E-mail: [email protected]. Corresponding author. ABSTRACT: Brown rot is the most important disease of peaches in Brazil. The objective of this study was to compare the brown rot monocyclic components from Monilinia fructicola and M. laxa isolates from Brazil on peaches, due to the detection of M. laxa in the São Paulo production area. Conidia germination and pathogen sporulation were assessed in vitro under a temperature range of 5-35oC and wetness duration of 6-48h. Incubation and latent periods, disease incidence, disease severity and pathogen reproduction on peach fruit were evaluated under 10, 15, 20, 25 and 30oC and wetness duration of 6, 12 and 24h. Six of seven parameters of a generalised beta function fitted to conidia germination of M. fructicola and M. laxa were similar. Only the shape parameter was higher for M. fructicola indicating that the range of temperatures and wetness periods favourable for germination is wider for M. laxa than for M. fructicola. The optimum temperature for brown rot development caused by M. -

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. -

With the widespread introduction of trees to many parts of the world, it is becoming of increasing importance to know the susceptibility of trees introduced to new disease situations. Spaulding's comprehensive lists included forest tree diseases caused by fungi, bacteria, and viruses, but not the mistletoes. Therefore this publication on the mistletoes was prepared to supplement his work. Spaulding considered only forest trees, but the coverage here is expanded to include mistletoes parasitic on introduced forest, crop, orchard, and ornamental trees. In some instances, mistletoes are reported on trees cultivated within different parts of a country where the tree is native. Such records are included if it is indicated in the publication that the mistletoe in question is on planted trees. "Mistletoe" as used in this paper refers to any member of the fam- ilies Loranthaceae or Viscaceae. -
