[0363] Leaves of vine plants, Merlot variety, grown in pots, in a conditioned environment (20?1? C., 70% R.H.) were treated by spraying both sides of the leaves with the products in question.
[0364] 7 days after the treatment, the plants were inoculated with an aqueous suspension of Plasmopara viticola spores (200,000 spores/cc) by spraying both sides of the leaves with a compressed air gun.
[0365] After remaining 24 hours in a humidity-saturated environment, at 21? C., the plants were transferred for the incubation period (7 days) in a conditioned environment with 70% R.H. and at 24? C.
[0366] After this period of time, the external symptoms of the pathogen appeared and it was therefore possible to evaluate the intensity of the infection.
[0367] The fungicidal activity is expressed as a percentage of the reduction, compared to untreated seedlings, in the area of the leaf area affected by the disease (100=complete effectiveness, 0=zero effectiveness).

[0370] Leaves of wheat plants of the Salgemma variety, grown in pots in a conditioned environment at 20? C. and 70% of Relative Humidity (RH), were treated by spraying both sides of the leaves with the compound under examination dispersed in a hydroacetone solution at 20% by volume of acetone.
[0371] After remaining 5 days in a conditioned environment, the plants were sprayed on both sides of the leaves with an aqueous suspension of conidia of Puccinia Recondita (2 mg of inoculum per 1 ml of solution for infection).
[0372] After spraying, the plants were kept in a humidity-saturated environment at a temperature ranging from 18 to 24? C. for the incubation period of the fungus (1 day).
[0373] At the end of this period, the plants were put in a greenhouse with a relative humidity (RH) of 70% and at a temperature of 18-24? C. for 14 days
[0374] At the end of this period, the external symptoms of the pathogen appeared and it was therefore possible to proceed with the visual evaluation of the intensity of the infection, both on the parts treated directly with the products (T) and on the parts developed during the implementation of the test (NT).
[0375] The fungicidal activity is expressed as a percentage of the reduction, with respect to non-treated seedlings (blank), in the area of the leaf affected by the disease (100=full effectiveness; 0 =zero effectiveness).
[0376] All of compounds Nr. 46, 156, 165 and 249 showed an activity greater than 80% at a dose of 250 ppm.
[0377] At the same time, an evaluation of the phytotoxicity was effected (percentage of leaf necrosis) induced on the wheat seedlings by the application of the products: in this case the evaluation scale ranges from 0 (completely healthy plant) to 100 (completely necrotic plant).

[0379] Leaves of soya plants of the Zora variety, grown in pots in a conditioned environment at 20? C. and 70% of Relative Humidity (RH), were treated by spraying both sides of the leaves with the compound under examination dispersed in a hydroacetone solution at 20% by volume of acetone.
[0380] After remaining 5 days in a conditioned environment, the plants were sprayed on both sides of the leaves with an aqueous suspension of conidia of Phakopsora pachyrhizi (50 mg of urediniumspore in 100 ml of demineralized water with the addition of a drop of Tween surfactant).
[0381] After spraying, the plants were kept in a humidity-saturated environment at a temperature ranging from 18 to 24? C. for the incubation period of the fungus (1 day).
[0382] At the end of this period, the plants were placed in a climatic cell with R.H. 70% and a temperature of 22-24? C. for 12 days
[0383] After this period of time, the external symptoms of the pathogen appeared and it was therefore possible to proceed with the visual evaluation of the intensity of the infection, as a percentage of the leaf surface affected, considering both the two basal leaves and the first trifoliate leaf.
[0384] The fungicidal activity is expressed as a percentage of the reduction, with respect to non-treated seedlings (blank), in the area of the leaf affected by the disease (100=full effectiveness; 0=zero effectiveness).
[0385] All of compounds Nr. 46, 156, 165 and 249 showed a complete control of the pathogen at a dose of 125 ppm and a control exceeding 80% at 30 ppm.
[0386] At the same time, an evaluation of the phytotoxicity was effected (percentage of leaf necrosis) induced on the soya seedlings by the application of the products: in this case the evaluation scale ranges from 0 (completely healthy plant) to 100 (completely necrotic plant).

