“…The recommendations for disease control in the country are based on protective treatments with the use of fungicides, especially during flowering and at the pre-harvest (Balardin et al, 1994;Andrade and Matos, 1996). However, this mode of control, besides causing environmental imbalance, raises the cost of production and often does not provide an efficient control due to either the large amount of inoculum that may be present in the orchard, the climatic conditions during the production cycle or the culture management (Balardin et al, 1994).…”

The brown rot caused by Monilinia fructicola is the most important disease in Prunus species in places of hot and humid climate. The development of resistant cultivars is a priority of breeding programs located in humid regions. However, very few sources of good resistance level are known in spite of all the efforts. This work aimed to evaluate the reaction of peach genotypes to M. fructicola. The study was conducted during the 2012/13 season, using a completely randomized design, with two replications of five fruit per plot. Fruit at firm maturation stage (harvest point) of 174 genotypes, including, cultivars, selections and seedlings, were selected for absence of apparent damage and/or infection. These fruits were dipped for 1 min in 70% alcohol, followed by a 5 min immersion in a 0.5% solution of NaClO. After a 10 min rest period they were washed in distilled water and placed in plastic transparent boxes (24.0 x 23.0 x 10.0 cm), lined with moistened filter paper. The inoculation was made, by deposition of a 10µL drop suspension of 25,000 conidia mL-1 of the pathogen using an inoculation syringe. Inoculated fruits were incubated at 25 ± 1°C and 75% relative humidity for 72 hours. After this period, the samples were evaluated for disease incidence (% of diseased fruits) and disease severity (average diameter of lesions and sporulation). The results were compared with the average lesion of cv. 'Bolinha', 0.9 cm (σ=0.9).

“…O fungo M. fructicola tem duas fases de infecção: uma no período de floração, que causa queima de pétalas e cancro nos ramos, e outra nos estágios finais de frutificação, etapa em que ocorre a podridão dos frutos em pré e pós-colheita (HONG et al 1997). As recomendações para o controle da doença no Brasil são baseadas em tratamentos protetores com a utilização de fungicidas, principalmente durante a floração e nos estágios de pré e pós-colheita (BALARDIN et al, 1994;ANDRADE e MATOS, 1996). Este tipo de controle, além de causar desequilíbrio ambiental, eleva o custo de produção e, muitas vezes, não oferece um controle eficiente em função da grande quantidade de inóculo que pode estar presente no pomar, das condições climáticas durante o ciclo produtivo ou do manejo cultural (BALARDIN et al 1994).…”

Stone fruits comprising peach, plum, almond, apricot, cherry and nectarines are attacked by various fungal and prokaryotic (i.e bacteria, fastidious vascular bacteria) pathogens. Amongst fungal diseases, the most important ones are peach leaf curl, brown rot, powdery mildew, rust, leaf spots, peach scab, canker and die-back, black knot, wilt and root rot. Amongst prokaryotic diseases, crown gall, bacterial spot, canker, phony peach, almond leaf scorch and plum leaf scald are important. Stone fruit diseases are successfully managed by the combined use of cultural, chemical and biological measures supplemented with the cultivation of resistant cultivars. Foliar diseases are effectively controlled by timely sprays of fungicides. Proper pruning, applying chemicals and antagonist effectively manage canker and die-back. Removal of severely infested plants and isolation of diseased patches controls wilt, crown and root rot. Crown gall, a very serious disease of stone fruits is being managed successfully by a non-pathogenic strain of the causal bacterium. Diseases caused by fastidious vascular bacteria are managed by applying antibiotics and rouging infested plants.
