“…Colletotrichum nymphaeae has become a serious problem, threatening strawberry industry in Iran, since its first outbreak in 2013 (Karimi et al, 2017). Different conventional methods, including chemical fungicides, crop sanitation, cultural methods, and resistant cultivars, are used to control the disease (Smith, 2013). It was originally assumed that the primary infection in strawberry fields starts from infected plants growing near the strawberry field (Smith, 2013), since most of the Colletotrichum spp.…”

Strawberry anthracnose caused by Colletotrichum spp. is considered one of the most serious and destructive disease of strawberry worldwide. Weeds, as possible hosts of the pathogen, could have a role as potential inoculum reservoir. To prove this hypothesis, symptomless weeds were collected in strawberry fields showing anthracnose symptoms in Iran. Ten isolates with Colletotrichum -like colonies were recovered from symptomless Amaranthus viridis L., Convolvulus arvensis L., Fumaria officinalis L., Lactuca serriola L., and Sonchus oleraceus L. plants. The isolates were identified as C. nymphaeae , based on a combination of morphological and sequence data of TUB and GADPH genes. This identification was further validated using Rep-PCR fingerprinting analysis, which produces species-specific DNA fingerprints and unveils inter and intra variation of the species examined in this study. Moreover, rep-PCR marker was used to reveal accurate taxonomic position of Colletorichum spp. causing strawberry anthracnose belonging to the C. acutatum complex, including C. acutatum sensu stricto, C. fiorinae, C. godetiae, C. nymphaeae, C. salicis , and C. simmondsii . The C. nymphaeae isolates originating from symptomless weeds confirmed their pathogenicity on detached strawberry, proving that weeds in strawberry field may have a role as reservoir of inoculum. However, further studies are necessary to quantify their actual contribution to anthracnose epidemics in strawberry fields.

Anthracnose caused by <i>Colletotrichum</i> spp. is a major disease of strawberry plants worldwide. The anthracnose of strawberries in Korea has occurred in most cultivated strawberry varieties since its first report in 1990. Although many studies and efforts have been made to control the disease, anthracnose continues to affect strawberry yields in Korea. In this review, we introduced various management methods to control anthracnose in strawberries, such as identifying pathogens and environmental factors involved in this disease, understanding the importance of latent infection, and developing diagnostic techniques and control methods. Through this review, we propose that researchers can elucidate a comprehensive and practical approach to control anthracnose by understanding this disease and developing strategies to prevent its spread, ultimately benefiting strawberry farmers.

Potencial de óleos essenciais no controle de fungos fitopatogênicos em pós-colheita de morango

RESUMOA cultura do morango é de grande importância no contexto agrícola mundial, com uma produção anual que supera 4,5 milhões de toneladas. Porém, as características desta fruta a tornam altamente susceptível a fatores físicos e biológicos de deterioração, tornando-a altamente perecível e acarretando altos níveis de perdas no campo e na pós-colheita. Dentre os fatores biológicos tem destaque a ação de fungos fitopatogênicos, dentre os quais o Botrytis cinerea e o Colletotrichum gloeosporioides tem papel principal. Dentre as alternativas naturais para controle destes fitopatógenos, os óleos essenciais de plantas medicinais e aromáticas vêm sendo investigados. Neste contexto, no presente trabalho a atividade antifúngica de óleos essenciais de nove espécies de Citrus e de Cymbopogon citratus foi avaliada in vitro contra B. cinerea e C. gloeosporioides. Os óleos de Citrus sinensis e C. citratus foram os mais ativos in vitro (MIC -0,25 e 0,06 mg.mL -1 , respectivamente) e, portanto, selecionados para os ensaios com morangos in natura, visando manter sua qualidade pós-colheita. Os ensaios foram conduzidos sob duas condições ambientais, ou seja, sob condições ambiente de armazenamento (25 ºC) e em armazenamento refrigerado (10 ºC). Aplicados na concentração 1,0 mg.mL -1 , o óleo essencial de C. sinensis mostrou-se mais eficaz sob condições ambiente de armazenamento, e a mistura dos dois óleos em partes iguais em armazenamento refrigerado. Em ambas as condições, melhores resultados foram obtidos através da aplicação por contato direto. Os óleos essenciais foram ainda incorporados a um filme de revestimento composto por matriz de metil-celulose e testados in vitro quanto ao seu potencial de inibição de B. cinerea. Nestas condições, o óleo essencial de C. sinensis mostrou-se o mais eficiente.Através dos resultados foi possível concluir que os óleos essenciais são uma opção viável para o controle de fitopatógenos em morango e para manutenção de sua qualidade pós-colheita.
