Methods of analysis 3..1 Analytical method for the formulation Not relevant for extension of authorisation according article 51. 3..2 Analytical methods for residues The intended commodities belong to the group of high water content commodities. Sufficiently validated analytical methods are available for enforcing metalaxyl-m, mancozeb and dithiocarbamates. 3.1.3 Mammalian Toxicology The PPP is already registered in Germany according to Directive 91/414/EEC. If used properly and according to the intended conditions of use, adverse health effects for operators, workers, bystanders and residents will not be expected. 3.1.4 Residues and Consumer Exposure The residue behaviour of the active substances Metalaxyl-M and Mancozeb have been evaluated within the EU review process. Information about metabolism is sufficient to evaluate the intended uses. 3.1.4.1 Residues The available residue information is sufficient to perform an adequate assessment. Residues that are expected from the intended use of the plant protection product will not exceed the MRL set in Regulation (EC) No 396/2005 for metalaxyl-m and mancozeb except for endives and other open lettuce varieties. For these crops additional residue data are asked for. Before authorisation the intended use (006) has been changed to head lettuce and iceberg lettuce. 3.1.4.2 Consumer exposure An assessment of residue uptake by consumers (TMDI calculation, EFSA PRIMo) results in the following maximum ADI consumptions: Dithiocarbamates (Mancozeb: 0.05 mg/kg bw/d) 72 % (DE children) Metalaxyl-M (0.08 mg/kg bw/d) 26 % (DE children) Long-term dietary intake of residues of Metalaxyl-M and Mancozeb is unlikely to present a public health concern for European consumers. No acute risk is expected from the consumption of the intended commodities treated according to the intended use.

The PPP Ridomil Gold MZ and the active substance mancozeb are toxic to the aquatic environment (mesocosm: NOEC 3.2 µg a.i./l). Subsequently no additional entries as those according to the evaluated use pattern and good agricultural practise are acceptable. Therefore the safety phrases and conditions of use NW262, NW264, NW468 and NW 605-1/NW606 are assigned, see also 2.2. The risk assessment with regard to effects on birds is based on a NOEL of 18.8 mg as/kg bw/d (Anas platyrhynchus tested with Dithane M 45 80,1 % Mancozeb). Together with the relevant focal species according to the EFSA guidance document EFSA/2009/1438 the acceptability criteria of a TER of 5 is reached for all scenarios relevant. Risk Assessment for Honeybees The honeybee risk assessment for the main application covers the use(s) in accordance with Article 51 of regulation (EC) No 1107/2009 (see also point 2.2). 3.1.7 Efficacy Labelling in accordance with the requirements of ANNEX III General principles of integrated pest management under directive 2009/128/EC (see also point 2.2): -The classification of effects on beneficial arthropods for the main application covers the use(s) applied for under the terms of Article 51 of regulation (EC) No 1107/2009. -The categories and labelling for mode of action for the main application cover the use(s) applied for under the terms of Article 51 of regulation (EC) No 1107/2009. According to Article 51 of the regulation (EC) No 1107/2009 the requirements for approval concerning the sufficient effect and any unacceptable effects on plants and plant products not need to be checked. BVL_FO_05_2422_200_V1.0 3.2 Conclusions PPP Ridomil Gold MZ is already registered in Germany according to Directive 91/414/EEC taking into account the uniform principles of Annex VI. The intended use is minor in nature and the extension of authorisation is in public interest. Effects on bees and other beneficials were evaluated in the frame of the already authorised uses. No additional effects are anticipated because of the extension of uses. The intended use in bulb vegetables, beans, leeks, head lettuce, iceberg lettuce and fresh herbs, will not result in residues above the MRLs set in Regulation (EC) No 396/2005. A risk for consumers through the consumption of food with these residues is not expected. There is no special risk mitigation necessary which deviate from the existing registration. With respect to fate and ecotoxicology assessment, an authorisation can be granted. Considering an application in accordance with the evaluated use pattern and good agricultural practice as well as strict observance of the conditions of use no harmful effects on groundwater or adverse effects on the ecosystem are to be apprehended. An authorisation is foreseen for all uses. Applicant Pflanzenschutzdienst der Landwirtschaftskammer Nordrhein-Westfalen Date: 04/07/2016

The results can be extrapolated to endives. As endive is a minor crop four trials are necessary for each active substance. For Mancozeb two suitable results are available.

