  1. Product File NotePart Ecotoxicology Ilse Pittomvils Federal Public Service of Public Health, Food Chain Safety and Environment Belgium

  2. Overview • Submitted studies • Labelling • Exposure • Risk assessment • Example Training Session Product File Notes and Registration Reports

  3. Submitted studies • see presentation of M. Guelton • two remarks: • Clearly indicate the units (e.g. 10 mg formulation/l or 10 mg active substance/l) because sometimes studies are carried out with the product but the endpoint is expressed in active substance • Always mention the most critical endpoint, for algae this is most often the EbC50 and not the ErC50 value Training Session Product File Notes and Registration Reports

  4. Labelling • Only labelling concerning ecotoxicology must be mentionned here • Use the most critical acute endpoints for labelling (e.g.algae: EbC50) • Most critical acute endpoint < 1 mg product/ l  R50 • 1 mg productl < Most critical acute endpoint < 10 mg/l  R51 • 10 mg productl < Most critical acute endpoint < 100 mg/l  R52 • Most critical acute endpoint > 100 mg product/l  no ecotox classification Training Session Product File Notes and Registration Reports

  5. Labelling (2) • R53 is assigned by default for a product with R50, 51 or 52 unless a biodegradability study reveals that this phrase is not necessary • Safety phrases • Professionals: S35-61 if R50 or 51 • S61 if R52 • Non-professionals: S29-56 if R50, R51 or 52 • If studies on non target arthropods: the product has no unacceptable effects on e.g. Typhlodromus pyri Training Session Product File Notes and Registration Reports

  6. Exposure (of aquatic organisms) • Excell sheet for cereals, maize = leafy crops, vegetables = grassland, herbicide in orchards in case of aquatic risk evaluation • to be used for all ‘horizontal’ cultivated plants i.e. vegetables, grains, grassland • To be used for herbicides • Excell sheet for grapevine • To be used for all ‘vertical’ cultivated crops i.e. grapes, small fruits, ornamentals, tomatoes, … • Excell sheet for orchards • To be used for apple, pear, … • Excell sheets for hops • To be used for hops Training Session Product File Notes and Registration Reports

  7. Exposure (2) • PEC-calculations: • By formula in the excell-sheet • Input data: concentration of a.s. in the product, application rate, number of applications, interval, DT50 • DT50 = 1000 unless data from water/sediment study are available • known DT50 for products with more than one a.s. : • if one a.s. is clearly more toxic than the other one: take the DT50 of the most toxic a.s. • if toxicity is related to both a.s., than take the worst case DT50 Training Session Product File Notes and Registration Reports

  8. Risk assessment • TER-calculation • TER = EC50 / PEC • Fish, daphnia: if TER > 100, then risk is acceptable • Algue: if TER > 10, then risk is acceptable Training Session Product File Notes and Registration Reports

  9. Example: Risk evaluation by means of the excell sheets Training Session Product File Notes and Registration Reports

  10. Example (2) • Information about the exposure: • Product X, 200 g/L a.s. • Intended use: • Apple: 2 x 1 L / ha leaf wall area  2 x 1,8 L / ha soil • applications before and after flowering • Grapevine: 2 x 1 L / ha • Potatoes: 2 x 1 L / ha Training Session Product File Notes and Registration Reports
