Description
Invenţia se referă la agricultură, şi anume la un procedeu de preparare a soluţiei insecticide pentru tratarea extraradiculară a plantelor împotriva Leptinotarsa decemlineata. The invention relates to agriculture, namely to a process for preparing an insecticidal solution for the extra-radicular treatment of plants against Leptinotarsa decemlineata.
Procedeu de preparare a soluţiei insecticide pentru fortificarea acţiunii acesteia. Process for preparing insecticidal solution to strengthen its action.
Organismele dăunătoare, atacând culturile agricole, provoacă pierderi colosale, ce constituie până la 25…30% din recoltă, iar la dezvoltarea epifită a agenţilor patogeni şi invazia dăunătorilor, recolta este compromisă totalmente [1]. Harmful organisms, attacking agricultural crops, cause colossal losses, which constitute up to 25…30% of the harvest, and with the epiphytic development of pathogens and the invasion of pests, the harvest is completely compromised [1].
Combaterea integrată a dăunătorilor nu exclude utilizarea metodelor chimice. Dacă se utilizează corect, pesticidele sunt foarte eficiente în reducerea populaţiilor dăunătorilor. În ultimul timp a apărut necesitatea utilizării preparatelor mai inofensive, cu doze mai mici ale ingredientelor active pe o unitate de suprafaţă, care influenţează mai puţin asupra mediului ambiant. Pe lângă aceasta, folosirea îndelungată a pesticidelor cu aceeaşi substanţă activă, mai ales în concentraţii mari, poate duce la apariţia unor dăunători rezistenţi faţă de preparatele aplicate [2]. Integrated pest management does not exclude the use of chemical methods. If used correctly, pesticides are very effective in reducing pest populations. Recently, there has been a need to use safer preparations, with lower doses of active ingredients per unit area, which have less impact on the environment. In addition, the long-term use of pesticides with the same active substance, especially in high concentrations, can lead to the emergence of pests resistant to the applied preparations [2].
Procedeul tradiţional de tratare cu insecticide a culturilor pentru combaterea insectelor dăunătoare este bine cunoscut şi include pulverizarea amestecului de apă şi insecticid pe suprafaţa plantelor [3]. The traditional process of treating crops with insecticides to combat harmful insects is well known and includes spraying a mixture of water and insecticide onto the surface of the plants [3].
Însă, conform acestui procedeu, aplicarea dozei recomandate de insecticid conduce la poluarea plantelor, solului, biocenozelor şi pune în pericol sănătatea populaţiei umane. However, according to this procedure, applying the recommended dose of insecticide leads to pollution of plants, soil, biocenoses and endangers the health of the human population.
Pentru a fortifica efectul toxic şi în acelaşi timp a reduce concentraţia insecticidului în soluţia pentru tratarea exraradiculară a plantelor sunt cunoscute diferite procedee. To strengthen the toxic effect and at the same time reduce the concentration of the insecticide in the solution for the extra-radicular treatment of plants, various processes are known.
Este cunoscut procedeul de fortificare a acţiunii toxice a insecticidului Deţis, aplicat la tratarea plantelor, prin adăugarea în soluţia pentru stropit a metil-heptenonului (2-metilhepten-2-on-6) - substanţă care se conţine în uleiurile vegetale şi poate fi extrasă prin metode cunoscute, de exemplu prin purificare cromatografică [4]. The process of strengthening the toxic action of the insecticide Detis, applied to plant treatment, by adding methyl-heptenone (2-methylhepten-2-one-6) to the spraying solution is known - a substance that is contained in vegetable oils and can be extracted by known methods, for example by chromatographic purification [4].
Neajunsul acestui procedeu constă în metodele complicate de obţinere a metil-heptenonului şi date insuficiente despre acţiunea acestuia asupra organismelor vii. The drawback of this process lies in the complicated methods of obtaining methyl-heptenone and insufficient data on its action on living organisms.
