The recirculatory fumigation by ethylene oxide was considered to be an effective method that treats imported wheat with TCK.

In order to keep the ethyl formate(EtF) toxicity results from being enhanced by carbon dioxide(CO2) and obtain more accurate toxicity data of EtF,fumigations were conducted using flow-through fumigation system(FTFS) to investigate the response of mixed stage cultures of the most tolerant insect species,Sitophilus oryzae(L.

Study on ZXX-65 vacuum circulatory fumigation equipment to fumigate wood borer;

Study on ZXX-65 vacuum circulatory fumigation equipment to fumigate storage pests.;

Technologic exploration of natural deliquescence and recirculation fumigation of dichlorvos mixed with aluminium phosphide;

The results showed that recirculation fumigation using AlP tablets dynamic deliquescence in ventilation ducts,which can be manipulated outside the warehouse,was safe,effective,economical and easy operation,and was a method of producing gas matched with phosphine circutation fumigation.

According to the characteristic of high temperature and high humidity in south Chine,choosing the best opportunity to control insects and the suitable control dose,and improving the heat insulation,the large warehouse may realize the recirculation fumigation once a year to kill the stored grain insect thoroughly,reduce the dose,delay aging speed of the grain quality.

Research on administration aluminum phosphade on the grain surface with unilateral circulation fumigation in large warehouse;

It is a kind of gas producing method with phosphine circulation fumigation, which should be recommended.

Natural AlP deliquescence and PH 3 mixed with CO 2 circulation fumigations were chosen directly against the poor airtight in reinforced concrete silos.
