Fumigation enclosures for raisins are proven to keep a lethal level of gas, protecting stored fruit from pests.
This edition summarizes tests of eight enclosure types used to fumigate raw-stock raisins, showing how different designs retain fumigant and achieve high mortality among common raisin insects.
In these studies, methyl bromide was applied at regulated dosages and gas movement was carefully monitored. Results demonstrate that all tested enclosures could retain enough fumigant for effective pest control, with some variation in gas retention based on material and weathering. The research also compares empty and loaded chambers, and notes how weathering can influence gas retention over time. Insect mortality was complete in the evaluated tests, and sifting of raisins confirmed the absence of living pests after fumigation.
- Eight enclosure types were evaluated for gas retention and pest kill
- Weathering effects on gas retention were tracked over time
- Insect mortality was confirmed for common raisin pests
- Procedures detail dosage, gas sampling, and leak checks
Ideal for readers of practical research on stored-product protection and fumigation methods.
