regional and national IPM centers. Management practices are focused on reducing human health and environmental risks associated with pest management, and improving the cost benefit of IPM practices for producers. Specifically, the IPM program works to develop new pest management strategies, provide education to both public and private entities, and to promote implementation and adoption of these practices through extension. Emphasis areas include IPM Implementation for Agronomic Crops (peanuts and cotton), IPM Implementation for Animal Agriculture (poultry), IPM Implementation for Specialty Crops (peaches, vegetables and blueberries), and IPM Support for Pest Diagnostic Facilities. Emphasis areas are focused on high value and high impact crops for the state of Georgia.
Project Methods
Currently, integrated management teams are developing and constantly refining IPM programs in many critical sectors of agriculture throughout the state of Georgia. Teams of IPM experts, including entomologists, plant pathologists, agronomists, weed scientists, and others, are currently at the forefront of pest management research and extension efforts in cotton, peanuts, fruits, vegetables, and poultry production. Stakeholders are engaged in setting extension IPM program direction through several, intentional processes. Input and feedback is collected from growers, crop consultants and pest control operators during workshops and conferences. Current grower issues are often communicated by research funding opportunities through commodity groups such as the Georgia Fruit and Vegetable Growers Association, Georgia Peach Council, Georgia Peanut Commission, Georgia Pecan Commission, Georgia Pest Control Association, and the Georgia Cotton Council, which direct research efforts toward current and emerging pest problems. The Extension Leadership System (ELS) in Georgia is a statewide network of stakeholders and county-based volunteers working to support, and advocate for, Extension programming at all levels. In each county one or more Program Development Teams (PDT) are active by Extension program area, including 4-H Youth Development, Family and Consumer Sciences, and Agriculture and Natural Resources. In addition to the PDT's, an overall county council serves to coordinate efforts for advocacy and support of the total local Cooperative Extension program. The Extension Leadership System is designed to help focus the resources of the University of Georgia on a county's most critical needs and opportunities for improvement and refinement of IPM programs. PDT's provide guidance, assistance, and leadership for designated program areas. The program will be evaluated with both direct and indirect methods. Yearly reports will be produced outlining research efforts and highlighting changes and refinements to existing management recommendations. Measurements of pest levels, crop or animal yields, can pest control costs will be used to examine the effectivemess of the IPM program. Measurements of stakeholder contact through commodity meetings, field days, and IPM documents will be used to help determine reach and impact of extension activities.

Outputs
Target Audience: The efforts of the Georgia Integrated Pest Management program are primarily targeted at agircultural producers of agronomic, high input, and high value crops within the state of Georgia. These include cotton, peanut, blueberry, peach, vegetable, and poultry producers. In addition to this primary group, the IPM program is making efforts to extend expertise and assistance to small scale farmers and organic producers. Changes/Problems: Nothing Reported What opportunities for training and professional development has the project provided? Peanut IPM- Peanut team members participated in 7 field days, and conducted over 50 county ormulti-county education programs, and the yearly tri-state Peanut Diseases tour with Alabama and Florida. Cotton team members haveconducted over 72 county or multi-county training events reaching over 3000 individuals, and have held 13 field day events .Brown Rot Management in Peaches- Effectivedemonstration of the Profile Resistance monitoring kit was continued for peach growers of Georgia and South Carolina. In aneffort to transfer this fungicide resistance monitoring technique to a stand-alone program, project personnel have advertised togrowers information for maintaining resistance monitoring.Vegetable IPM- Vegetable teammembers conducted 39 county or multi-county extension training events with an average attendance of 30-50 people. Teammembers held 12 field day events reaching 500+ individuals, and served as organizers for the Southeast Regional Fruit andVegetable conference. Diagnostics- The bugwoodnetwork received435 million web hits (50 million unique visitors). Currently, the EDDMaps program, maintained by the center, ismonitoring the spread of invasive species throughout the US. The notable examples are the recently introduced plataspid bugMegacopta cribraria in GA, SC, AL, TN, and NC, expanding boa constrictor populations in FL, and spotted wing drosophila in the eastern United States. This tool can be used fordecision making at local, state, and regional levels. How have the results been disseminated to communities of interest? The results were communicated with Georgia crop producers, extension personnel, and pest management professional via presentations at growers and professional meetings, field days, research and extension publications (The details are provided in products and accomplishments sections). What do you plan to do during the next reporting period to accomplish the goals? Nothing Reported

