“…M. fructicola is the species most commonly found in Brazilian stone fruits orchards (Fischer et al 2017;Pereira et al 2017). Nevertheless, M. laxa was identified once in an orchard in the state of São Paulo (Angeli et al 2017) and is considered a rare species in the Brazilian territory. This is the first report of the entry of M. laxa in the southern region of Brazil, where much of the peach production is concentrated.…”

“…M. laxa is the most common species in Europe, Chile, South Africa and Iraq, and M. fructigena is found frequently in Europe and Asia (Ogawa et al 1995). M. fructicola and M. laxa are both present in Brazil, but the former is the predominant species (Angeli et al 2017;Fischer et al 2017). These pathogens can cause fruit rot, blossom blight and twig cankers on peach.…”

The Brazilian production of stone fruit is not enough to meet its consumer demand, thus requiring importation of fruit from Spain, Chile, the United States and Argentina. Pathogens that cause brown rot, such as Monilinia spp., can entry the country in asymptomatic fruit as latent infections. The goals of this work were to identify and characterize the species of Monilinia from fruits imported by Brazil, to compare their aggressiveness with Brazilian Monilinia isolates under different conditions and to test their insensitivity to fungicides. It was determined that M. fructicola and M. laxa are entering the country through imported stone fruit. Many isolates have the potential to adapt themselves to the conditions of the main fruit producing regions of Brazil. It was observed that these imported Monilinia isolates showed low sensitivity to the fungicides azoxystrobin, tebuconazole, iprodione and thiophanate-methyl, which are the main fungicides used in the control of brown rot in Brazil. All Monilinia isolates tested were pathogenic to peach. M. fructicola isolates from Chile and US were able to cause disease on apples and pears with and without wound. Our results indicated a high risk of Monilinia spp. entering the Brazilian fruit production.

“…The results obtained in our study are in accordance with this opinion since isolates of M. fructicola developed better at higher temperatures then M. laxa isolates. Detailed studies done by Angeli et al (2017) indicate that M. fructicola is favoured by warmer weather than M. laxa. These authors reported that in Brazil the optimum temperature for development of brown rot caused by M. fructicola was 24.5ºC and for M. laxa was 19.8ºC.…”

“…According to Hrustić et al (2012), heavy rains in the period of flowering, with temperatures ranging from 20 to 25ºС during the day are ideal conditions for the disease development. Angeli et al (2017) cited that there are differences in ecological requirements in areas where these two species co-exist. In these areas, M. fructicola is mostly reported on fruit, whereas M. laxa is mostly prevalent on flowers and twigs (EFSA, 2011).…”

This research was performed to determine the influence of temperature and light conditions to colony growth of Monilinia isolates collected on stone fruits in Montenegro. The fungi cause brown rot on stone fruits and have a great economic impact in Montenegrin stone fruit production. Effects of temperature (at 15°, 22°, 27° and 30˚C) and light (light16h /darkness 8h and constant darkness) were studied on Monilinia laxa (Aderh. & Ruhland) Honey and Monilinia fructicola (G. Wint.) Honey isolates. Optimal temperature for both M. laxa and M. fructicola was 22 °C and at this temperature M. fructicola isolates grew faster than M. laxa. Temperatures higher then optimal favoured M. fructicola, while lower temperature favoured M. laxa. Isolates of both species developed better in darkness while sporulation was instigated by light/dark alteration.

“…According to Casals et al [78], more than 80% of viable conidia of M. fructicola and M. fructigena can germinate at 25 • C and 0.99 a w within 2 h, whereas those of M. laxa require 4 h. The three species can germinate at a temperature range from 0 to 35 • C under 0.99-0.95 a w . The optimum temperatures for M. fructicola and M. laxa were determined at 24.5 and 19.8 • C, respectively [79]. The estimated maximum temperature for lesion development is higher for M. fructicola (30 • C) than for M. laxa (10 • C), inferring that M. fructicola is favored by a warmer weather compared to M. laxa.…”

Peach Brown Rot: Still in Search of an Ideal Management Option

2018

View full text Add to dashboard Cite

Abstract:The peach is one of the most important global tree crops within the economically important Rosaceae family. The crop is threatened by numerous pests and diseases, especially fungal pathogens, in the field, in transit, and in the store. More than 50% of the global post-harvest loss has been ascribed to brown rot disease, especially in peach late-ripening varieties. In recent years, the disease has been so manifest in the orchards that some stone fruits were abandoned before harvest. In Spain, particularly, the disease has been associated with well over 60% of fruit loss after harvest. The most common management options available for the control of this disease involve agronomical, chemical, biological, and physical approaches. However, the effects of biochemical fungicides (biological and conventional fungicides), on the environment, human health, and strain fungicide resistance, tend to revise these control strategies. This review aims to comprehensively compile the information currently available on the species of the fungus Monilinia, which causes brown rot in peach, and the available options to control the disease. The breeding for brown rot-resistant varieties remains an ideal management option for brown rot disease control, considering the uniqueness of its sustainability in the chain of crop production.
