“…The results obtained in the present study corroborate with studies carried out by Silva et al (2019) using 5,000 ppm of neem, citronella, lemon balm and melissa of essential oils on the rice seeds of caiapó variety. These studies show that citronella and lemon balm essential oils practically killed the seeds and only 1% of the rice seeds germinated when treated with melissa oil (Silva et al, 2019).…”

“…However, the results with creole corn seeds reported in the present study differ from the studies carried out by Domene et al (2016) with corn seeds of the variety AL Bandeirante, treated with essential oils extracted from leaves of C. citriodora and E. camaldulensis, at a concentration of 3.4 ppm, showed that they did not significantly interfere with germination or seedling length, since they did not differ statistically from the control. Studies performed by Silva et al (2019) showed that the combinations of essential oils of citronella-melissa and citronellamelissa, at 5,000 ppm, inhibited the development of rice seeds, and the combinations neem-melissa and citronella-lemon balm reduced seed germination to 1 and 2%, respectively. These studies show that essential oils can interfere in the physiological quality of different seeds.…”

“…In this sense, studies have shown that essential oils have the potential to be used in the control of diseases that attack crops (Bastos et al, 2004;Silva et al, 2019;Queiroz et al, 2020). The essential oils are products from plant parts (leaves usually) and they are repellent or attractive substances of plants and can have properties mainly of a therapeutic nature.…”

The aim of the present studies was to evaluate the effects of treatments with essential oil emulsion on the sanitary and physiological quality of creole corn seeds. In the studies were evaluated the essential oils of neem (Azadirachta indica), citronella (Cymbopogon nardus), lemon balm (Cymbopogon citratus), melissa (Melissa officinalis L.), and the combinations neem-citronella, neem-lemon balm, neem-melissa, citronella-lemon balm, citronella-melissa and lemon balm-melissa. The tests carried out were germination, length of seedlings (aerial part and root), dry mass and pathology for Fusarium sp. and Aspergillus sp. in seeds of creole corn produced without the use of synthetic pesticides. The studies were carried out in vitro and consisted of the preparation of water emulsion, 5,000 ppm of essential oil and 1% of triton X100 and direct application on the seeds of creole corn, following the protocol of Rules of Seed Analysis (RSA). The results showed a significant decrease in the occurrence of fungi Fusarium sp. and Aspergillus sp. with treatment with essential oils of citronella, lemon balm and melissa, while the oil of neither reduced the occurrence of Fusarium sp., but increased the occurrence of Aspergillus sp. in almost four times. All binary combinations of essential oils reduced the occurrence of both fungi. On the other hand, the physiological quality was strongly affected by the death of creole corn seeds, except for the treatment with lemon balm essential oil. Therefore, these studies allow to affirm that essential oils can be efficient in the control of pathogens, however they can kill the seeds of creole corn.

“…Devido ao crescimento da população brasileira, áreas de cultivo agrícola, principalmente, de pequenos produtores vêm sendo diminuída e inúmeros fatores podem ser citados, dentre eles doenças fúngicas, e o uso de agrotóxicos sintéticos, que vêm ocasionando a redução na produção de alimentos, provocando impactos na agricultura e no meio ambiente. Porém, a demanda de alimentos tem aumentado nos últimos anos requerendo naturalmente um aumento na produtividade do grão (Garcia et al, 2012, Pascuali et al 2018, Silva, et al 2019, Queiroz et al 2020.…”

Estudos têm mostrado que extratos vegetais e os óleos essenciais podem ser uma alternativa em substituição a produtos sintéticos usados no controle de doenças causadas por fungos em diferentes cultivares. Assim sendo, o presente trabalho teve por objetivo avaliar a atividade de inibição de crescimento micelial de óleos essenciais e extratos vegetais sobre os fungos Aspergillus sp e Fusarium sp “in vitro” isolados do feijão-caupi. Foram estudados quatro extratos, hidroalcoólicos e hidroacetônicos, de citronela (Cymbopogon winterianus), capim-cidreira (Cymbopogon citratus), cravo-da-índia (Syzygium aromaticum) e melissa (Melissa officinalis) e a combinação binária entre os mesmos e quatro óleos essenciais citronela (Cymbopogon winterianus), capim-cidreira (Cymbopogon citratus), melissa (Melissa officinalis) e neem (Azadirachta indica A. Juss) e as combinações binárias respectivas. A concentração de óleos essencial usada foi 5.000 ppm, enquanto que, para os extratos foi utilizado 50.000 ppm, em meio BDA (Potato Dextrose Agar). Os resultados mostram que os extratos vegetais e óleos essenciais apresentam atividade antifúngica sobre o crescimento micelial dos patógenos. Contanto, os extratos de cravo-da-índia e citronela e os óleos essenciais de citronela, cidreira e melissa apresentaram os melhores resultados inibindo completamente o crescimento dos fungos. Os óleos essenciais estudados e as combinações binárias inibiram o desenvolvimento dos patógenos, exceto o óleo essencial de neem. Portanto, pode-se inferir que os óleos essenciais e os extratos mostraram-se eficientes e promissores para o desenvolvimento de produtos que possam ser utilizados de forma alternativa na agricultura em substituição aos produtos sintéticos.

The extracts of medicinal plants are used for the treatment of seeds in order to reduce the action of phytopathogens and increase the vigor of the seeds. Currently, computerized image analysis has been used to assess the physiological quality of seed lots. The objective was to evaluate the efficiency of the Vigor-S® software in the evaluation of the physiological quality of cowpea seeds treated with essential oils, comparing with a traditional test and the principal component analysis. Two cowpea cultivars were analyzed, BRS Tumucumaque and BRS Guariba, treated with doses of natural extracts of Alfavaca, garlic, horsetail, citronella and pyroligneous acid. The traditional method consisted of evaluations for germination, first germination count, seedling emergence, emergence speed index, accelerated aging, fresh matter and dry matter of seedling and the image analysis for: seedling length, growth index, uniformity index, vigor index, and germination. A Principal component analysis was applied to reduce the number of variables. Horsetail, Alfavaca and citronella extracts were efficient in increasing the physiological quality of the seeds of at least one cultivar. The Vigor-S® software proved to be efficient compared to traditional tests to assess the physiological quality of seeds. Principal Component Analysis is an ally to identify the best extracts and doses to be used. The image analysis method proved to be effective when compared to the traditional method and can therefore be used.
