Description

Invenţia se referă la agricultură şi chimie, şi anume la un procedeu de tratare a boabelor de grâu comun de toamnă pentru sporirea rezistenţei la acţiunea fungilor F. oxysporum. The invention relates to agriculture and chemistry, namely to a process for treating common winter wheat grains to increase resistance to the action of the fungi F. oxysporum.

Tratarea seminţelor este o metodă de neutralizare a majorităţii agenţilor patogeni (fungici şi bacterieni), dăunătorilor care se răspândesc prin seminţe şi sol. Un astfel de procedeu protejează culturile de daune, contribuind la salvarea a până la 30-50% din recoltă. Productivitatea depinde de metoda de aplicare, calitatea aplicării şi de conţinutul de pesticide de pe suprafaţa seminţelor. În plus, utilizarea preparatelor prin astfel de procedee este mai rentabilă decât pulverizarea ulterioară cu fungicide şi insecticide în timpul creşterii plantelor (Протравливание семян: плюсы и минусы, 22.01.2020, Online, URL: https://lnzweb.com/ru/blog/plyusi-ta-minusi-protruyuvannya-nasinnya). Seed treatment is a method of neutralizing most pathogens (fungal and bacterial), pests that spread through seeds and soil. Such a procedure protects crops from damage, helping to save up to 30-50% of the harvest. Productivity depends on the method of application, the quality of application and the content of pesticides on the surface of the seeds. In addition, the use of preparations by such procedures is more cost-effective than subsequent spraying with fungicides and insecticides during plant growth (Протравливание семян: плюсы и минусы, 22.01.2020, Online, URL: https://lnzweb.com/ru/blog/plyusi-ta-minusi-protruyuvannya-nasinnya).

Calitatea seminţei/bobului, o componentă importantă a industriei agricole şi, totodată, fundamentul succesului programelor de implementare a noilor soiuri şi de producere a culturilor, este determinată de diferiţi factori, dintre care vigoarea seminţei/bobului este cea mai importantă însuşire, deoarece conferă plantelor o capacitate inerentă creşterii în condiţii favorabile şi nefavorabile (Filho J.M. Seed vigor testing: an overview of the past, present and future perspective. Sci. agric. (Piracicaba, Braz.), 2015, v. 72, nr. 4, Online, URL: https://www.scielo.br/j/sa/a/TCgVpMYmRWtGn6dQSSsQVbJ/?lang=en). În condiţile Republicii Moldova putregaiul de rădăcină la grâul comun de toamnă este cauzat de o multitudine de fungi, printre care Fusarium oxysporum se remarcă prin incidenţă şi virulenţă sporită. Patogenul contribuie în mare măsură la diminuarea germinaţiei boabelor şi creşterii plantelor, ceea ce se reflectă asupra diminării vigorii plantelor. Seed/grain quality, an important component of the agricultural industry and, at the same time, the foundation of the success of new variety implementation and crop production programs, is determined by various factors, of which seed/grain vigor is the most important characteristic, as it gives plants an inherent capacity to grow in favorable and unfavorable conditions (Filho J.M. Seed vigor testing: an overview of the past, present and future perspective. Sci. agric. (Piracicaba, Braz.), 2015, v. 72, no. 4, Online, URL: https://www.scielo.br/j/sa/a/TCgVpMYmRWtGn6dQSSsQVbJ/?lang=en). In the conditions of the Republic of Moldova, root rot in common winter wheat is caused by a multitude of fungi, among which Fusarium oxysporum stands out for its increased incidence and virulence. The pathogen contributes greatly to the reduction of grain germination and plant growth, which is reflected in the reduction of plant vigor.

Testul "Vigoarea seminţelor/plantelor" este utilizat cu succes în diferite scopuri, inclusiv la stabilirea influenţei patogenilor Fusarium spp. asupra boabelor de grâu (Hassani F., Zare L., Khaledi N. Evaluation of germination and vigor indices associated with Fusarium-infected seeds in pre-basic seeds wheat fields. Journal of Plant Protection Research, 2019, 59(1), p. 69-85). The "Seed/Plant Vigor" test is successfully used for various purposes, including determining the influence of Fusarium spp. pathogens on wheat grains (Hassani F., Zare L., Khaledi N. Evaluation of germination and vigor indices associated with Fusarium-infected seeds in pre-basic seeds wheat fields. Journal of Plant Protection Research, 2019, 59(1), p. 69-85).

În legătură cu cele menţionate, este deosebit de important de a identifica procedee de tartare, care ar utiliza compuşi cu capacitate de sporire a vigorii boabelor de grâu la acţiunea fungilor Fusarium. In connection with the above, it is particularly important to identify tartarization processes that would use compounds capable of increasing the vigor of wheat grains to the action of Fusarium fungi.

