Abstract

fetched live from OpenAlex

Abstract The toxicity and environmental concerns of methyl bromide (MB) have been a significant impetus for research into environmentally benign fumigant alternatives. Ethyl formate (EF) and chlorine dioxide (ClO 2 ) are FDA‐approved agents with potential as alternatives to MB. However, both are chemically unstable and pose considerable end‐use challenges. In this study, we developed moisture‐activated sachets for EF and ClO 2 to facilitate their end‐use deployment for in‐package fumigation. The sachets were loaded with EF or ClO 2 metastable precursors, citric acid (CA), and a deliquescent salt carrier (e.g., CaCl 2 or NaCl). When placed in an elevated relative humidity environment, these combinations activate the release of EF or ClO 2 gases, separately. The deliquescence lowering phenomenon and its effect on fumigants release rate were investigated when mixing CA with CaCl 2 or NaCl. The mutual deliquescence relative humidity for CA–CaCl 2 and CA–NaCl mixtures were 40% and 63%, respectively. CaCl 2 enhanced the release rate of fumigants from their sachets, whereas NaCl resulted in a slower release rate. EF and ClO 2 sachets were evaluated for fumigation of different life stages of spotted wing drosophila (SWD). Complete control of SWD adults was achieved after exposure to 10.1 mg·h/L EF, while eggs, larval, and pupal stages were more tolerant toward EF vapour and required 110.2 mg·h/L EF to achieve control. ClO 2 at low concentrations was more effective than EF against all SWD life stages, excluding pupae. Complete mortality was achieved after fumigating SWD adults, eggs, and larvae with 0.73, 2.39, and 1.21 mg·h/L ClO 2 , respectively. These results indicated that both EF and ClO 2 sachets could be employed safely for EF and ClO 2 in‐packaging fumigation to control produce pests.

Teacher imitation

Not 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.