EXAMPLE 20
Determination of the Antifungal Activity In Vitro of Compounds Having Formula (I)
[0387] The molecules having general formula (I) were tested to evaluate their antifungal activity in vitro against the following fungi and straminipila: Alternaria alternata, Botrytis cinerea, Cercospora beticola, Colletotrichum lindemuthianum, Drechslera graminea, Fusarium graminearum, Magnaporthe oryzaena Monilia fructigena, Parastagonospora nodorum, Phytophthora infestans, Pythium ultimum, Rhizoctonia solani, Sclerotinia sclerotiorurn, Ustilago maydis, Venturia inaequalis and Zymoseptoria tritici.
[0388] The pure culture isolates were kept and stored at 4? C. in a refrigerator on agarized nutrient substrates suitable for each of them. For effecting the activity assays, the inoculum was prepared which, depending on the species of the pathogen, could be a suspension of conidia or a mycelial homogenate. For strains not easily sporulating in vitro, six to eight mycelium plugs were transferred to a grinding egg containing 6 ml of Potato Dextrose Broth (PDB) 2? and some metal balls. The suspension was homogenized with a Pulverisette 23 mini-mill (Fritsch GmbH).
[0389] For all the sporulating strains in vitro, the conidic suspension was prepared starting from a culture grown on a suitable agarized medium and under suitable conditions for stimulating sporulation. The conidia were collected in 1 ml of PDB 2? and counted under a microscope with a counting chamber in order to obtain a final inoculation of 2?10.sup.4 conidia/ml.
[0390] The concentrations tested for each active molecule were 0.001, 0.01, 0.1, 1,5 and 10 mg/l. For each molecule to be tested, a mother solution in dimethylsulfoxide (DMSO) at 80,000 mg/l was prepared which was then serially diluted in sterile demineralized water to obtain the solutions to be tested in double concentrations compared to the final doses. The inhibition tests were carried out in 96-well plates: 50 ?l of inoculum were mixed with 50 ?l of the active molecule solution in each well using the Eppendorf Multipette? System E3 serial dispenser. Four wells were used as replicates for each concentration of active ingredient. All the strains of the pathogens were grown in untreated control wells containing 50 ?l of fungal suspension and 50 ?l of sterile demineralized water. The inoculated multi-well plates were incubated at 20? C. for 72 hours (96 or 120 when necessary).
[0391] The sensitivity to the molecules was assessed as a growth inhibition of the fungus and measured in terms of absorbance immediately before and after the incubation period.
[0392] The absorbance was measured for each well using an Infinite? F50 Absorbance Reader (Tecan Group Ltd) spectrophotometer at 405 nm (for mycelial inoculae) and 492 nm (for conidic inoculae).
[0393] For each strain, the growth inhibition percentage (GIP) caused by each of the concentrations of the active ingredient was calculated using the following formula:
[0394] wherein At.sub.72-120 and At.sub.0 are respectively the absorbances of the treated and untreated well measured at the end and at the beginning of the incubation period. The GIP data were used for calculating EC.sub.50 which are, respectively, the effective concentrations (mg/l) of active molecule that reduce mycelial growth by 50% compared to the untreated control.
[0395] Table 11 indicates the results obtained by carrying out the test described with compounds Nr. 46, 165, 236, 239 and 248 and with the compound CR2 described in WO2016/109257 (Nr.112)

Compound Nr.165 having general formula (I) wherein R, represents the formylaminosalicylic group, showed with respect to the identical reference compound CR2 described in patent WO2016 109257 (compound 112), wherein however R.sub.c represents a hydrogen atom, an improved in vitro antifungal activity with respect to both effectiveness and spectrum of action. Compound Nr. 165, in fact, was found to be active both against pathogens belonging to the Straminipila kingdom such as P. infestans and P. ultimum and also against other important phytopathogenic fungi such as M. oryzae and V. inaequalis. Furthermore, with respect to the effectiveness, it can be observed that for all the phytopathogenic fungi tested, the EC.sub.50 values obtained from compound Nr. 165 are much lower than those indicated by compound CR2, therefore proving to be much more active than the product belonging to the known art.