Impacts
What was accomplished under these goals? 1) Development of integrated pest management plans through specialized research and innovation: Georgia Cotton IPM celabrated the 25th year anniversary of the eradication of the boll weevil. Recent research and extension efforts by the cotton IPM team have led to significant increase in utilization of Bt transgenic varieties which has resulted in dramatic reduction in insecticide usage in cotton. Cotton growers have gone from 15-16 applications per season to an average of 1.6 applications over the last couple of years. Stinkbugs and thrips are now the most common pests of cotton in Georgia. Georgia cotton IPM team has successfully developed IPM programs to effectively manage stinkbugs using reduced-risk tactics. Cultural control strtageis based on selection of planting date to help cotton growers minimize the risk of thrips infestations. Georgia Peanut IPM programs focused on developing management programs for soil borne diseases such as white mold.From research conducted in recent year at the University of Georgia, it is evident that an early start to the management of soilborne diseaseslike white mold can have a real impact on the efficacy of the fungicide program.Whether through use of Proline within weeks after emergence or early-season use of atebuconazole tank-mixed with a fungicide for leaf spot, these treatments often benefitand supplement the control of white mold provided by our standard programs beginning60 days after planting. Implementation of these strategies has helped growers increase their profitability significantly.Tomato spotted wilt virus (TSWV) is another major problem in peanuts that both entomologists and plant pathologists have worked together to address. The use of peanut disease risk index "Peanut Rx" and resistant varieties have significantly reduced peanut crop losses due to tomato spotted wilt virus.Our efforts to implement IPM programs in and around poultry farms focused primarily on managing darkling beetle populations which have emerged as the major pest in broiler production worldwide. Research and extension efforts helped evaluate and implement new management technologies to manage darkling beetles. A project was also conducted to assess the rsik of insecticde resistance in darkling beetle populations throughout the state of Georgia and help poultry farmers develop resistance management programs. The most important specialty crops in Georgia include peaches, vegetables and blueberries. Fungicide resistance was one of the major problems and the peach IPM program in GA and SC collaboratively developed fungicide resistance monitoring program for peaches which is estimated to have saved peach producers approximately $20 million in damages and wasted fungicide applications. A pilot project was conducted to demonstrate effectiveness of IPM programs in order to facilitate re-acquisition of export opportunities to Mexico. The project was successful and resulted in a shipment of 20 loads pf peach with an average of $4 per box premium which earned over $121,000 during 2011, the first year of this project. The economic returns for US peach growers through exports have increased since 2011. Blueberries have grown to be a major commodity in Georgia and blueberry growers have never faced pest problems until 2011 when spotted wing drosophila was first detected in Georgia blueberries. Initially several growers lost their entire crop to SWD, however, Georgia blueberry IPM program launched aggressive extension efforts to educate growers and extension personnel about this devastating pest and help them implement management programs. It saved growers millions of dollars in crop losses. Georgia vegetable IPM prgram focusedon developing sustainable management strategies for whiteflies and diamond back moth. Whiteflies cause serious economic losses to several of Georgia's key vegetable crops including to tomato, squash, melons, pumpkin, cucumber, snap beans, cabbage, collards and others. The most severe loss occurs when both whiteflies and the Begomoviruses they transmit attack the same crop. Research conducted by our vegetable IPM team membres has led to development of effective chemical and cultural practices to manage whiteflies. Additionally, tomato host plant resistance to Tomato yellow leaf curl virus (TYLCV) has also been demonstrated as an effective alternative strategy. Thse studies have demonstrated that all these strategies implemented as part of an IPM program could significantly reduce yield losses due to whiteflies and TYLCV.Being high value crops, vegetables are frequently sprayed with insecticides to control insect pests which increases the risk of resistance development in major pests. Studies were conducted to determine susceptibility of diamond back moth to existing and new chemicals and develop resistance management programs. The results demonstrated that pests have not yet developed resistance to newer chemicals such as diamides and that resistamnce management techniques of insecticide rotations are cost effective in Georgia growing conditions. IPM Support for Pest Diagnostic Facilities - Georgia IPM program maintains disease diagnostic labs in Athens and Tifton, and offer insect disgnotic services in Athens and Griffin. Disease and pest samples are submitted via DDDI systems by clientele across the state and our diagnosticians help identify the problem and report back in as short as one day in most cases. User feedback indicates that DDDI has saved Georgia citizens more than $11 million and helped save the life of a child that ingested a poisonous plant. Every county in the state of Georgia has ready access to DDDI, and DDDI systems have been developed for Extension Service organizations in ten other states (http://www.dddi.org). Additionally, our bugwood network hosts over 124,539 imagesof insects, plants, plant diseases, and weeds. Growers, homeowners, and extension agents can use the images in Bugwood to identify unknown insect and pathogen pests and bring this to the attention of extension specialists. The images are free to users around the world for Extension and educational purposes. Since 2002, the database has reported 435 million web hits (50 million unique visitors). 2)Effective communication with growers, commodity groups, and regional and national IPM centers: The Georgia Pest Management Handbook (Commercial and Homeowners edition) is the most important and high impact publication produced annually and is utilized by growers, extension personnel, and pest management professionals to implement IPM programs. There are a number of ther newsletters such as Georgia Cotton PestManagement Newsletter which were used to communicate with growers across the state. A mentioned in detail in products section, all Georgia IPM Team members made presentations locally at the grower meetings, conducted field days, and published research and extension articles to communicate their finding with crop producers and other tskaeholders. Presentations were also made at the professional meetings at regional, national, and internatinal level. The cotton team has produced several issuesof the Cotton Pest Management newsletter and the Cotton Growers Newsletter. Cotton team members havemaintained the Cotton Insect Hotline (1-800-851-2847)which provides up to date management information for cotton insect pests

