Antifungal Studies of Selected Essential Oils and a Commercial Formulation against Botrytis Cinerea
Bibliographic record
Abstract
<p>Growing concerns about food safety and environmental protection have created a need for new and safe plant disease control strategies. The aim of this study was to find an alternative to synthetic fungicides currently used in the control of the devastating fungal pathogen <em>Botrytis cinerea</em> Pers., the causal agent of grey mould disease of strawberry (<em>Fragariaananassa </em>Duch). The antifungal activity of the essential oils of <em>Origanumvulgare</em> L., <em>Monardadidyma</em> L. and of a commercial formulation of thyme oil (Gloves Off®) was investigated against <em>B. cinerea</em> and compared with controls. Contact phase effects of different concentrations of the essential oils and commercial formulation were found to inhibit the growth of <em>B. cinerea</em> in a dose dependent manner. Complete growth inhibition of the pathogen was recorded at 200 µg/ml of ‘Gloves Off®’. The mycelial growth of the pathogen was significantly reduced at the highest concentration of the essential oils of <em>O. vulgare</em><em> </em>and<em> M.</em><em> didyma</em> tested, which was 51.2 µg/ml. Spore germination and germ tube elongation were also inhibited by the essential oils and Gloves Off®. Light microscopic observations revealed that the essential oils caused morphological degenerations, such as cytoplasmic coagulation, hyphal shrivelling and protoplast leakage of the fungal hyphae. The essential oils of <em>O.</em><em> vulgare</em> L. and <em>M.</em><em> didyma</em> L. are promising, antifungal agents against <em>B. cinerea</em>similar to the commercial formulation ‘Gloves Off®’.</p>

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
