Abstract:
... We previously showed that aqueous extract of prickly pear (Opuntia ficus-indica) cladode has significant antiviral activity against Cucumber mosaic virus (CMV: family Bromoviridae). Antiviral activity of the extract was retained for a period of 9 days on treated faba bean leaves. This activity was considerably decreased at concentrations lower than 30 mg mL−1, and by washing the treated leaves of ...

Abstract:
... Prairie voles (Microtus ochrogaster Wagner) cause extensive damage in agricultural, suburban, and urban environments. Control of these animals has historically relied on the use of anticoagulant rodenticides and zinc phosphide. However, shyness to zinc phosphide baits has reduced its efficacy. The aim of this study was to evaluate the factors involved in zinc phosphide bait shyness through prefere ...

Abstract:
... Ralstonia spp., the causal agents of bacterial wilt, cause severe yield losses of Solanaceous crops, including tomato. The disease is difficult to control due to the pathogen's ability to survive in soil and to cause latent infections. Therefore, characterizing Ralstonia strains is important in developing effective strategies for diagnoses, quarantine and selection of biocontrol agents. In this st ...

Abstract:
... Bait applications are frequently utilised to control the Mediterranean fruit fly, Ceratitis capitata (Wiedemann), because they can be applied rapidly and have a limited impact on natural enemies. However, the preferred toxicant, malathion, sometimes results in unacceptable residues and resistance has been found to it and the most common alternative, spinosad. Cyantraniliprole 100 g/L SE was theref ...

Abstract:
... In Australia, winter annual grasses provide the strongest competition against wheat for resources which detrimentally affects grain yield. With increasing action from government, industry, and grower groups to reduce herbicide spray drift, adoption of drift reduction technologies (DRTs) especially DRT nozzles has increased over recent years. Some herbicides are less effective when sprays are too c ...
