Abstract
Watermelon (Citrullus lanatus) is a key export crop for Brazil with substantial economic value. In November 2019, watermelon plants displaying symptoms of root rot and vine decline were observed in commercial fields in Rio Grande do Norte. Root fragments from symptomatic plants were disinfected, cultured on potato dextrose agar and identified as Macrophomina spp. DNA analysis confirmed the species as M. euphorbiicola. Pathogenicity tests showed severe symptoms in inoculated plants. This is the first worldwide report of M. euphorbiicola causing root rot in watermelon, highlighting the disease's significance.
期刊介绍:
Journal of Phytopathology publishes original and review articles on all scientific aspects of applied phytopathology in agricultural and horticultural crops. Preference is given to contributions improving our understanding of the biotic and abiotic determinants of plant diseases, including epidemics and damage potential, as a basis for innovative disease management, modelling and forecasting. This includes practical aspects and the development of methods for disease diagnosis as well as infection bioassays.
Studies at the population, organism, physiological, biochemical and molecular genetic level are welcome. The journal scope comprises the pathology and epidemiology of plant diseases caused by microbial pathogens, viruses and nematodes.
Accepted papers should advance our conceptual knowledge of plant diseases, rather than presenting descriptive or screening data unrelated to phytopathological mechanisms or functions. Results from unrepeated experimental conditions or data with no or inappropriate statistical processing will not be considered. Authors are encouraged to look at past issues to ensure adherence to the standards of the journal.
