“…Embora grande parte resultados sejam promissores, aprimorar a quantificação da composição e a compreender os mecanismos de ação antimicrobiana dos óleos são cruciais no desenvolvimento de formulações comerciais (GEROMINI et al, 2012;CARVALHO et al, 2014;ALMEIDA, 2015). Para Nascimento et al (2021), outra questão prioritária para ampliação do uso desses fitoterápicos é a definição de dosagens e contornar a instabilidade química desses compostos.…”

A presente revisão de literatura teve como objetivo elucidar os principais métodos de tratamentos de sementes de café arábica que possam auxiliar na manutenção da qualidade fitossanitária e fisiológica, bem como na longevidade das sementes de café durante o período de armazenamento. O conteúdo foi analisado de forma qualitativa e exploratória em materiais científicos publicados entre 1990 e 2023, com ênfase aos materiais publicados nos últimos 10 anos. As buscas foram realizadas utilizando palavras chaves como: "tratamento de sementes de café”, “produção de sementes de café”, “sementes de café”, “qualidade de sementes de café”, “alternativas para tratamento de sementes de café” redigidos em português e em inglês. Ressalta-se que as publicações também foram avaliadas com base na relevância de informações, data de publicação, objetivo do trabalho, com a finalidade de encontrar as publicações com maiores similaridades com o tema.

“…Wakil and Ghonim, 2000;Helmy et al, 2001;Mueller et al, 2002;Shaat and El-Argawy, 2011). Use of fungicides and biocontrol agents (especially Trichoderma species) significantly inhibited the disease Sclerotinia stem rot of soybean caused by S. sclerotiorum (Sumida et al, 2015), fluazinam inhibited 100% of the S. sclerotiorum followed by thiophanate-methyl (Costa and da Silva Costa, 2004), fluazinam and procymidone inhibited the S. sclerotiorum in common bean (Vieira et al, 2012;Reis et al, 2010), different fungicides have a different mechanism of action to inhibit the pathogen like procymidone retard the spore germination of S. sclerotiorum (Picinini and Goulart, 2002). Application time of fungicide is a critical factor that reduces the disease incidence and increases the yield (Mueller et al, 2004).…”

Sclerotinia trifoliorum, the fungal plant pathogen first reported in 2021 from Pakistan on Trifolium alexandrinum L. (Egyptian clover; an annual winter fodder crop), causing Stem and crown rot disease. About 46% to 55% incidence of this disease was recorded on E. clover cultivated in the irrigated tract of the country in 2018-19. This disease is subjecting significant crop losses and drastically reducing growth. An integrated disease management approach employing biological and chemical control was adopted to manage this wide-spreading fungal pathogen. The fungal antagonists, including Trichoderma harzianum, T. longibrachiatum, and T. asperellum Moreover, fungicides, including Thiophanate Methyl, Tebuconazole, Tubeconazole+Emdachloprid, Chlorothalonil+cymoxanil, Azoxystrobin, Pyraclostrobin+Metiram, and Mancozeb+Metalaxyl were tested under in vitro and field conditions. Among Trichoderma species, the best response was achieved by T. harzianum with 80.61% inhibition compared to control. Among concentrations of T. harzianum, the best response was achieved on 1/10 (1.24 cm) with 2.4 average No. of Sclerotia and 66% inhibition. Under filed condition experiments, the data regarding Disease severity in T. harzianum treated trays was 51.7% compared to untreated/control 73.5%. Besides disease control, the application of T. harzianum showed a significant increase in green and dry fodder weight (851 grams with 87 grams of dry weight) than untreated/control (561 grams with 55 grams of dry weight) in the fourth cut. For chemical evaluation, seven fungicides tested at three concentrations under in vitro trials among these Thiophanate methyl (0.5 cm) with 90.7% inhibition were found more effective. Thiophanate Methyl's application significantly reduced the disease severity compared to control plants with disease severity in fungicide-treated trays was 28.7% compared to untreated/control 73.5% and significant increase green and dry fodder weight (931 grams with 92 grams of dry weight) than untreated/control (561 grams with 55 grams of dry weight) in the fourth cut.

“…No entanto, com o avanço da agricultura sustentável e a maior conscientização sobre os efeitos negativos ao meio ambiente e ao ser humano causados pelo uso indiscriminado de defensivos agrícolas, além do custo elevado desses produtos, tem-se intensificado a busca por métodos alternativos para o controle de fitopatógenos (Oaya et al, 2019). É almejado que estes métodos alternativos sejam biodegradáveis, ecologicamente corretos, baratos e seguros (Nascimento et al, 2021).…”

The objective of this work was to evaluate the effect of Eucalyptus globulus essential oil on the health and physiological quality of seeds of Mimosa caesalpiniifolia Benth. and the transmission of Fusarium sp. associated with seeds. The seeds were immersed in four concentrations of E. globulus essential oil (0.25%; 0.50%; 0.75% and 1.0%). The seeds were also treated with Captana fungicide (240g for 100 kg of seeds) and immersed in sterile distilled water (control). After being treated, the seeds were evaluated by the health test, using the filter paper method (blotter test) and by the physiological quality through germination, first count, germination speed index and seedling length. The transmission of Fusarium sp. via seeds was also assessed, as it is considered potentially pathogenic. The identified fungi were: Cladosporium sp. (16.5%), Aspergillus sp. (15.5%), Fusarium sp. (7.5%), Penicillium sp. (4.0%), Rhizopus sp. (2.5%) and Periconia sp. (0.5%). The essential oil of E. globulus, in any concentration, reduced efficiently the incidence of fungi associated with M. caesalpiniifolia seeds and did not affect the physiological quality of the treated seeds. Fusarium sp. was transmitted via seeds and caused root rot and hypocotyl necrosis.
