Some Keys and Discussion about Recommended Regulation of Phosphine Fumigation for Chinese Grain Storage
A recommended state standard for phosphine recirculation fumagation in grain storage industry in china was made. The basic condition is required on gastightness, equipment,instrument and relative materials. The scheme should be made according to the condition of grain quality, insects and their resistance, stacking method, climate and temperature of grain, safety issues and so on. The monitoring on phosphine, concentration maintaining by fumigant reinforcing, and insect detection by test insect cages as keys are recommended during the fumigation. The dosage of tablets of aluminium phosphide is determined by the planned phosphine concentration according to the insect species, resistance, density of insect per kilogram of grain, temperature of grain, schemed fumigating time, gastightness et al. The process about tablet applying methods or phosphine generator operating, phosphine recirculation time,concentration monitoring time and some issues on fumigant distribution is suggested. On the other hand, the recommonded data are effective for insect pest control in many cases. There are some technical issues which should be discussed due to a huge of changes happened in practice in last several years.
