Morphological and Molecular Characterization of Fungal Plant Pathogens Potentially Involved in Root Necrosis Disease of Cassava in the West of the Democratic Republic of Congo
Bibliographic record
Abstract
Cassava root necrosis disease, a serious disease threatening cassava crops, was first reported in Kinshasa and Kongo Central in the Democratic Republic of Congo in 2003. Initial attempts to identify viral pathogens failed, revealing instead a complex of fungal and bacterial pathogens. The etiology of Cassava Root Necrosis Disease remains unclear, as no single pathogen has been identified as the primary cause. The objective of this study was to characterize the fungal microorganisms potentially involved in cassava root necrosis disease. Morphological and molecular analyses identified 18 isolates as belonging to the species Fusarium solani and 2 to the species Trichoderma sp., while two isolates remained uncharacterized. These results contribute to the understanding of the complex etiology of cassava root rot.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
