“…In fruit plants, attacks by Colletotrichum species have been reported in tree tomato (Solanum betaceum) [21,28,56,65,66], mango (Mangifera indica) [21,28,67], Passiflora (Passiflora edulis) [21,29], strawberry (Fragaria × ananassa) [44,47], blackberry (Rubus glaucus) [23,[30][31][32], plantain (Musa spp.) [36], soursop (Annona muricata) [22,45], avocado (Persea americana) [39,40,43] Tahiti lima (Citrus latifolia) [41,68,69], papaya (Carica papaya) [70], and grape (Vitis vinifera) crops [38].…”

Colletotrichum Species Complexes Associated with Crops in Northern South America: A Review

et al. 2022

Colletotrichum genus comprises a high number of plant pathogens causing anthracnose disease in different tropical and non-tropical crops. We aimed to review northern South American studies in the online SCOPUS database to: create a taxonomically updated list of the species complexes found in the region, describe their most important phytopathological characteristics, revise the methods used in the region to control disease, and discuss the role of fungus as a plant endophyte. A total of 19 Colletotrichum species within five complexes—acutatum, boninense, gigasporum, gloeosporioides, and orbiculare—have been reported in northern South America. Few studies have been conducted, particularly in Peru and Ecuador, despite the diversity of Colletotrichum hosts cultivated in the region. Important information can be extracted from our review: species do not appear to show host specificity, although some isolates show host preferences, certain plant species can host several Colletotrichum species, some studies show the importance of using plant extracts to control the disease, but biological control using microorganisms is certainly an open area of research in the region. In northern South America, only a few hosts have been reported to harbor Colletotrichum as endophyte, and the potential of these endophytes as biological control agents has not yet been explored.

“…Typically, Colletotrichum gloeosporioides (Penz.) Sacc is a causative agent for anthracnose disease which directly reduces mango fruit quality and quantity, in which the disease incidence can reach up to 100% (Santiago et al, 2006;Martinez et al, 2020). The post-harvest phase is the most damaging and economically significant phase of the disease worldwide (Akem, 2006).…”

Anthracnose is the major pre- and postharvest disease of mango which caused by Colletotrichum gloeosporioides. In-vitro and in-vivo studies were done to evaluate the antifungal activity of Pennisetum purpureum weed extract on control of C. gloeosporioides. Result: The in-vitro result showed that methanol crude extract of P. purpureum exhibited the best antifungal activity against C. gloeosprioides with an average minimum inhibition concentration value of 3.13 mg/ml and it had the highest total activity (5.28 ml/g) on inhibition of C. gloeosprioides. Meanwhile, the in-vivo result demonstrated that the fruits coated with alginate incorporated crude extract at a concentration of 18 mg/ml were most effective in retaining fruit firmness and had the smallest size lesion in diameter (0.34 cm) as compared to other treatments. The phytochemical assay of methanolic crude extract revealed the presence of phenolic compound (tannins), alkaloids and flavonoids but steroids, saponin, amino acid and oil were absent. Conclusion: This study has demonstrated that alginate based coating incorporated with methanolic crude extract of P. purpureum could be used to inhibit anthracnose pathogen of C. gloeosporioides, thereby extending the shelf life of mango fruits. Keywords: anthracnose, coating, compound, plant extract, mango

“…Para o controle da doença são recomendadas práticas culturais como o uso de sementes certificadas, plantio menos adensado, eliminação de restos de cultura, rotação de cultura com espécie de planta não hospedeira do fungo (Ali, Bordoh, Singh, Siddiqui, & Droby, 2016) além do controle químico com produtos registrados no Ministério de Agricultura Pecuária e Abastecimento (MAPA, 2021), uma vez que não existem cultivares resistentes disponíveis. O uso consecutivo de produtos com o mesmo mecanismo de ação aliado ao uso indiscriminado de fungicidas oferece risco a saúde e danos ao ambiente além da seleção de variantes resistentes aos princípios ativos utilizados (Tyskiewicz et al, 2019;Martinez, Gomez, Ramirez, Gil, & Durango, 2020).…”

Produtos naturais no controle de Colletotrichum sp. associado a pimenta-de-cheiro (Capsicum chinense Jacq.)

2021

View full text Add to dashboard Cite

A pimenta-de-cheiro (Capsicum chinense Jacq.) é uma hortaliça muito consumida no Estado do Amazonas, cultivada principalmente por pequenos produtores. A expansão da cultura é fortemente afeta pela ocorrência da antracnose, doença causada pelo fungo Colletotrichum sp., sendo o principal problema fitossanitário na cultura na região, podendo alcançar 100% de incidência. O controle é feito por meio de práticas culturais e uso de fungicidas. Este trabalho teve como objetivo avaliar o potencial do extrato aquoso de três espécies vegetais, Curcuma longa, Croton cajucara e Piper marginatum no desenvolvimento de Colletotrichum sp. in vitro, e na redução da incidência da doença em frutos de pimenta-de-cheiro. Foram utilizados os extratos aquosos obtidos a frio e a quente de cada espécie vegetal, para avaliar o crescimento micelial e a produção de conídio em meio de cultura BDA. O efeito dos extratos na redução da incidência da doença foi avaliado em frutos destacados, pulverizados com os extratos antes e após a inoculação com o fitopatógeno. Não foi observado efeito dos extratos no crescimento micelial e na esporulação do fungo em meio de cultura. Em frutos destacados houve redução da incidência da doença, quando os extratos foram aplicados de forma preventiva, podendo ter potencial para uso como uma medida complementar para o manejo da doença.
