Guidance document on crop field trials

As such, it is designed to supplement Subdivision 0 of the Pesticide Assessment Guidelines:. Residue Chemistrv. Document Analyde e. Availability auuiiinH Unclassified and freely available. The SEPs are designed to ensure comprehensive and consistent treatment of major scientific topics in these reviews and to provide interpretive policy guidance where appropriate. While the documents were developed to explain specifically the principles of scientific evaluation within the Office of Pesticide Programs, they may also be used by other offices in the Agency in the evaluation of studies and scientific data.

The Standard Evaluation Procedures will also serve as valuable internal reference documents and will inform the public and regulated community of important consider- ations in the evaluation of test data for determining chemical hazards. I believe the SEPs will improve both the quality of science within EPA and, in conjunction with the Pesticide Assess- ment Guidelines, will lead to more effective use of both public and private resources.

Purpose of the Standard Evaluation Procedure 1. Background Information 1 C. Prepare a Summary 2 B. Identify Data Gaps 3 C. Assess the Appropriateness and Adequacy of the Data 3 D. This particular Standard Evaluation Procedure document addresses crop raw agricultural commodities. Background Information Crop field trials to provide residue chemistry data on the magnitude of the residue are required by 40 CFR Residue chemistry data on raw agricultural commodities r.

The term "total toxic residue" is used to describe the sum of the parent pesticide and its degradation products, metabolites free or bound , and impurities that are considered to be of toxicological significance, and therefore warrant regulation.

Statistical treatments of the data should be independently veri- fied and the quality control precautions noted. These should be duly noted in the reviewer's report, and a judgment made as to which are considered significant enough to adversely affect the review process.

The aforereferenced Data Submission Guidelines are a useful guide to the various parameters that need to be considered. Appendix 1 of this document discusses specific aspects of those parameters that warrant consideration. As an adjunct to these, the reviewer should draw upon the technical guidance in the reviewer aids materials that are available to him, such as the Residue Chemistry Guidelines a. Subdivision 0 of the Pesticide Assessment Guidelines. A listing of some suggested source materials is located in Appendix 2 to this document.

Those considerations are applicable whenever a r. A listing of some of the more useful references that reside within the Branch is provided in Appendix 2 to this document. Field Treatments and Harvesting 1. The R. Are the commercially important varieties represen- ted?

If so, are animal metabolism and feeding studies available? Note: these concerns will be addressed in separate Standard Evaluation Procedures to be developed in FY Is the r.

If so, have processing studies been conduc- ted? Footnote 1, page 1, this document. Note: Determining factors as to what constitutes "adequate geographic representation" include how widespread the crop is grown, its economic importance and national acreage, the range of conditions under which it is grown, whether a minor crop or minor use is involved, what the intended use pattern is, what data and tolerances exist on botanically related crops treated with the same pesticide via a similar use pattern, and the general concern over the toxicity of the pesticide.

Is this r. Permanent tolerance petition requests? What would be required for harmonization with any such IRL's?

Detailed consideration of this should be addressed in evaluating the formulation s ; this will be the subject of a separate Standard Evaluation Procedure to be developed in FY Has the active ingredient a.

Semiochemicals The European strategy for the sustainable use of pesticides focused the attention on means for crop protection, alternative to chemical insecticides where, among others, the semiochemical substances find their own place MORE INFO. Outputs from the 2nd World Congress on the use of Biostimulants The use of Biostimulants in agriculture is driven by the growing need to improve the yield and the quality of crops avoiding the overuse of pesticides and fertilizers according to the Integrated Pest and Crop Management.

Edge-of-field surface waters and their sediment dwelling organisms Environmental fate and behavior studies in water-sediment systems and the chronic toxicity tests on aquatic organisms represent the starting point to carry out an environmental risk assessment ERA concerning the sediment compartment.

Towards a definition of biostimulants! Biostimulants is a growing sector created to search alternative solutions to meet the increasing demand of safe and environmentally friendly food products MORE INFO. How to predict the environmental concentrations in soil… The comparison between the Predicted Environmental Concentration PEC derived from more or less sophisticated tiers and the relevant toxicity endpoints represents the risk assessment for the soil compartment.

Plant extracts: a different approach… The potential benefits from the historical uses of botanical active substances resulted in the contemporary tendency to reconsider their employment, in particular in the plant protection products, promoted as part of Integrated Pest Management strate MORE INFO.

Endocrine Disruptor substances: work in progress The identification and the evaluation of the endocrine disruptor substances EDs are becoming, and they will become, a high priority of the risk assessment in the European regulatory framework. Bees testing updates Pollination is a key service for the global agricultural production and, at the same time, it symbolizes the perfect symbiosis between plants and insects.