4 METABOLISM AND RESIDUES DATA 4.1 Evaluation of the active substances 4.1.1 Mancozeb Table 4.1-1: Identity of the active substance mancozeb Structural formula Mn S H N H N S Zn y S S x Common Name Mancozeb (polymeric complex of the monomer illustrated above which contains 20 % manganese and 2.5 % zinc) CAS number 008018-01-7 4.1.1.1 Storage stability A brief summary of the storage stability data on mancozeb is given in the following table. Data has been previously evaluated at EU level and is described in detail in the DAR (ASB2010-10168) and in EFSA s Reasoned Opinions on the Modification of the existing MRL for mancozeb in radishes (EFSA Journal 2011;9(3):2108; ASB2012-3286) and on the Modification of the existing MRL for mancozeb in fresh peas without pods (EFSA Journal 2010; 8(1):1451; ASB2012-3447). Table 4.1-2: Stability of residues (Annex IIA, point 6.1) Stability of mancozeb and ETU Residues of mancozeb are stable in apples, tomatoes and wheat under deep freezer conditions (-20 C) for up to two years (RIP2000-752). Residues of ETU are moderately stable under conditions of frozen storage: for up to 12 months in tomatoes and wheat and for up to 6 months in apples (RIP2000-752). 4.1. Metabolism in plants and plant residue definitions A brief summary of the metabolism of mancozeb in plants is given in the following table. Data has been previously evaluated at EU level and is described in detail in the DAR (ASB2010-10168) and in EFSA s Reasoned Opinions on the Modification of the existing MRL for mancozeb in radishes (EFSA Journal 2011;9(3):2108; ASB2012-3286) and on the Modification of the existing MRL for mancozeb in fresh peas without pods (EFSA Journal 2010; 8(1):1451; ASB2012-3447).

Table 4.1-3: Metabolism in plants (Annex IIA, point 6.2.1; 6.5.1, 6.5.2, 6.6.2 and 6.7.1) Plant groups covered Rotational crops Metabolism in rotational crops similar to metabolism in primary crops? (yes/no) Distribution of the residue in peel/ pulp Processed commodities (nature of residue) Residue pattern in raw and processed commodities similar? (yes/no) Plant residue definition for monitoring Soybeans (oilseeds, RIP2000-753,RIP2000-828), tomatoes (fruiting vegetables,rip2000-829), potatoes and sugar beets (root and tuber vegetables, RIP2002-838 and RIP2000-827) and wheat (cereals, RIP2000-830, RIP2000-831), all as foliar applications, 14 C- ethylene label. Metabolism studies in four different crop groups indicate extensive degradation in plants and incorporation of the majority of radioactivity into naturally occurring molecules such as sugars (up to 41 % TRR), starch (up to 27 % TRR), proteins and amino acids (up to 45 % TRR), oil or lipids (up to 14 % TRR) and lignin (up to 23 % TRR). Residues of the toxicologically significant metabolite ETU were mostly below the LOQ except for potatoes (0.0007 mg/kg). Incorporation into natural products proceeds either through glycine or through enzyme-catalysed, oxidative cleavage into single carbon units derived from the radiolabelled ethylene backbone of mancozeb. It was concluded that metabolism was similar in all crops and that mancozeb is the only relevant residue in unprocessed primary crops. Barley (cereals), potatoes and radishes (root and tuber vegetables), Swiss chard (leafy vegetables): soil application at a rate of 6.7 kg as/ha, 14 C- ethylene label (RIP2005-2211) Only low residues were determined at harvest in rotational crops: 0.02-0.075 mg/kg after PBI of 30 days and 0.01-0.06 mg/kg after PBI of 60 days. Residues of the metabolite ETU were not detected in rotational crops. Due to the low residues no further characterisation was performed. Not concluded, since only low residues were determined in rotational crop study. Not applicable Studies on the effects of processing on the nature of mancozeb residues showed that the only degradation product of toxicological significance is ethylenethiourea (ETU). It particularly occurs after heating. For processed commodities a consumer risk assessment has to be performed regarding the potential consumer health risk related to ETU (see DAR, ASB2010-10168). No Since no specific analytical methods are available for the individual active substances belonging to the dithiocarbamate group, a common residue definition was established for dithiocarbamates: Dithiocarbamates expressed as CS 2, including maneb, mancozeb, metiram, propineb, thiram and ziram. This is in line with Reg. (EC) No 396/2005. Page 5 / 68

