There is no doubt that anthropogenic climate change, increasingly evident nowadays, has a major impact on the emergence of crop diseases, particularly on rusts. The 21st century has witnessed pandemics of rust in several hosts, such as soybeans, grapevine, Myrtaceae, among others. Invasive rust pathogens have been responsible for high losses in the crops in which they occur, including in …

This research project was motivated by the exaggerated number of fungicides spraying by the growers of São Paulo State for the control of grape diseases. Recent estimates indicate that the control of fungal diseases has been performed with 103 and 59 fungicide spraying each season in vineyards of european (Vitis vinifera) and american grapes (Vitis labrusca), respectively, in the State of…
Control of postbloom fruit drop (PFD) of citrus in the southwestern region of São Paulo state, where PFD is more prevalent, has been achieved using preventive, calendar-based fungicide applications. While PFD occurs frequently in the region, infection levels vary significantly, causing high losses when winters are rainy such as in 2009, and not affecting production during years with drie…

The occurrence of rust has increased considerably in recent years in various agricultural regions around the world, resulting in various economic and environmental damages. Only recently, research on the effect of the combination of biotic and abiotic stresses, in simultaneous occurrence, on the physiology of cultivated plants are being carried out. Although the individual effects of wate…
The impacts of global climate change represent one of the greatest challenges facing humanity nowadays. Future scenarios projected by the Intergovernmental Panel on Climate Change (IPCC) threaten biodiversity and food production globally. Climate change impact on crop production has been the focus of many recent studies. The State of São Paulo is the largest Brazilian producer of guava, r…

Phyllosticta citricarpa, the causal agent of citrus black spot (CBS), produces two types of spores: ascospores and pycnidiospores. Pycnidiospores are responsible for the secondary cycles of the disease, while ascospores are responsible for both primary and secondary cycles. There are few studies on the environmental conditions favorable to ascospores germination due to the difficulty to p…
Myrtle rust, caused by Austropuccinia psidii, is the most severe fungal disease in guava plants, especially cv. Paluma. Rust in perennial plants usually cause polyetic damage, it is possible to estimate the polyetic damage in a greenhouse, by means of multiple inoculations in potted plants. The objective of this work will be to estimate the impact of successive inoculations of A. psidii o…
Myrtle rust (Austropuccinia psidii) is an important disease on guava (Psidium guajava) and other species of the Myrtaceae family. There are several studies carried out with this pathogen in eucalyptus, but very little information is available about this disease in other hosts of the Myrtaceae family. Intraspecific diversity has already been observed in A. psidii, but most studies provide …

The BEPE project complements the activities that are being carried out in the experiments involving successive inoculations of the pathogen Austropuccinia psidii in 'Paluma' guava seedlings in Brazil. The biochemical and metabolic analyzes to be carried out in Lorraine University will contribute to the understanding of the dynamics of carbon in the diseased guava plants. The following var…
The 2-month BEPE internship, to be held at RWTH Aachen University, under the supervision of Prof. Dr. Ulrich Schaffrath, aims to complement the results obtained by the scholarship holder in Brazil. The student determined that isolates of Austropuccinia psidii from guava (Psidium guajava), when inoculated onto rose apple plants (Syzygium jambos), an ostensibly susceptible species to A. psi…
Downy mildew caused by Plasmopara viticola is the most destructive disease of Vitis vinifera worldwide. Grapevine breeding programs have introgressed P. viticola-resistant traits into cultivated V. vinifera genotypes and launched interspecific hybrids with resistance against downy mildew. Defense mechanisms of grapevine to P. viticola comprise pre-existing chemical defenses and induce str…
Control of grapevine diseases, including downy mildew (Plasmopara viticola) and Asian grapevine leaf rust (Phakopsora meliosmae-myrianthae) in the main grape-growing regions of Brazil has been achieved using foliar fungicide applications programmed at fixed intervals. A survey conducted with table grape growers from Northwest São Paulo State showed that the number of fungicide application…
