“…The results of the present study revealed that the optimal temperature for M. fructigena and M. fructicola growth was 23ºC, and 28ºC for the M. laxa isolate. These results are partially in agreement with some previous studies (Vasić et al, 2018;Byrde & Willetts, 1977;Pereira et al, 2019;Papavasileiou et al, 2015). Fischer et al (2017) reported that optimal growth rates from 20°C to 25°C, while Papavasileiou et al (2015) found it to be at 25°C, and Lichtemberg et al (2014) at 23.7°C.…”

“…On the other hand, the ability to grow at extreme temperatures revealed some differences in the sensitivity of Monilinia isolates: M. fructigena was the most sensitive, while M. fructicola was the most resistant to extreme temperatures. Pereira et al (2019) reported that minimum temperature averages for development of M. fructicola and M. laxa isolates were 4.5ºC and 4.0ºC, and the maximum temperature average for those isolates was 36ºC, while Papavasileiou et al (2015) showed that 35ºC completely inhibited the growth of tested M. laxa and M. fructicola isolates from Greece.…”

Different brown rot pathogens cause similar symptoms on fruit, which makes it difficult to differentiate them based only on developed symptoms. Therefore, several methods have been described for accurate identification of Monilinia species. In spite of the fact that those methods can be reliable, there are several limitations for their use, and the aim of this study was to find out if there are any specific characteristics that could be used as additional features for precise identification and in-depth characterization of Monilinia species. The results showed that morphological characteristics on PDA, and mycelium growth rate on PDA medium can be useful characters for differentiation of Monilinia species since M. fructicola was found to grow faster than the other two test species, while M. fructigena grew the slowest. MALT was the optimal medium for M. laxa and M. fructigena isolates, while PDA medium was optimal for M. fructicola. Regarding an extremely acidic medium (pH 2), only M. laxa and M. fructicola isolates were able to grow in it, while M. fructigena isolate was the only that grew in a moderately alkaline medium (pH 9). Also, the results revealed that the optimal temperature for M. fructigena and M. fructicola growth was 23oC, while 28oC was optimal for M. laxa isolate. On the other hand, some differences in the sensitivity of Monilinia isolates were revealed at extreme temperatures: M. fructigena isolate was the most sensitive (grew from 4?C to up to 31?C), while M. fructicola isolate was the most resistant (grew at 2?C and 34?C). The obtained results inferred that there are no specific features that can be used for reliable and precise identification of Monilinia species, but we observed some differences regarding the effects of extreme temperatures and pH values of culture medium on different species. Further research, involving more isolates, is needed for a final conclusion. [Project of the Serbian Ministry of Education, Science and Technological Development, Grant no. 451-03-68/2020-14/200214]

“…M. fructicola was originally detected in the nation due to imported stone fruit, and several isolates are able to adapt to the environment of Brazil's primary fruit producing regions. All Monilinia isolates studied were pathogenic to peaches, whereas isolates from Chile and the USA were able to induce brown rot in both wounded and unwounded apples and pears 46 , presenting a high risk of Monilinia spp. in stone fruit production in Brazil.…”

The international trade of plants and their products, such as fresh fruits, can facilitate the introduction and spread of foreign pests and diseases. We examined South Africa’s import of stone fruits (Prunus spp.) as a pathway for introducing Monilinia fructicola (G. Wint.) Honey and document recommended phytosanitary measures to deal with the risk associated with its exportation into the country. Fresh fruits of Prunus spp. are imported from various countries. The current study provides a report on 10 years (2010–2020) importation of Prunus spp. from Spain to South Africa with associated cases of M. fructicola. We also detail the current management measures for imported stone fruits from Spain to South Africa. We report 18 M. fructicola detections that were found during the study period. The number of detections presents enough trends to determine the level of phytosanitary concerns regarding the importation of Prunus spp. fresh fruit from Spain, which cannot be neglected. M. fructicola is an economically important brown rot on many fruit hosts and potentially threatens agricultural and horticultural industries, the environment, and biodiversity in South Africa. The importation of Prunus spp. requires intensive management strategies for M. fructicola, as pathogens may pose a major phytosanitary concern because it could thrive and reproduce in various environmental conditions and on various host plants in South Africa. Therefore, if M. fructicola establishes in South Africa, its impacts will have consequences for different key socioeconomic sectors, including the agricultural industry.

Discontinuance of tebuconazole in the field restores sensitivity of Monilinia fructicola in stone fruit orchards

et al. 2019

Demethylation inhibitor (DMI) fungicides are used to control brown rot in stone fruit worldwide. However, their specific mode of action can select resistant isolates of Monilinia fructicola. Monilinia fructicola resistant to DMI fungicides are associated with a fitness cost in the absence of selective pressure, indicating that the sensitive population can be re‐established when discontinuing the fungicide in the field. This work aimed to build up the sensitive population of M. fructicola after discontinuing the use of tebuconazole for successive crop seasons. The sensitivity of M. fructicola to tebuconazole was assessed in four commercial peach orchards in Paraná and São Paulo States from 2012/13 to 2015/16. Different fungicide programmes were used and DMI fungicides were discontinued from 2013/14. The sensitivity of M. fructicola to tebuconazole was assessed by a mycelial growth assay in vitro and by determining the frequency of the G461S mutation in the MfCYP51 gene. The isolates from Paraná had high sensitivity to the fungicide across all seasons and the frequency of the G461S mutation remained below 5%. The isolates from São Paulo were highly resistant in the 2012/13 season; however, there was a gradual decline until 2015/16. In addition, the G461S mutation frequency in Sao Paulo State was about 80% in the 2012/13 season, but reduced until it was completely undetectable in 2015/16. These results provide evidence that resistance can be managed in orchards with high selective pressure to tebuconazole after discontinuing the use of the fungicide for at least 3 years.
