Abstract
Description
Invenţia se referă la chimie şi agricultură, şi în special la utilizarea unui derivat cuaternar al 1,2,4-triazolului în calitate de remediu fungicid contra fungilorFusarium avenaceumşiFusarium oxysporum. The invention relates to chemistry and agriculture, and in particular to the use of a quaternary derivative of 1,2,4-triazole as a fungicidal remedy against the fungi Fusarium avenaceum and Fusarium oxysporum.
FungiiF. avenaceumşiF. oxysporumsunt agenţi patogeni ai putregaiului de rădăcină la grâu şi ai maladiilor spicelor la culturile păioase (Lupaşcu G. Putregaiul de rădăcină la grâul comun de toamnă. Chişinău: Print-Caro, 2020, 120 p.). The fungi F. avenaceum and F. oxysporum are pathogens of root rot in wheat and ear diseases in grassy crops (Lupaşcu G. Root rot in common autumn wheat. Chişinău: Print-Caro, 2020, 120 p.).
Conform datelor recente, contaminarea crescută a culturilor de grâu şi orz din Europa şi Asia cu micotoxine emergente, cum ar fi eniatinele sau bovericina, produse deF. avenaceumsugerează că această specie ar putea fi implicată în viitoarele crize de siguranţă alimentară (Ponts N., Gautier Ch., Gouzy J. et al. Evolution ofFusarium tricinctumandFusarium avenaceummitochondrial genomes is driven by mobility of introns and of a new type of palindromic microsatellite repeats. BMC Genomics, BioMed Central, 2020, 21(1), 358 (10.1186/s12864-020-6770-2). According to recent data, the increased contamination of wheat and barley crops in Europe and Asia with emerging mycotoxins, such as eniatins or bovericin, produced by F. avenaceum suggests that this species could be involved in future food safety crises (Ponts N., Gautier Ch., Gouzy J. et al. Evolution of Fusarium tricinctum and Fusarium avenaceum mitochondrial genomes is driven by mobility of introns and of a new type of palindromic microsatellite repeats. BMC Genomics, BioMed Central, 2020, 21(1), 358 (10.1186/s12864-020-6770-2).
Întrucât speciile Fusarium, ca şi multe alte micromicete, uşor se adaptează la preparatele chimice utilizate în măsurile de protecţie a plantelor, sunt deosebit de actuale cercetările cu privire la identificarea noilor compuşi cu activitate antifungică, ceea ce a şi prezentat scopul prezentelor investigaţii. Since Fusarium species, like many other micromycetes, easily adapt to chemical preparations used in plant protection measures, research on the identification of new compounds with antifungal activity is particularly relevant, which is the purpose of the present investigations.
Este cunoscută utilizarea compusului (Z)-1-(2,4-diclorfenil)-5-metil-2-(1H-1,2,4-triazol-1-il)hex-1-en-3-onă în calitate de remediu antifungic către fungiiAlternaria alternataşiFusarium aquaeductuumcare reprezintă agenţi cauzali frecvent întâlniţi la putregaiul de rădăcină [1]. The compound (Z)-1-(2,4-dichlorophenyl)-5-methyl-2-(1H-1,2,4-triazol-1-yl)hex-1-en-3-one is known to be used as an antifungal remedy against the fungi Alternaria alternata and Fusarium aquaeductuum, which are frequently encountered causal agents of root rot [1].
Dezavantajul acestei utilizări constă în aceea că activitatea antifungică nu este la un nivel suficient de înaltă. The disadvantage of this use is that the antifungal activity is not at a sufficiently high level.
Problema rezolvată de invenţie constă în extinderea gamei de utilizări a preparatelor din clasa 1,2,4-triazolilor în agricultură pentru combaterea putregaiului de rădăcină provocat de fungiiF. avenaceumşiF. oxysporum. The problem solved by the invention consists in expanding the range of uses of preparations from the 1,2,4-triazole class in agriculture for combating root rot caused by the fungi F. avenaceum and F. oxysporum.

