Non Technical Summary
Small-acreage specialty crops occupy approximately 13.7 million acres in the United States. Sales of these crops are more than 67 billion dollars and make up approximately 40 percent of the total value of all U.S. crops. Growers of these minor crops, such as fruits, vegetables, herbs, and spices lack the availability of pesticides that are available to growers of major crops because the chemical registrants do not have the economic incentive to obtain the data necessary to register the pesticides on small acreage crops. Registrants are also concerned about product liability and will not register a use or will eliminate uses where liability is an issue. The USDA, with state agricultural experiment stations (SAES), recognized this problem in 1963 when they organized the Interregional Research Project Number 4 (IR-4) to assist specialty crop producers obtain EPA tolerances and new registered uses for pest control products. The IR-4 Project is the only publicly-funded program that conducts research and submits petitions to EPA to establish new tolerances and labeled uses for specialty crop growers. Growers are gradually losing many of the pest management tools they previously had because of regulatory issues such as the Food Quality Protection Act (FQPA) and other environmental concerns. There is a greater impact to growers of minor crops than those of major crops such as cotton, corn, soybeans and wheat. In the IR-4 program, federal scientists and state scientists work with growers, with researchers, and with extension personnel to identify minor use pesticide needs and with U.S. EPA to identify the data requirements to obtain clearances. This program is coordinated across the entire United States and Canada with 23 field research units in 18 states and 4 provinces and 5 analytical laboratories. The NCSU IR-4 Field Research Center was established in 1994 as part of this network. The IR-4 program concentrates its efforts on reduced risk pesticides as safer alternatives for minor crops.

Goals / Objectives
Conduct magnitude-of-residue and performance/crop tolerance trials to generate suppoeting data used by US EPA to establish allowable residues for pest control products in minor/specialty crops.
Project Methods
Magnitude-of-Residue trials will be conducted under Good Laboratory Practices, or GLPs (40 CFR Part 160 - Federal Insecticidde, Fungicide and Rodenticide Act (FIFRA); Good Laboratory Practice Standards; Final Rule, August 17, 1989). These guidelines are federally mandated to ensure consistency of trial execution across locations. If there is a high level of consistency in the trial execution, there will be more consistent residue levels and will expedite the registration or reregistration decision on a given compound by US EPA. These guidelines require high levels of documentation for all equipment and procedures used to conduct a magnitude-of residue trial, including logs of all activities involved in the trials (personnel training, equipment and instrument calibration/use/cleaning/maintenance, chain-of-custody for any data and/or sample exchanges, etc.) Approved Standard Operating Procedures (SOPs), both IR-4 global and facility-specific, must be followed. Any discrepancy from these and/or the study protocol requirements must be captured and communicated to IR-4 administration. Sufficient GLP training, both external and in-house, will be obtained by all individuals participating in Magnitude-of-Residue trials conducted at the NCSU IR-4 Field Research Center. All Magnitude-of-Residue trial data are thoroughly scrutinized through both Quality Control (QC) and Quality Assurance (QA) review prior to submission to US EPA. Additionally, both facility and trial-specific inspections are made regularly by the IR-4 QA Unit. Since 2005, the NCSU IR-4 Center has undergone 3 separate EPA audits with no negative findings. Performance/crop safety trials will be conducted according to standard agricultural research practices, including but not limited to: rate range evaluations, multiple replications of treatments and use of proper statistical design and analysis. These trials generally involve multiple compounds and/or rates with at least 3 replications of each treatment. Applications are generally made with a CO2-pressurized backpack sprayer. Measured parameters typically include crop phytotoxicity, pest control evaluations at several intervals and crop yield.

There are increased indirect costs at cooperating universities, including severed relations with at least one univerisity over indirect costs. Other policies at cooperating univerisities have also pulled resources away from the mission of helping growers.

            Outputs
            OUTPUTS: The registration of crop protectants for fruit and vegetable crops has traditionally not been profitable for chemical manufacturers to pursue. The high cost of development and research to get a product registered for use requires manufacturers to focus on large acreage crops such as corn, soybeans, cotton, etc. In order for products to get registered for use on fruit and vegetable crops, the IR-4 program must develop and submit data packages to establish crop tolerances. The potential exists for significant crop losses due to inadequate pest control product availability unless data is generated to support registration of new, reduced risk crop protectants. In 2011, 26 field residue trials and 10 crop tolerance/performance trials were performed at the NC State IR-4 Field Research Center. These trials were conducted to support registration and re-registration of pest control products and to determine potential pest control products that may eventually be labeled in minor crops based on performance and crop safety. PARTICIPANTS: Nothing significant to report during this reporting period. TARGET AUDIENCES: Nothing significant to report during this reporting period. PROJECT MODIFICATIONS: Nothing significant to report during this reporting period.

            Impacts
            Data collected from the residue trials will support pest control product registration in the following crops: canola, blueberry, bell pepper, leaf lettuce, asparagus, cucucmber, southern pea, lima bean, peach, head lettuce, cantaloupe, basil, tomato, non-bell pepper, turnip, caneberry, and strawberry. By using the EPA system of crop grouping, the data from these trials may lead to registration in many more crops as well. Many of these trials were with reduced risk pest control products.

            Impacts
            Data from NCSU IR-4 Field Research Center helped to re-establish the use of Gramoxone Inteon (paraquat) and gain initial registrtions for Select Max (clethodim) and Linex (linuron) as herbicides in clary sage production in North Carolina. Efforts are continuing to identify more possible herbicides in this valuable crop. In 2008, various specialty crops gained tolerances (maximum residue levels) or labels using, in part, data from research conducted at the NCSU IR-4 Field Research Center: spiromesifen/dry and succulent bean, chlorantraniliprole/peach, pendimethalin/strawberry, forchlorfenuron/blueberry, buprofezin/pepper, bifenthrin/blueberry, fludioxinil/sweetpotato, methoxyfenozide/sweetpotato, flumioxazin/pecan, indoxacarb/peach, flumioxazin/blueberry, flumioxazin/canataloupe, buprofezin/strawberry, flumioxazin/pepper, methoxyfenozide/peanut, methoxyfenozide/blueberry, methoxyfenozide/grasses, indoxacarb/cucumber, indoxacarb/pea, myclobutanil/pepper, bifenazate/bean, cyprodinil + fludioxinil/tomato, cyprodinil + fludioxinil/strawberry, metaldehyde/blueberry (reregistration), and fluroxypyr/apple.