Este cunoscut un procedeu de protecţie al plantelor de acţiunea nocivă a fungilor fitopatogeni cu utilizarea compusului (E)-1-(2,4-diclorofenil)-4,4-dimetil-2-(1H-1,2,4-triazol-1-il)pent-1-en-3-ol (Diniconazol) [1]. Dezavantajul constă în aceea că procedeul nu conduce la o protecţie antifungică suficient de înaltă faţă de fungii F. oxysporum. A method of protecting plants from the harmful effects of phytopathogenic fungi is known using the compound (E)-1-(2,4-dichlorophenyl)-4,4-dimethyl-2-(1H-1,2,4-triazol-1-yl)pent-1-en-3-ol (Diniconazole) [1]. The disadvantage is that the method does not lead to a sufficiently high antifungal protection against the fungus F. oxysporum.

Problema rezolvată de invenţie constă în extinderea gamei de procedee de tratare a boabelor de grâu comun de toamnă cu compuşi din clasa 1,2,4-triazolilor care să asigure sporirea rezistenţei plantelor de grâu la acţiunea fungilor F. oxysporum. The problem solved by the invention consists in expanding the range of procedures for treating common winter wheat grains with compounds from the 1,2,4-triazole class to ensure increased resistance of wheat plants to the action of the F. oxysporum fungi.

Procedeul, conform invenţiei, constă în tratarea boabelor de grâu comun de toamnă cu soluţie apoasă a compusului (Z)-4,4-dimetil-1-(2,4-diclorfenil)-2-(1H-1,2,4-triazol-1-il)pent-1-en-3-onă cu formula: The process, according to the invention, consists of treating common winter wheat grains with an aqueous solution of the compound (Z)-4,4-dimethyl-1-(2,4-dichlorophenyl)-2-(1H-1,2,4-triazol-1-yl)pent-1-en-3-one with the formula:

, ,

în concentraţie de 0,005-0,01%, timp de 3 ore. in a concentration of 0.005-0.01%, for 3 hours.

Avantajul invenţiei constă în aceea că utilizarea în procedeul revendicat a compusului (Z)-4,4-dimetil-1-(2,4-diclorfenil)-2-(1H-1,2,4-triazol-1-il)pent-1-en-3-onă contribuie la sporirea rezistenţei plantelor de grâu la acţiunea F. oxysporum în raport cu soluţia cea mai apropiată. The advantage of the invention lies in the fact that the use in the claimed process of the compound (Z)-4,4-dimethyl-1-(2,4-dichlorophenyl)-2-(1H-1,2,4-triazol-1-yl)pent-1-en-3-one contributes to increasing the resistance of wheat plants to the action of F. oxysporum in relation to the closest solution.

De asemenea, compusul din invenţie are un preţ de cost redus faţă de cel din cadrul soluţiei celei mai apropiate, deoarece sinteza lui se desfăşoară într-o singură etapă faţă de 3 etape din cadrul celei mai apropiate solutii şi constă în utilizarea cetonei 3,3-dimetil-1-(1H-1,2,4-triazol-1-il)butan-2-ona obţinute conform brevetului MD 4505 B1 2017.08.31. Also, the compound of the invention has a reduced cost compared to that of the closest solution, because its synthesis takes place in a single step compared to 3 steps in the closest solution and consists of using the ketone 3,3-dimethyl-1-(1H-1,2,4-triazol-1-yl)butan-2-one obtained according to patent MD 4505 B1 2017.08.31.

Rezultatul tehnic al invenţiei constă în sporirea indicelui de vigoare cu 30,1-228,49% în comparaţie cu cea mai apropiată soluţie. The technical result of the invention consists in increasing the vigor index by 30.1-228.49% compared to the closest solution.

În calitate de material pentru cercetare au servit: 1) boabe de grâu comun de toamnă a genotipului L M/M3; 2) filtratul de cultură (FC) al fungilor Fusarium oxysporum; 3) derivaţii vinil-triazolici: (Z)-4,4-dimetil-1-(2,4-diclorfenil)-2-(1H-1,2,4-triazol-1-il)pent-1-en-3-onă - (invenţia) şi (E)-1-(2,4-diclorfenil)-4,4-dimetil-2-(1H-1,2,4-triazol-1-il)pent-1-en-3-ol (Diniconazol) - (soluţia cea mai apropiată), în concentraţii de 0,005% şi 0,01%. FC F. oxysporum a fost pregătit prin inocularea miceliului fungic la mediul nutritiv lichid Cszapek, conform compoziţiei descrise în (Tuite J. Plant Pathological methods (Fungi and Bacteria). Burgess Publishing Company, Minneapolis, 1969, 239 p.). The following materials were used for the research: 1) grains of common winter wheat of the L M/M3 genotype; 2) culture filtrate (FC) of the fungus Fusarium oxysporum; 3) vinyl-triazole derivatives: (Z)-4,4-dimethyl-1-(2,4-dichlorophenyl)-2-(1H-1,2,4-triazol-1-yl)pent-1-en-3-one - (invention) and (E)-1-(2,4-dichlorophenyl)-4,4-dimethyl-2-(1H-1,2,4-triazol-1-yl)pent-1-en-3-ol (Diniconazole) - (closest solution), in concentrations of 0.005% and 0.01%. FC F. oxysporum was prepared by inoculating fungal mycelium to Cszapek liquid nutrient medium, according to the composition described in (Tuite J. Plant Pathological methods (Fungi and Bacteria). Burgess Publishing Company, Minneapolis, 1969, 239 p.).

