The Center for Agricultural Research in Suriname (CELOS) has conclusively identified the causative agent behind the cassava disease that has been affecting agricultural regions since late 2025. Through comprehensive laboratory analysis, researchers have confirmed that the pathogen responsible is the fungus Ceratobasidium theobromae, internationally associated with Cassava Witches’ Broom Disease (CWBD).
This plant disease severely impacts cassava crops, leading to significant growth retardation and substantial yield losses. Symptoms observed since November last year include broom-like branching patterns, deformed shoots, and noticeable plant stunting across multiple cassava fields.
The scientific confirmation came through molecular laboratory testing directed by biologist Krishna Gopie, utilizing field samples collected by CELOS scientist Rudi Nelom in collaboration with the Ministries of Agriculture, Animal Husbandry and Fisheries (LVV) and Regional Development (RO). DNA analysis successfully detected genetic material from the fungal pathogen, with tests conducted using international reference materials and control samples to ensure result reliability.
This breakthrough is considered critical for Suriname’s agricultural sector, where cassava serves as both a staple food source and primary income generator for farmers. Accurate diagnosis enables targeted monitoring and control measures while helping prevent further spread through contaminated planting materials.
CELOS emphasizes that this discovery underscores the vital importance of local scientific research in protecting national agricultural interests. The institute will collaborate with LVV and RO to conduct follow-up studies on disease distribution and potential impacts. Additionally, educational programs will be implemented to inform farmers about symptom recognition and responsible use of planting materials.
CELOS Director Jairam has urged cassava growers to remain vigilant for signs including excessive branching, abnormal shoot development, and growth retardation. Suspicious plants can be reported to the Plant Pathology Department for further investigation. The research center stresses that close cooperation between scientists and agricultural producers is essential to minimize further damage to cassava cultivation and protect food security.
