Quitosana associada com extratos vegetais no controle pós-colheita de antracnose em mamão ‘formosa’

Abstract: RESUMO O uso excessivo de produtos químicos na cultura do mamão (Carica papaya) coloca em risco a eficácia de fungicidas, em razão dos problemas de resistência dos patógenos a esses produtos, além da possibilidade de resíduos tóxicos colocarem em risco a saúde humana e o ambiente. Diante disto, o presente trabalho teve por objetivo avaliar a eficácia de produtos naturais no controle de Colletotrichum gloeosporioides, in vitro e in vivo. No ensaio in vitro, avaliou-se os extratos aquosos de cravo-da-índia (Syzy… Show more

“…), observaram que hipoclorito de sódio a 1,5% foi efetivo, tanto quanto o fungicida carbendazin, inibindo de 100% do crescimento de Colletotrichum sp. Resultados semelhantes foram observados por Casemiro et al (10) que o fungicida procloraz suprimiu o crescimento micelial de C. gloeosporioides em frutos de mamão, o que corrobora com os resultados de Reis et al (23).…”

“…However, the toxicity of these chemicals and the reported resistance of some microorganisms against pesticides have raised environmental and health concerns among consumers. Many studies have been carried out to find alternative ecofriendly and greener technologies, like, application of essential oils (EO) (Casemiro et al, 2019), plant hormones (Hanif et al, 2020), edible coatings (Vilaplana et al, 2020), use of physical treatments, like, heat treatments (Terao et al, 2019; Vilaplana et al, 2020) and UV irradiation (Vázquez‐Ovando et al, 2018), use of bioagents (Chiquito‐Contreras et al, 2019), biobased and biodegradable packaging (Nilsen‐Nygaard et al, 2021), and so on. Nevertheless, alternative postharvest physical treatments must be capable of triggering the host's (fruit's) defense mechanism and upregulating antimicrobial properties without adverse impact on the fruit quality (Romanazzi et al, 2016).…”

“…Belonging to the family Lauraceae, it is a species with great potential for use as a botanical fungicide, demonstrating its applicability to a high diversity of phytopathogenic fungi. It is an aromatic plant whose main constituents are cinnamaldehyde and eugenol, compounds with antifungal and antibacterial activity (Adarsh et al, 2020; Carmello & Cardoso, 2018; Casemiro et al, 2019; Gomes et al, 2018).…”
