“…Temperature and wetness duration have been reported as the two most important abiotic factors influencing conidial germination (Casals et al, 2010, Xu et al, 2001, fruit infection (Biggs and Northover, 1988, Phillips, 1984, Corbin, 1962, rot development and sporulation (Bannon et al, 2008, Gell et al, 2008. Although many studies have been carried out to determine the effect of temperature on brown rot infection, colonization, and sporulation on stone fruits, the effect is usually studied within a narrow range of temperature and with only a single species included in a given study.…”

Brown rot on peaches and nectarines caused by Monilinia spp. results in significant economic losses in Europe. Experiments were conducted to study the effects of temperature (0-33 °C) on the temporal dynamics of decay and mycelium development and the subsequent sporulation on peaches and nectarine fruit infected by M. laxa and M. fructicola. The rates of decay and mycelium development increased with temperature from 0 °C to 25 °C for both Monilinia species. At 0 °C, decay was faster for M. laxa (0.20 cm days) than for M. fructicola (0.07 cm days); indeed, M. laxa was able to develop mycelia and sporodochia, but M. fructicola was not. At 4 and 20 °C, there were no differences in decay and mycelia development between the two Monilinia species. When temperature increased from 25 to 33 °C, the rates of fungal decay and mycelium development decreased. At 30 and 33 °C, M. fructicola decayed faster (0.94 and 1.2 cm days, respectively) than M. laxa (0.78 and 0.74 cm days, respectively) and could develop mycelia and produce sporodochia, whereas M. laxa failed at 33 °C. These results indicated that M. fructicola is better adapted to high temperatures, whereas M. laxa is better adapted to low temperatures. These results can be used to predict the relative importance of the two species during the season at a given site and to improve management strategies for brown rot in areas where both species are present.

“…This paradox suggests that conidial viability could be longlasting in the field and/or sufficient moisture exists at the infection site (Holb 2008). Positive relationships between T, wind speed, and the density of airborne conidia have also been reported (Bannon et al 2009). …”

“…at any stage of its development, but the disease only becomes severe when the fruit begins to ripen (Xu et al 2007;Gell et al 2008;Villarino et al 2011). Brown rot is spread by the dispersal of Monilinia conidia, which can occur by wind, water, insects, birds, and man (Byrde and Willetts 1977), and the survival, colonization, latency, reproduction, release, transport, and deposition of Monilinia conidia are related to the environmental temperature (T), the relative humidity (RH), the amount of rainfall, and the wind direction (Corbin et al 1968;Bannon et al 2009). …”

“…Previous studies showed that viability of trapped conidia was 60 % (Holb, 2008b). Relative humidity, mean temperature, and wind were shown to be important in explaining the variation in hourly spore counts of M. fructigena conidia (Holb, 2008b;Bannon et al, 2009).…”

In a two-year Hungarian study, spore dispersal diurnal periodicity and viability of Monilinia spp. and their relation to weather components were determined in an organic apple orchard. Conidia of Monilinia spp. were first trapped in late May in both years. Low number of conidia were trapped until end-June. Thereafter, number of conidia continuously increased until harvest. Conidia in a 24-h period showed diurnal periodicity pattern, with th highest concentration in the afternoon hours. Spore viability with FDA staining showed that viability ofconidia ranged from 45 to 70% with showing lower viability in the dry than in the wet days in both years. Temperature and relative humidity correlated positively with mean hourly conidia numbers in both years. Mean hourly rainfall was negatively but poorly correlated with conidiacatches in both years. Results were compared and discussed with previous observations.
