Recently, the Florida strawberry industry faced unprecedented outbreaks of an emerging disease caused by the fungus Neopestalotipsis spp. Currently, there are no fungicides labeled to control this disease in the U.S. and the efficacy of single- and multi-site fungicides is unknown. Therefore, this study aimed to determine the in vitro sensitivity o...

Colletotrichum acutatum is a species complex that causes anthracnose fruit rot (AFR) and root necrosis (ARN) on strawberry. The major and minor species within the complex that affect strawberry production are C. nymphaeae and C. fioriniae, respectively. The disease can significantly reduce yield under conducive weather, and its management has great...

Pestalotiopsis-like species have been reported affecting strawberry worldwide. Recently, severe and unprecedented outbreaks have been reported in Florida commercial fields where leaf, fruit, petiole, crown, and root symptoms were observed, and yield was severely affected. The taxonomic status of the fungus is confusing since it has gone through mul...

Pestalotiopsis spp. have been known to cause strawberry fruit rot. In recent reports from Florida and other strawberry producing areas, the fungus was associated with root and crown rots. The taxonomic status is confusing as two novel genera, Neopestalotiopsis and Pseudopestalotiopsis, have been described. During the 2018-19 season, a severe outbre...

Colletotrichum nymphaeae and C. fioriniae belong to the C. acutatum species complex and cause anthracnose fruit rot (AFR) of strawberry. Quinone-outside inhibitor fungicides were frequently used for AFR management, however resistant populations were recently reported in Florida strawberry fields. Therefore, alternative modes of action, such as the...

Strawberry anthracnose fruit rot and root necrosis, caused by Colletotrichum acutatum, are primary limiting factors in fruit production fields in the United States. Recent research focusing on the phenotypic and genetic characteristics of this species has shed light on the diversity of the C. acutatum species complex. In this study, we performed mu...

Strawberry anthracnose, caused mainly by the Colletotrichum acutatum species complex, is a major disease in strawberry nurseries and production fields. The use of fungicides, such as the quinone outside inhibitors (QoIs), has been extensively deployed for the control of C. acutatum for the past 20 years. C. acutatum resistance to the QoIs was first...

Colletotrichum species cause major diseases of strawberry and disease management depends on the species present. However, species identification based on symptoms and spore morphology is difficult. Therefore, development of molecular techniques for trustworthy and high-throughput identification of Colletotrichum species is vital for the accurate di...

Colletotrichum acutatum sensu latu causes postbloom fruit drop of citrus and anthracnose of strawberries. These diseases are usually widespread within infected fields, although primary conidia (PC) are water dispersed to short distances. C. acutatum produces quiescent infections on citrus and strawberry leaves, which eventually produce secondary co...

Quinone-outside inhibitor (QoI) fungicides are used to manage anthracnose of strawberry, caused by Colletotrichum acutatum. However, selection for resistance to QoI fungicides was first reported in 2013 in Florida, and subsequently in strawberry nurseries and production areas across the USA and Canada. C. acutatum resistance to QoIs is associated w...

Anthracnose fruit rot (AFR) of strawberry, caused by Colletotrichum acutatum, greatly affects production if not controlled. Application of fungicides in addition to the use of less susceptible cultivars are important tools for AFR control. The effects of interrupted wetness duration and inoculum concentration on the development of AFR were evaluate...

Colletotrichum acutatum, the causal agent of anthracnose fruit rot (AFR) and anthracnose root necrosis (ARN), is a major fungal pathogen of strawberry. Control of AFR and ARN has been dependent on the use of Quinone-outside Inhibitor (QoI) fungicides. Resistance of C. acutatum isolates to QoI fungicides was reported for the first time in 2013 in Fl...

Anthracnose fruit rot of strawberry, caused by Colletotrichum acutatum, is a major disease in Florida and frequent quinone-outside inhibitor (QoI) fungicide applications are needed for disease control. From 1994 to 2014, 181 C. acutatum isolates were collected from multiple strawberry fields in Florida with or without QoI spray history. Sensitivity...

Anthracnose Fruit Rot (AFR) of strawberry, caused by Colletotrichum acutatum, is a major disease in Florida and frequent fungicide applications are needed for disease control. Quinone outside inhibitor (QoI) fungicides such as azoxystrobin and pyraclostrobin are commonly used to control AFR. From 1994 to 2014, 177 C. acutatum isolates were collecte...