Boabele de grâu bine selectate în baza uniformităţii şi mărimii au fost tratate timp de 3 ore cu soluţii apoase de (Z)-4,4-dimetil-1-(2,4-diclorfenil)-2-(1H-1,2,4-triazol-1-il)pent-1-en-3-onă şi a analogului proxim (E)-1-(2,4-diclorfenil)-4,4-dimetil-2-(1H-1,2,4-triazol-1-i)pent-1-en-3-ol în concentraţii de 0,005% şi 0,01%, după care s-au uscat în aer liber la temperatură de cameră, timp de 48 ore. Ulterior boabele au fost menţinute pentru 18 ore în FC F. oxysporum, apoi clătite cu apă distilată şi plasate în cutii Petri între 2 foiţe de hârtie de filtru umectată cu apă distilată şi menţinute la temperatura de 19-20ºC timp de 6 zile. Wheat grains well selected based on uniformity and size were treated for 3 hours with aqueous solutions of (Z)-4,4-dimethyl-1-(2,4-dichlorophenyl)-2-(1H-1,2,4-triazol-1-yl)pent-1-en-3-one and the close analogue (E)-1-(2,4-dichlorophenyl)-4,4-dimethyl-2-(1H-1,2,4-triazol-1-yl)pent-1-en-3-ol in concentrations of 0.005% and 0.01%, after which they were dried in the open air at room temperature for 48 hours. Subsequently, the grains were maintained for 18 hours in FC F. oxysporum, then rinsed with distilled water and placed in Petri dishes between 2 sheets of filter paper moistened with distilled water and maintained at a temperature of 19-20ºC for 6 days.

Emulsiile preparatelor au fost obţinute prin adăugare de dimetilsulfoxid de 9%, emulgator TWIN-80 de 20% şi etanol de 70% la compusul din invenţie şi cel din cadrul soluţiei apropiate, luaţi în concentraţie de 1%. The emulsions of the preparations were obtained by adding 9% dimethyl sulfoxide, 20% TWIN-80 emulsifier and 70% ethanol to the compound of the invention and that of the related solution, taken in a concentration of 1%.

În calitate de martor I au servit boabele muiate timp de 18 ore în apă distilată, iar martor II - boabele muiate timp de 18 ore în FC F. oxysporum. As control I, they served the grains soaked for 18 hours in distilled water, and as control II, the grains soaked for 18 hours in FC F. oxysporum.

Experienţa a fost efectuată în 3 repetiţii, câte 30 de boabe în fiecare. În calitate de criteriu al rezistenţei/sensibilităţii la patogen a servit vigoarea boabelor, stabilită în baza produsului germinaţie, % x lungimea plantulei, cm (Pradeep. Seed quality parameters (Germination percentage and seedling vigor index) of rabi sorghum seeds influenced by tice weevil infestation. MOJ Toxicol., 2018, 4, p. 391-396.) Datele au fost prelucrate statistic în pachetul de soft STATISTICA 8. The experiment was carried out in 3 repetitions, 30 grains each. Grain vigor, established on the basis of the germination product, % x seedling length, cm, served as a criterion for resistance/susceptibility to the pathogen (Pradeep. Seed quality parameters (Germination percentage and seedling vigor index) of rabi sorghum seeds influenced by tice weevil infestation. MOJ Toxicol., 2018, 4, p. 391-396.) The data were statistically processed in the STATISTICA 8 software package.

Datele prezentate în Tabel relevă că indicele de vigoare a boabelor în varianta cu FC F. oxysporum a fost mult mai mic (cu 55,63%) în comparaţie cu Martorul I, astfel demonstrându-se influenţa negativă puternică a ciupercii asupra vigorii boabelor de grâu. The data presented in the Table reveal that the grain vigor index in the variant with FC F. oxysporum was much lower (by 55.63%) compared to Control I, thus demonstrating the strong negative influence of the fungus on the vigor of wheat grains.