În calitate de cea mai apropiată soluţie serveşte procedeul de fortificare a activităţii insecticidului Bidrin (3-dimetoxi-fosfiniloxi-M,M-dimetil-11is-crotonamid sau 3,4,5-trimetilfosnil-g-metilcarbamat) prin adăugarea pentru sinergism a soluţiei de 2-brom-4,5-metilendioxibenzonitril sau 2 -clor-4,5-metilendioxibenzilcianid în proporţie de 1:5 [5]. The closest solution is the process of strengthening the activity of the insecticide Bidrin (3-dimethoxy-phosphinyloxy-M,M-dimethyl-11is-crotonamide or 3,4,5-trimethylphosnyl-g-methylcarbamate) by adding for synergism a solution of 2-bromo-4,5-methylenedioxybenzonitrile or 2-chloro-4,5-methylenedioxybenzylcyanide in a ratio of 1:5 [5].
Neajunsul procedeului dat constă în aceea că pentru sinergism se folosesc substanţe chimice, care sunt periculoase pentru sănătate şi poluează mediul înconjurător. The disadvantage of this process is that for synergism, chemicals are used, which are dangerous to health and pollute the environment.
Problema tehnică pe care o soluţionează prezenta invenţie constă în micşorarea nivelului poluării mediului ambiant şi a produselor agricole prin reducerea conţinutului de insecticid în soluţia pentru tratarea plantelor împotriva dăunătorilor fără diminuarea efectului preparatului. The technical problem solved by the present invention consists in reducing the level of pollution of the environment and agricultural products by reducing the insecticide content in the solution for treating plants against pests without diminishing the effect of the preparation.
Procedeul de preparare a soluţiei insecticide pentru tratarea extraradiculară a plantelor împotriva Leptinotarsa decemlineata include tratarea electrochimică prealabilă a apei în camera catodică a unui electrolizor cu diafragmă la densitatea catodică a curentului de 1,5 A/dm2 până la atingerea pH-ului 9,7…9,9 şi introducerea în apa tratată a imidaclopridului în cantitate de 0,05...0,1 g/L. The process for preparing the insecticide solution for extra-radicular treatment of plants against Leptinotarsa decemlineata includes preliminary electrochemical treatment of water in the cathode chamber of a diaphragm electrolyzer at a cathode current density of 1.5 A/dm2 until reaching pH 9.7...9.9 and introducing imidacloprid into the treated water in an amount of 0.05...0.1 g/L.
Rezultatul tehnic al invenţiei constă în fortificarea acţiunii insecticidului imidacloprid şi micşorarea cantităţii acestuia, astfel asigurând diminuarea pericolului ecologic şi a riscurilor în privinţa sănătăţii populaţiei umane. The technical result of the invention consists in strengthening the action of the insecticide imidacloprid and reducing its quantity, thus ensuring the reduction of the ecological danger and the risks to the health of the human population.
Rezultatul tehnic obţinut se datorează particularităţilor deosebite ale amestecului compus din apă electrochimic activată (catolit) şi insecticid. Se presupune că structura formată din dipolul de apă şi molecula de insecticid are (prin adeziune) o permeabilitate a membranelor celulare sporită, demonstrând astfel efectul de sinergism. The technical result obtained is due to the special characteristics of the mixture composed of electrochemically activated water (catholyte) and insecticide. It is assumed that the structure formed by the water dipole and the insecticide molecule has (through adhesion) an increased permeability of the cell membranes, thus demonstrating the synergistic effect.
Activarea electrolitică a apei este efectuată într-un electrolizor cu anod şi un catod din oţel inoxidabil separaţi printr-o diafragmă inertă (ţesătură Belting). Electrozii sunt amplasaţi pe ambele părţi ale diafragmei la 40 mm. Intensitatea curentului constituie 1,5 A/dm2. Durata ciclului de activare a apei în electrolizor este de 10 min. The electrolytic activation of water is carried out in an electrolyzer with a stainless steel anode and cathode separated by an inert diaphragm (Belting fabric). The electrodes are placed on both sides of the diaphragm at 40 mm. The current intensity is 1.5 A/dm2. The duration of the water activation cycle in the electrolyzer is 10 min.
