In what is a first for the world, leaf spot disease of sweet potato, caused by Boeremia exigua, is reported in Brazil. Identity of the fungus was confirmed by a combination of molecular and morphological data. Koch?s postulates were fulfilled with a selected isolate of the fungus obtained from Santa Maria do Jetibá, state of Espírito Santo, Brazil. Ipomoea batatas (Convolvulaceae) - sweet potato - is the sixth most important food crop worldwide (CIP 2020). Several diseases are limiting factors for this crop, including field and storage diseases (Clark et al. 2013). In Brazil, sweet potato has lost some of its former importance because of changes in the consumer?s habits but still remains one of the top vegetables in Brazilian agriculture (Silva et al. 2008). These authors listed several fungal diseases that occur on sweet potato in Brazil, but considered that damage to the crop by fungal diseases is normally small. In June 2015, sweet potato plants bearing severe leaf spot damage were observed in a plantation in the municipality of Santa Maria de Jetibá (state of Espirito Santo, Brazil). Lesions were initially circular but became irregular, slightly sunken and zonate, dark brown, surrounded by a chlorotic halo, coalescing and leading to a blight of part or entire leaves (Fig. 1a). Older lesions often became torn in their central parts. Numerous, black dots were repeatedly seen immersed in the necrosed tissues when viewed using magnifying lens.

The Mediterranean fruit fly (Medfly), Ceratitis capitata (Wied.), is a pest of quarantine importance that usually only infests papaya fruits in advanced stages of maturity. However, some diseases, such as sticky disease of papaya plants, caused by the Papaya meleira virus (PMeV), break the natural resistance of fruits to fruit flies, enabling them to be infested while still unripe. Therefore, this study of the relationship of papaya sticky disease with C. capitata under field conditions was conducted to determine the period of security to guarantee the harvest of papaya fruits free of fruit flies in areas where sticky disease is endemic. Infestation of papaya fruits by C. capitata was evaluated from uninfected plants and from sticky disease infected plants, in seven stages of the disease and three stages of ripening of fruits. A direct relationship was observed between time of sticky disease symptoms and infestation of fruits by the Medfly, and it was determined that a period of four weeks after the first appearance of the symptoms of sticky disease in papaya plants was the period of security in which infestation of fruits by fruit flies did not occur. Infection of papaya plants with sticky disease was associated with a reduced level of benzyl-isothiocyanate (BITC), from 43.1 ?g ml?1 to 1.7 ?g ml?1, a natural chemical compound in the latex of papaya fruit, and considered to be associated with resistance to fruit flies. |
