Bu çalışmada, Fumigant olarak uygulanan farklı dozlardaki (1, 3, 5 µl/l-1 hava dozu) nane esansiyel yağının Ephestia kuehniella (Zeller)’in iki gelişim evresinin (son dönem larva ve ergin dişi) biyolojik parametreleri üzerindeki zamana bağlı etkisi incelenmiştir. Nane uçucu yağına maruz kalan son evre larvaların koza örme süresi, puplaşma pupal periyot, öncesi süresi ağırlığı ile birlikte bu di...

Minimizing fumigant emissions is required for meeting air-quality standards. Application of organic materials to surface soil has been effective in reducing fumigant emissions during laboratory tests, but the potential to reduce emissions in the field has not been adequately evaluated. The objective of this study was to determine the effect of incorporated composted manure with or without water...

712 Soil physical conditions can aff ect diff usion, environmental fate, and effi cacy of fumigants in soil disinfestation treatments. Water seals (applying water using sprinklers to soil following fumigation) can eff ectively reduce fumigant emissions from sandy loam soils. Soil column studies compared the eff ectiveness of water seals in reducing cis-1,3-dichloropropene (1,3-D) emissions from...

Low permeability tarps can effectively minimize fumigant emissions while improving fumigation efficacy by retaining fumigants under the tarp. However, when planting holes are cut through the tarps, high-concentration fumigants may be released and result in environmental and worker safety hazards. In a 11-day column study, we explored the effect of drip irrigation application of ammonium thiosul...
