Jackfruit (Artocarpus heterophyllus) is an important fruit crop in Brazil, and it is commonly found in commercial plantations or spontaneous plants across the whole country. Anthracnose caused by Colletotrichum spp. is among the most important diseases of jackfruit. However, it is unclear which Colletotrichum species is responsible for this disease in Brazil. In 2018, in Goiás, Paraná and São Paulo states, and Distrito Federal (Brazil), jackfruit leaves presented necrotic foliar lesions with dark edges, light center, and chlorotic halo. Incidence of diseased leaves per plant was low (1 to 5%) and lesions were concentrated on the older leaves. Eight Colletotrichum isolates obtained from symptomatic leaves were assigned to the species C. siamense based on phenotypical and molecular features. Their pathogenicity was confrmed by inoculation on jackfruit seedlings and reisolation of the pathogen from induced lesions. Also, the isolates were pathogenic to leaves of soursop, cashew, and mango, which indicates non-host specifcity to the original host. |

Purpose: Riparian zones are identifed as mitigation areas of agricultural pollutants to river ecosystems. However, the miti? gation mechanisms of these pollutants remain unclear mainly on the efects of diferent types of riparian vegetation and its organic matter content in the pollutants removal process. This study aims to assess the content of organic matter in soils composed of woody vegetation and grass and its efects on four pesticides adsorption. Adsorption studies were conducted in soil collected in riparian vegetation areas composed of grass and trees under the infuence of an agricultural area. Methods: The analyses were performed in 21 shakers containing 100 g soil and a L of water previously contaminated with pesticide that were stirred for 30, 60, 120, 240, 360, 720, and 1440 min. A study was made of maximum adsorption capacity using the time 360 min and the concentrations of 5, 20, 40, and 50 ?g L?1. Results: The soils of woody vegetation areas had a higher concentration of organic matter as compared with grass areas, and time 360 min achieved the highest adsorption capacity with minimum values of 84% adsorption for the area of land made up of trees and 67% for grass areas. The soils of woody vegetation areas had a higher concentration of organic matter as compared with grass areas, time 360 min. Conclusion: The best adsorption capacity was obtained with minimal adsorption amounts of 84% to the area of soil composed of 67% for trees and grass areas. |