Exemple de realizare a invenţiei Examples of embodiments of the invention
Exemplul 1 (testarea în laborator) Example 1 (laboratory testing)
Se dizolvă 1 ml de imidacloprid (forma preparativă Midash 200 SL, conţinutul substanţei active de 200 g/L, produsă de Sharda Worldwide Exports Pvt. Ltd India) într-un litru de apă simplă, obţinându-se astfel soluţia de insecticid, cu substanţa activă imidacloprid în cantitate de 0,2 g/L (varianta etalon). Norma recomandată de consum a insecticidului 60,0 g/ha. Pentru variantele experimentale - 1 ml, 0,5 ml şi 0,25 ml de imidacloprid se dizolvă într-un litru de catolit. În soluţiile obţinute se moaie frunze proaspete de cartof, după care ele sunt menţinute timp de 2 ore. În vase separate se plasează (conform schemei experimentului) frunzele prelucrate şi câte 5 larve, vârsta II...III, ale gândacului de Colorado (Leptinotarsa decemlineata) în 4 repetări. În varianta de control frunzele sunt muiate în apă simplă. Dissolve 1 ml of imidacloprid (preparative form Midash 200 SL, active substance content of 200 g/L, produced by Sharda Worldwide Exports Pvt. Ltd India) in one liter of plain water, thus obtaining the insecticide solution, with the active substance imidacloprid in an amount of 0.2 g/L (standard variant). The recommended consumption rate of the insecticide is 60.0 g/ha. For the experimental variants - 1 ml, 0.5 ml and 0.25 ml of imidacloprid are dissolved in one liter of catholyte. Fresh potato leaves are soaked in the obtained solutions, after which they are kept for 2 hours. In separate vessels are placed (according to the experimental scheme) the processed leaves and 5 larvae, age II...III, of the Colorado potato beetle (Leptinotarsa decemlineata) in 4 repetitions. In the control variant, the leaves are soaked in plain water.
S-a evidenţiat că în condiţii de laborator eficacitatea biologică a soluţiei insecticide compuse din catolit şi imidacloprid, în cantitate de 0,2 g/L, împotriva larvelor de Leptinotarsa decemlineata a fost la nivel de etalon, iar la a 3-a zi după prelucrare constituia 100%. Totodată, s-a constatat că la micşorarea cantităţii de imidacloprid în amestec de la 0,2 până la 0,1 şi 0,05 g/L eficacitatea biologică a soluţiei rămâne înaltă constituind 95...100%. Analiza statistică a datelor obţinute demonstrează că utilizarea procedeului de preparare a soluţiei insecticide pentru tratarea plantelor împotriva dăunătorilor permite de a reduce cantitatea de imidacloprid de 2...3 ori, asigurând eficacitatea biologică a preparatului la nivel de etalon (100%). S-a determinat că reducerea dozei de consum a preparatului de 4 ori faţă de normă duce la o scădere nesemnificativă (5%) a eficacităţii biologice a soluţiei obţinute în baza catolitului, demonstrând o pieire de 95% a dăunătorilor (Tab. 1). It was shown that under laboratory conditions the biological efficacy of the insecticidal solution composed of catholyte and imidacloprid, in the amount of 0.2 g/L, against the larvae of Leptinotarsa decemlineata was at the standard level, and on the 3rd day after processing it was 100%. At the same time, it was found that when the amount of imidacloprid in the mixture was reduced from 0.2 to 0.1 and 0.05 g/L, the biological efficacy of the solution remained high, constituting 95...100%. Statistical analysis of the obtained data demonstrates that the use of the process of preparing the insecticidal solution for treating plants against pests allows to reduce the amount of imidacloprid by 2...3 times, ensuring the biological efficacy of the preparation at the standard level (100%). It was determined that reducing the consumption dose of the preparation by 4 times compared to the norm leads to an insignificant decrease (5%) in the biological efficacy of the solution obtained based on the catholyte, demonstrating a 95% destruction of pests (Tab. 1).

Exemplul 2 (testarea în condiţii de câmp) Example 2 (field testing)
Testarea a fost efectuată în patru variante (conform schemei experimentului) şi patru repetări. Fiecare repetare era desfăşurată pe o suprafaţă de 50 m2. Loturile experimentale au fost amplasate după metoda de randomizare. În total în fiecare parcelă au fost câte 240...245 plante de cartof. The testing was carried out in four variants (according to the experimental scheme) and four repetitions. Each repetition was carried out on an area of 50 m2. The experimental plots were placed according to the randomization method. In total, there were 240...245 potato plants in each plot.