Izolarea fungilorF. avenaceumşiF. oxysporum- agenţi cauzali ai putregaiului de rădăcină la grâu s-a efectuat în condiţii aseptice pe mediu PDA (Potatoes Dextrosis Agar) (Методы экспериментальной микологии. Киев: Наукова думка, 1982. 550 p.). Acest mediu este unul din cele mai optime medii pentru izolarea, cultivarea şi cercetarea caracterelor morfologo-culturale ale patogenilor menţionaţi. Au fost utilizate fragmente mici de ţesut cu semne de putrefacţie de la baza tulpinii de grâu. Fragmentele au fost aseptizate în soluţie de hipoclorit de calciu de 2% timp de 1-2 min, după care s-au clătit de 2-3 ori în apă distilată, presat între 2 foiţe de hârtie de filtru şi plasat pe mediu în preajma flăcării de gaz. The isolation of the fungi F. avenaceum and F. oxysporum - causal agents of root rot in wheat was carried out under aseptic conditions on PDA (Potatoes Dextrose Agar) medium (Methods of experimental mikology. Kiev: Naukova Dumka, 1982. 550 p.). This medium is one of the most optimal media for the isolation, cultivation and research of the morphological and cultural characteristics of the mentioned pathogens. Small fragments of tissue with signs of rotting from the base of the wheat stem were used. The fragments were asepticized in a 2% calcium hypochlorite solution for 1-2 min, after which they were rinsed 2-3 times in distilled water, pressed between 2 sheets of filter paper and placed on the medium near a gas flame.
Identificarea patogenilor s-a efectuat în baza caracteristicelor macro- şi microscopice conform determinatoarelor (Билай В.И. Фузарии. Киев: Наукова думка, 1977. 422 p.; Barnett H.L., Hunter B.B. Illustrated genera of imperfect fungi, fourth edition. APS Press, 1998, 218 pp). The identification of pathogens was carried out based on macro- and microscopic characteristics according to the determinants (Bilay V.I. Fuzarii. Kiev: Naukova Dumka, 1977. 422 p.; Barnett H.L., Hunter B.B. Illustrated genera of imperfect fungi, fourth edition. APS Press, 1998, 218 pp.).
Compuşii din invenţie şi soluţia cea mai apropiată au fost suplimentaţi la mediul nutritiv PDA în concentraţiile 0,01% (1); 0,005% (2); 0,0025% (3); 0,00125% (4), care s-a aseptizat prin autoclavare la presiunea de 0,5 atm timp de 30 min. Mediul aseptizat, fierbinte s-a turnat în cutii Petri, câte 10 mL în fiecare. După solidificarea mediului, fungii au fost însămânţaţi - câte un disc de PDA cu miceliul fungului, cu diametrul de 4 mm în centrul cutiei Petri. Cutiile cu fungii însămânţaţi, au fost menţinute în termostat la temperatura de 24°C. Înregistrarea diametrului coloniilor (câte 2 diametre perpendiculare, media cărora a servit ca indice biometric) s-a efectuat din ziua 3-4 de la însămânţare, în dependenţă de viteza de creştere a fungilor. Experienţele s-au efectuat în 5 repetiţii. Datele au fost prelucrate statistic în pachetul de soft STATISTICA 7. The compounds of the invention and the closest solution were supplemented to the PDA nutrient medium in concentrations of 0.01% (1); 0.005% (2); 0.0025% (3); 0.00125% (4), which was sterilized by autoclaving at a pressure of 0.5 atm for 30 min. The sterilized, hot medium was poured into Petri dishes, 10 mL each. After the medium solidified, the fungi were seeded - one PDA disk with the fungal mycelium, with a diameter of 4 mm in the center of the Petri dish. The boxes with the seeded fungi were maintained in a thermostat at a temperature of 24°C. The colony diameter was recorded (2 perpendicular diameters, the average of which served as a biometric index) from day 3-4 after seeding, depending on the growth rate of the fungi. The experiments were performed in 5 repetitions. The data were statistically processed in the STATISTICA 7 software package.