Data has been previously evaluated at EU level and is described in detail in the DAR (ASB2010-10168). Table 4.1-4: Metabolism in livestock (Annex IIA, point 6.2.2 to 6.2.5 and 6.7.1) Animals covered Lactating goats (RIP2000-918, RIP2000-919), laying hens (RIP2000-920, RIP2000-921), 14 C-ethylene label, 7 days, three feeding levels: 4, 20 and 50 mg/kg feed In goats mancozeb is extensively metabolised and excreted fast via feces and urine with only minor amounts remaining in milk and tissues. The carbon atoms are incorporated to a significant extent into natural components (fat, protein, and carbohydrates) of milk and tissues. Time needed to reach a plateau concentration in milk and eggs Animal residue definition for monitoring The metabolism of mancozeb in hens is not significantly different from its metabolism in goats. Most of the radioactivity was excreted and only low residues were determined in tissues and eggs with highest levels in kidney and liver. Residues declined immediately after cessation of administration. 14 C was present in natural substances, as well as in metabolites. Ethylene urea (EU) was the most abundant metabolite in eggs or tissues, while ETU was detected only in traces. Milk: 3 days Eggs: plateau concentration was not achieved during dosing period of 7 days Since no specific analytical methods are available for the individual active substances belonging to the dithiocarbamate group, a common residue definition was established for dithiocarbamates: Animal residue definition for risk assessment Conversion factor(s) (monitoring to risk assessment) Not applicable Metabolism in rat and ruminant similar (yes/no) Dithiocarbamates expressed as CS 2, including maneb, mancozeb, metiram, propineb, thiram and ziram. This is in line with Reg. (EC) No 396/2005. Dithiocarbamates expressed as CS 2, including maneb, mancozeb, metiram, propineb, thiram and ziram, and ETU. Yes Fat soluble residue: (yes/no) No, log P O/W = 1.33 4.1.1.4 Residues in rotational crops Field rotational crop studies on mancozeb are not required. This is explained in the following table. Page 6 / 68
Table 4.1-5: Residues in rotational crops (Annex IIA, point 6.6.3) Field studies Based on the metabolism study on rotational crops and on the DT 90 of mancozeb in soil of approximately one day, no significant residues are expected to occur in rotational or succeeding crops grown in areas previously treated with mancozeb. 4.1.1.5 Residues in livestock Residues of mancozeb in commodities of animal origin were not assessed, since crops under consideration are normally not fed to livestock. 4. Metalaxyl-M Table 4.1-6: Identity of the active substance metalaxyl-m Structural formula Me Me N H R CO 2 Me Me Common Name Metalaxyl-M CAS number 70630-17-0 O OMe 4..1 Storage stability A brief summary of the storage stability data on metalaxyl-m is given in the following table. Data has been previously evaluated at EU level and is described in detail in the DAR (ASB2010-10523) and EFSA s Reasoned Opinion regarding the review of the existing MRLs for metalaxyl-m (ASB2012-3201). Table 4.1-7: Stability of residues (Annex IIA, point 6.1) Stability of metalaxyl-m Storage stability of metalaxyl-m was demonstrated for a period of 30 months at -20 C in commodities with high water and high acid content, and for a period of 24 months in high oil content commodities and dry commodities (ASB2012-3201). Further studies on metalaxyl were available also demonstrating stability over the tested storage periods. 4..2 Metabolism in plants and plant residue definitions A brief summary of the metabolism of metalaxyl(-m) in plants is given in the following table. Data has been previously evaluated at EU level and is described in detail in the DAR (ASB2010-10523) and EFSA s Reasoned Opinion regarding the review of the existing MRLs for metalaxyl-m (ASB2012-3201). All plant metabolism studies (primary and rotational crop studies) were conducted with [ 14 C-phenyl]- metalaxyl. One study comparing the metabolism of metalaxyl-m and metalaxyl was performed on lettuce, showing a similar pattern for the R-enantiomer and the racemic mixture. Page 7 / 68

