Abstract Many aromatic herbs in the family Apiaceae produce essential oils that are used on an industrial scale for medicinal, cosmetic, and food purposes. Essential from plants show insecticidal activity can be substituted synthetic insecticides to reduce environmental pollution or harmful toxicity humans. Insecticidal of oil seeds coriander, Foeniculum vulgare Miller (Apiales: Apiaceae), maiz...

Balanogastris kolae reduces the quality of stored kolanuts; yet, plants with insecticidal properties could be used to manage this insect pest. The objective study was evaluate efficacy plant oils against B. kolae, a storage pest kolanuts. Citrus aurantifolia fruit peel and Piper guineense seed volatile obtained via hydro-distillation dried, pulverised samples were tested. Their chemical composi...

BACKGROUND The cereal weevil, Sitophilus zeamais is one of the most destructive pests of stored cereals worldwide. Frequent use of fumigants for managing stored-product insects has led to the development of resistance in insects. Essential oils from aromatic plants including the tea oil plant, Melaleuca alternifolia may provide environmentally friendly alternatives to currently used pest contro...

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...

Plastic tarps are often used in soil fumigation to contain chemicals in the soil to increase efficacy and decrease emissions of fumigant vapors. This research has shown that plastic films have a significant capacity to sorb fumigant vapors and that the sorption is largely reversible. We tested three agricultural films (polyethylene and two highbarrier films) with four soil fumigants (methyl bro...