PROJECT MODIFICATIONS: Nothing significant to report during this reporting period.

Impacts
The fungicide resistance monitoring program for Peaches in SC and GA is estimated to have saved peach producers approximately $20 million in damages and wasted fungicide applications. Georgia Cotton IPM is celebrating the 25 year anniversary of the eradication of the boll weevil. Elimination of this pest and utilization of Bt transgenic varieties has resulted in a dramatic reduction in insecticide usage in cotton. Growers have gone from 15-16 applications per season to an average of 1.6 applications over the last 5 years. Surveys collected from vegetable field days have indicated a 36% increase in knowledge for participants. Of those surveyed, 1% indicated that they intended to implement new IPM strategies into their production practices as a result of the field day activities. Additional evaluation of IPM programs is continuing.

Progress 09/01/10 to 08/31/11

Outputs
OUTPUTS: IPM coordination-The IPM coordinator has participated in two Southern Region IPM Center meetings, one SERA-03 meeting, 1 regional, and 1 national professional meeting. The coordinator developed and updated the Georgia IPM website and collaborated with IPM personnel to submit 11 proposals as the lead institution, and 5 proposals as collaborators. He is organizing a program evaluation workshop for the southeast to coordinate evaluation among SE IPM programs to provide stakeholders and government agencies with useful impact data. The coordinator has played an important role in production of the 2010 Georgia Pest Management Handbook (Commercial and Homeowners edition) and the Georgia Cotton Pest Management Newsletter. Peanut IPM- Peanut team members participated in 6 field days, and conducted over 50 county or multi-county education programs, and the yearly tri-state Peanut Diseases tour with Alabama and Florida. Eight presentations were given at regional or national professional meetings. Cotton IPM- The cotton team has produced 8 issues of the Cotton Pest Management newsletter and 7 issues of the Cotton Growers Newsletter. Cotton team members have conducted over 60 county or multi-county training events and have held 3 field day events. They have given 8 presentations at regional or national professional meetings. Team members have maintained the Cotton Insect Hotline (1-800-851-2847) which provides up to date management information for cotton insect pests. Brown Rot Management in Peaches- Effective demonstration of the Profile Resistance monitoring kit was continued for peach growers of Georgia and South Carolina. In an effort to transfer this fungicide resistance monitoring technique to a stand-alone program, project personnel have advertised to growers information for maintaining resistance monitoring. Testing materials will be available for a nominal fee. Information storage and analysis software will be housed on university servers and will be accessible to producers. Technical support will be available. Vegetable IPM- Vegetable team members conducted 37 county or multi-county extension training events with an average attendance of 30-50 people. Team members held 5 field day events reaching 200+ individuals, and served as organizers for the Southeast Regional Fruit and Vegetable conference. Seven presentations were given at regional or national professional meetings. All team members have active research/demonstration programs, with a total of 90 demonstration projects in 2010-2011. Diagnostics- The bugwood network received over 2.5 million hits on their website. Currently, the EDDMaps program, maintained by the center, is monitoring the spread of invasive species throughout the US. Two notable examples are the recently introduced plataspid bug Megacopta cribraria in GA, SC, AL, TN, and NC, and expanding boa constrictor populations in FL. This tool can be used for decision making at local, state, and regional levels.
