1. SUMMARY The trial was carried out on Potato [Solanum tuberosum L. var. Universa], on field-grown, in Sourthern Italy (Sicilia), locality Augusta (SR), according to an experimental design with non-randomized blocks, side-byside, length-wise layout and 1 replications. They were compared three theses: 1. Untreated check: (UTK): fertilization background with an organo-mineral and granular NP distributed for sowing; 2. Treatment (TRT): fertilization background with organo-mineral and granular Micosat F at a dose of 30 kg / ha seed distributed. One month after the collection has been carried out with an application Micosat F Tab Plus, in fertirrigation, at a dose of 2 kg / ha. 3. Treatment NP (TRT-NP): background with organic-mineral fertilization and a granular NP together with the microgranular Micosat F, the latter always at a dose of 30 kg / ha sowing. One month after the harvest has been carried out with an application Micosat F Tab Plus, in fertirrigation, at a dose of 2 kg / ha. 2. EXPERIMENTAL CONDITIONS 2.1 Objective of the trial The primary objective of the trial was to determine the efficacy and selectivity of Micosat F, in Italy for increases in production on Potato against the Untreated check.. 2.2 GEP compliance The study was done according to the EPPO guidelines and Standard Operating Procedures POS of the Testing Facility: Guidelines Discipline Title Number PP 1/135 (3): General Standards Phytotoxicity assessment PP 1/152 (3) General Standards Design and analysis of efficacy evaluation trials PP 1/181 (3) General Standards Conduct and reporting of efficacy evaluation trials including good experimental practice The study described in this report was conducted in compliance with the principles of Good Experimental Practice (GEP) as defined by guideline 91/414/CEE of the European Union.

4. ASSESSMENTS 4.1 Mode of assessment, recording and measurement The measurements were carried out on all plants in the plot, considering the number of tubers, the diameter and the yield per plot. 4.2 Type, time and frequency of assessment Tab.5: Average number of tubers per treatment Treatments Rate Kg/ha 17/04/2013 128 DAT1 0 DALA 13/05/2013 154 DAT1 19 DTA2 26 DALA 1 Untreated check - 3 5 2 TRT Without NP 3 TRT-NP With NP Micosat F VS Micosat F Tab Plus Micosat F VS Micosat F Tab Plus 30-2 30-2 4,5 6 4 8 Assessment of 17-04-2013 From a visual examination, the first assessment shows that the tubers on untreated check are less in number compared to the treated, are also of minor size, where as missing about a month (- 40 days) to the harvest, everything suggests that the tubers will continue to grow. The Treated has a greater number of tubers per plant (No.4,5), larger than the untreated check and uniform size. The Treated-NP has more tubers per plant (No. 4) compared with the Untreated check, all of uniform size, so the comparison is the best. 11

Assessment of 13/05/2013 The results of assessments show: Untreated check (UTK): n 5 tubers per plant; Treatment (TRT): n 6 tubers per plant; Treatment NP (TRT-NP): n 8 tubers per plant. The Treated NP has all uniform tubers, the Treated has tubers greater size than the Treated NP and the Untreated check. Fig. 3 Untreated check (UTK) 13

Fig. 5 TRT-NP Assessments on Harvest Harvest was made on 25-05-2013, the number of boxes per plot was counted the values obtained are showed and summarized in Table 7: 1. UTK were harvested n 64 boxes, the yield per plot was made of 1449.92 Kg, the production per hectare of about 420 q. 2. TRT: were harvested No. 76 boxes, the yield per plot was 1831.90 kg, the production per hectare of about 540 q. 3. TRT NP were harvested n 70 boxes, the yield per plot was 1856.75 Kg, the production per hectare of about 546 q.li. 15

5 CONCLUSIONS In the plots with mycorrhizae there was a higher production compared to the untreated, in particular the 26 % more in the plot named "Treated" and 28 % more in the plot named " Treated NP ". The difference in production between the two plots with mycorrhizae was minimal, the 1,3% more in one named " Treated NP " In qualitative terms, however, the production obtained in the " Treated " was higher, in fact over 90% (see graphics ) consisting of tubers calibre between 45 and 70 mm (the most demanded by the market ). While in the "Treated NP " the effect of fertilization with granular NP was probably "exalted " by mycorrhization, infact about 21 % of the production consists of large size, tubers> 70 mm.finally in untreated check the higher incidence of tubers with caliber of 28 to 45 mm was found, which suggests that the basal fertilization was definitely integrated.

The Untreated check was manifested presence of Phytophthora infestans, Alternaria solani and Rhizoctonia solani. This justifies the increases in production recorded in the treatments (thesis n. 2 and 3). Fig. 12: Harvesting and selection in box Fig. 13: Harvesting and selection in box 27
