Resumen:
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.
Durante 2018 y 2019, en el sur de Uruguay se relevaron las enfermedades asociadas al cultivo de cannabis (Cannabis sativa). Se aisló Neofusicoccum sp. desde plantas con síntomas de cancro en tallos en tres de los cinco cultivos relevados, siendo el tercero en prevalencia. Con el objetivo de conocer el agente causal del cancro de tallo y rama en cannabis, tres aislados de Neofusicoccum sp. se caracterizaron mediante análisis morfológico y molecular, además de prueba de patogenicidad en plantas de cannabis. Se identificó N. parvum como agente causal del cancro de tallos en plantas de cannabis en Uruguay.
No 2018 e 2019 no Uruguai, foram pesquisadas pragas e fungos associados a doenças em cultivos de cannabis (Cannabis sativa) no sul do país. Neofusicoccum sp. foi isolado de plantas com sintomas de cancro em caules em 60% das lavouras, ocupando o terceiro lugar entre os fungos mais freqüente. Com o objetivo de conhecer o agente causal do cancro do caule e galho em cannabis, três isolados de Neofusicoccum sp. foram caracterizados por análise molecular morfológico, também a patogenicidade em plantas de cannabis. Neofusicoccum parvum foi identificado como o agente causal do câncer de caule em plantas de cannabis no Uruguai.
