AIMS To evaluate the field inactivation of Bacillus anthracis Sterne spores with methyl bromide (MB) using commercial fumigation techniques. METHODS AND RESULTS Eighty-seven wood and 87 glass coupons each containing ca. 1 × 10(6) B. anthracis Sterne spores, were placed in 22 locations inside a 1444 m(3) conference building. Four additional 12-coupon sets (six wood, six glass) were removed fro...

English with German summary. Cuttings of a poplar clone (Populus x euramericana 'Dorskamp') were exposed to filtered air and to filtered air with 80 to 135 nl I" NO2 added in climate chambers during 12 weeks. Thr...

In intensive strawberry production, monoculture is a common practice worldwide; however, prolonged replanting can cause plant disorders and jeopardize profitable cultivation of this highly valuable crop. To mitigate problems, the industry still dependent on chemical fumigation. Given increasing regulatory restrictions concerns about human environmental risks from fumigants use, there growing in...

A comparative study of formaldehyde (HCHO) fumigation was carried out by controlled vaporization, using an electric vapor generator, and by the Formalin-permanganate method. Determination of vapor levels as well as bactericidal action showed the generator to be more effective. Maximum achievable fumigant levels were temperature dependent and related to the equilibrium vapor concentration of HC...

Currently hydrogen cyanide (HCN) is industrially produced in the Czech Republic (Lucebni zavody Draslovka Kolin) and is extensively used for Czech mill fumigation. Therefore we evaluated the potential of HCN fumigant for treatment of wooden transport packages (pallets). We tested the penetration of HCN trough wooden pallet materials using gas chromatography. The preliminary results on biologica...
