Cut flower producers currently have limited options for nematode control. Four field trials were conducted in 2006 and 2007 to evaluate Midas® (iodomethane:chloropicrin 50:50) for control of root-knot nematodes (Meloidogyne arenaria) on Celosia argentea var. cristata in a commercial floriculture production field in southeastern Florida. Midas (224 kg/ha) was compared to methyl bromide:chloropic...

A spectrum of fumigants (primarily ethylene dibromide, 1,2-dibromo-3-chloropropane, ethylene oxide, symdibromotetetrachloroethane, 1,3-dichloropropene, dichlorovos, carbon tetrachloride, methyl bromide) as well as their degradation products in foodstuffs and soil have been examined mainly in regard to the potential mutagenicity of their residues.

The concentration and distribution of a soil fumigant in the subsurface of field plots are two key factors in the determination of the fumigant efficacy. Subsurface concentrations of the biologically active compounds cis- and trans-1,3-dichloropropene (1,3-D) and chloropicrin (CP) were determined in soil at two adjacent injection traces and midpoint between the two traces in plastic-covered fie...

The widespread use of synthetic chemical pesticides beginning in the late 1930s has contributed to development insecticide resistance many important species pest insects and plants. Recent trends pesticide have emphasized more environmentally benign control methods that take into consideration environmental, food safety, human health. Biopesticides (e.g., naturally occurring pesticidal compound...

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...

Rice moth Corcyra cephalonica (Stainton) is a serious pest on storage commodities. The management of C. relies the use chemical pesticides. Insecticide resistance and its effect nontarget demand for compounds that are clean, green. Essential oils (EOs) viz., Trachyspermum ammi (Ajowan), Piper betle (betel), Eucalyptus citriodora (citridora), Cymbopogan nardus (citronella), Pelargonium graveolen...

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...