(RIP2000-642, RIP2000-643, RIP2000-644, RIP2000-645) Rotational crops The metabolism data on metalaxyl can also be applied to metalaxyl-m. Uptake following root, stem or leaf application is fast and translocation primarily occurs acropetally. Metalaxyl(-M) was intensively metabolised in all investigated crops with up to 8 identified metabolites. At harvest, parent metalaxyl accounted for 64 % TRR in grapes, 20 % TRR in lettuce, and 3 % TRR in potato leaves. Metabolite CGA 94689, free and conjugated, accounted for 20 % TRR in grapes and 25 % TRR in lettuce. In potato leaves CGA 108905 amounted to 47 % TRR. All other metabolites were seen at <10 % TRR. Metabolites mainly consisted of hydroxylated or demethylated parent, which are considered as less toxic than the parent.

(yes/no) Plant residue definition for monitoring Plant residue definition for risk assessment In crops planted immediately after harvest of treated potatoes, TRR levels at harvest were >0.1 mg/kg in wheat (0.11 mg/kg in grain, 0.56 in straw), soybean (0.17 mg/kg in beans, 0.59 in leaves), lettuce (0.11 mg/kg) and oats (0.19 mg/kg in straw). In corn, oat grain and sugar beet, TRR was below 0.1 mg/kg. In crops planted after tobacco which had received a soil treatment, 79% TRR in mature wheat stalks, 57% TRR in 50 % mature lettuce and 57 % TRR in mature sugar beet root had been charactewrised and/or identified. Seven glycosides were isolated and identified. Parent was extensively metabolized but still remained an important compound of the residue in the 50% mature lettuce foliage (15% TRR). The metabolite CGA 6786813 present in wheat stalks (6.8% TRR) and lettuce foliage (15.5% TRR) was neither detected in plants nor in the rat metabolism. yes No information available. Simulated processing studies on the nature of metalaxyl residues demonstrated that under standard processing conditions (ph 4, 90 C, 20 min; ph 5, 100 C, 60 min; ph 6, 120 C, 20 min) the compound is hydrolytically stable (RIP2004-999). yes metalaxyl including other mixtures of constituent isomers including metalaxyl-m (sum of isomers) This is in line with Reg.

Table 4.1-9: Metabolism in livestock (Annex IIA, point 6.2.2 to 6.2.5 and 6.7.1) Animals covered Lactating goats: [phenyl-u- 14 C]-metalaxyl, 77 mg/kg diet (3.9 mg/kg bw/d), 4 days (RIP2000-651, RIP2000-652, RIP2000-653) Time needed to reach a plateau concentration in milk and eggs Lactating goats excreted 67 % of the administered dose via urine. Metalaxyl was intensively metabolised. The metabolic transformation involves oxidation and demethylation of the parent compound. In milk and edible tissues unchanged parent was not found. CGA 107955 (N- (2,6 dimethylphenyl)-n-(hydroxyacetyl)-alanine) was the major metabolite in liver (13.5 %; 0.22 mg/kg), kidney (31.5 %; 0.33 mg/kg), fat (29.6 %; 0.12 mg/kg), and muscle (18.4 %; 0.01 mg/kg). The glucorinic conjugate of CGA67869 (N-(2,6 dimethylphenyl)-n-(hydroxyacetyl)- alanine methylester) represented 67.5 % of the milk residues (0.28 mg/kg). Laying hens: [phenyl-u- 14 C]-metalaxyl, 100 mg/kg diet (6 mg/kg bw/d), 4 days (RIP2000-654, RIP2000-655) With the majority of the radioactivity recovered in the excreta (91 %) transfer of radioactivity to eggs/tissues was relatively low. Highest levels were found in kidneys (1.47 mg/kg) and liver (1.39mg/kg). The parent compound was almost completely degraded and, if present, only at low levels (<0.01 18.6 % TRR). The remaining residue comprised a large number of distinct metabolites, out of which CGA 107955 was the major one (40.3 % TRR in fat, 17.1 % in liver, 14.5 % in egg yolk). An accumulation has not been observed in any tissue. 1 day Animal residue definition for monitoring Current definition according to Reg.