Pentru tratarea plantelor a fost pregătită soluţia insecticidă (7,0...7,5 litri pentru fiecare variantă) în felul următor: se dizolvă 10 ml de imidacloprid în 10 litri de apă simplă, obţinând astfel concentraţia soluţiei de lucru a insecticidului de 0,2 g/L (varianta etalon). Pentru variantele experimentale - 10 ml, 5,0 ml şi 2,5 ml de imidacloprid se dizolvă în 10 litri de catolit. Pe parcursul perioadei de vegetaţie au fost efectuate două tratări. Eficacitatea soluţiei insecticide a fost evaluată prin metoda standard la 15 plante din fiecare repetare (adică la 60 plante în fiecare variantă). For the treatment of plants, the insecticide solution was prepared (7.0...7.5 liters for each variant) as follows: 10 ml of imidacloprid was dissolved in 10 liters of plain water, thus obtaining the concentration of the working solution of the insecticide of 0.2 g/L (standard variant). For the experimental variants - 10 ml, 5.0 ml and 2.5 ml of imidacloprid were dissolved in 10 liters of catholyte. Two treatments were carried out during the vegetation period. The effectiveness of the insecticide solution was evaluated by the standard method on 15 plants from each repetition (i.e. on 60 plants in each variant).
În urma testării soluţiei insecticide împotriva larvelor de Leptinotarsa decemlineata în condiţii de câmp s-a constatat că eficacitatea biologică a preparatului este la nivelul etalonului (DEM 0,05 = 0,34), constituind 99,2...100% în dependenţă de concentraţie (Tabelul 2, 3), ce vizibil depăşeşte indicii citaţi în cazul prototipului. S-a constatat că micşorarea conţinutului de insecticid imidacloprid în amestecul propus până la 0,05…0,1 g/L (20,0…30,0 g/ha) asigură diminuarea densităţii populaţiei dăunătorului (la nivel de etalon) şi menţine eficacitatea biologică înaltă împotriva dăunătorului Leptinotarsa decemlineata. After testing the insecticide solution against Leptinotarsa decemlineata larvae in field conditions, it was found that the biological efficacy of the preparation is at the standard level (DEM 0.05 = 0.34), constituting 99.2...100% depending on the concentration (Table 2, 3), which visibly exceeds the indices cited in the case of the prototype. It was found that reducing the content of imidacloprid insecticide in the proposed mixture to 0.05...0.1 g/L (20.0...30.0 g/ha) ensures a decrease in the pest population density (at the standard level) and maintains high biological efficacy against the Leptinotarsa decemlineata pest.

Concluzie: varianta optimă, care a permis obţinerea 100% a eficacităţii biologice, s-a dovedit a fi cea cu reducerea conţinutului de 2 ori a insecticidului (0,1 g/L) în soluţia de stropit. Conclusion: the optimal option, which allowed obtaining 100% biological efficacy, proved to be the one with a 2-fold reduction in the insecticide content (0.1 g/L) in the spraying solution.
Aşadar, tratarea cartofului împotriva dăunătorului Leptinotarsa decemlineata cu soluţie ce conţine apă activată electrochimic (catolit) şi insecticid imidacloprid în concentraţie de 0,05...0,1 g/L (în cantitate de 20,0…30,0 g/ha), adică de 2...3 ori mai mică decât etalonul, menţine eficacitatea biologică a preparatului la nivel de 99,2...100%, asigurând astfel productivitatea scontată a culturii. Therefore, treating potatoes against the pest Leptinotarsa decemlineata with a solution containing electrochemically activated water (catholyte) and the insecticide imidacloprid in a concentration of 0.05...0.1 g/L (in an amount of 20.0...30.0 g/ha), i.e. 2...3 times lower than the standard, maintains the biological efficacy of the preparation at a level of 99.2...100%, thus ensuring the expected productivity of the crop.
