Abstract

SASIA, E. et al. First report of Neofusicoccum parvum causing stem canker on cannabis in Uruguay. Agrocienc. Urug. [online]. 2023, vol.27, e1172.  Epub Dec 01, 2023. ISSN 2730-5066.  https://doi.org/10.31285/agro.27.1172.

In 2018 and 2019, in Uruguay, pests and fungi associated with diseases were surveyed in cannabis (Cannabis sativa) crops in the south of the country. Neofusicoccum sp. was isolated from plants with canker symptoms on stems in 60% of the crops, occupying the third place of the most frequent fungi. In order to determine the causal agent of stem and branch canker in cannabis, three isolates of Neofusicoccum sp. were characterized by morphological and molecular analysis, as well as pathogenicity in cannabis plants. Neofusicoccum parvum was identified as the causal agent of stem canker in cannabis plants in Uruguay.

Keywords : Botryosphaeriaceae; Cannabis sativa; hemp; identification; pathogenicity.
