“…TOF-MS analyses demonstrated that the increased aphid mortality would not be due to the increased penetration or accumulation of imidacloprid, since the concentration of imidacloprid found in aphids treated with the combined mixture was similar to the concentration found in aphids treated with low-dosed imidacloprid alone. The synergistic effects of the plant oil formulations on aphid mortality may be an explanation for the increased mortality, as demonstrated earlier (Puri et al, 1994;Horowitz et al, 1997;Rao and Dhingra, 1997;Liu and Stansely, 2000). The plant oil formulations are expected to play the roles of wetting, spreading and sticking agents on aphids.…”

Aphids are one of the major pests in agricultural crops. A number of synthetic pesticides have been used for control of aphids in agriculture, but increasing public concerns over their adverse effects on the environment have required more environmentally-friendly methods for pest management. In this study, we examined plant oil formulations for the control of green peach aphid (Myzus persicae). Oil formulations were prepared by hydrolyzing the plant oils in ethanolic KOH solution and diluted at the rate of 1:500 for aphid control. The oil formulations showed aphid mortalities ranging from 24.44 to 43.33% in vitro. Significantly increased aphid mortalities were observed by the treatment of oil formulations combined with low-dosed imidacloprid. No significant difference in the aphid mortality was observed between the oil formulations. Mass spectrometry analyses of aphids treated with the low dosedimidacloprid plus the plant oil formulations detected similar concentrations of imidacloprid between the treatments. In field trial bioassays against aphids, significantly decreased aphid population were observed in the pepper plants treated with soybean oil formulation combined with the low-dosed imidacloprid, while aphid population dramatically increased in the pepper plants treated with the low-dosed imidacloprid alone. These results suggested that the plant oil formulations can be used as an environmentally-friendly method for enhancing the insecticidal effectiveness, which may play a role in reducing the use of synthetic pesticide in agriculture.

“…The effectiveness of the remaining combinations of the insecticide with mineral oil, or insecticideonly treatments, was too small, compared to oil only, to be practically useful. Many authors point to better penetration and higher effectiveness of the insecticide when applied in combination with the mineral oil, as compared to when used on its own (Moustafa and El-Attal 1985;Horowitz et al 1997), yet this dependency is not always replicated for all insecticides (Treacy et al 1991;Pree et al 1996). Martin-López et al (2006) claim that in spite of the absence of any reduction of aphids numbers on potatoes, mineral oil was much more effective in reducing the level of PVY tuber infection than cypermethrin, following the usage of which, 4 times fewer aphids were recorded.…”

The impact of a dozen mixtures of the most commonly applied aphicides: Mospilan 20 SP (acetamiprid), Pirimor 500 (pirimicarb) and Karate Zeon 050 CS (lambdacyhalothrin), combined with the mineral oil Sunspray 850 EC, was researched in field conditions to assess their effectiveness in limiting potato tuber PVY, PVM and PLRV infection. In spite of the greatest reduction in the number of aphids occurring following application of Mospilan 20 SP, this treatment was not as effective in limiting PVY infection as, for example, applying Sunspray 850 EC mineral oil. Mineral oil, when used on its own or in a mixture with Pirimor 500 WG, was found to be the most effective measure for limiting PVY infection (the incidence of tubers infested with PVY was reduced by 64 % relative to control, i.e. no protection). A slightly weaker effect was observed in the case of a combination of the mineral oil with full doses of Karate Zeon 050 CS with a half of a dose of Mospilan 20 SP insecticide, however only for protection against PVY. A similar trend was observed for PVM even though a significant difference was only observed for Sunspray 850EC+Pirimor 500WG. In conclusion, the application of insecticide mixtures with mineral oil in protecting against PVY infection is not always as effective as the application of the oil itself only. Addition of the insecticide may sometimes improve the efficacy of protection, however, due to the extra costs involved, not always does it have to be economical.Resumen Bajo condiciones de campo, se investigó el impacto de una docena de mezclas de los siguientes aficidas más comúnmente aplicados: Mospilan 20 SP (acetamiprid), Pirimor 500 (pirimicarb) y Karate Zeon 050 CS (lambdacyhalothrin), combinados con el aceite mineral Sunspray 850 EC, para evaluar su efectividad en limitar la infección de tubérculo por PVY, PVM y PLRV. A pesar de la mayor reducción en el número de áfidos que se presentaron después de la aplicación de Mospilan 20 SP, este tratamiento no fue tan efectivo en limitar la infección de PVY como, por ejemplo, con la aplicación del aceite mineral Sunspray 850 EC. El aceite mineral, al usarlo solo o en mezcla con Pirimor 500 WG, se encontró que era la medida más efectiva para limitar la infección de PVY (la incidencia de tubérculos infectados con PVY se redujo en un 64 % con respecto al testigo sin protección). Se observó un efecto ligeramente más débil en el caso de la combinación del aceite mineral con dosis completa de Karate Zeon 050 CS con la mitad de la dosis del insecticida Mospilan 20 SP, aunque fuera solamente para protección contra PVY. Se observó una tendencia similar para PVM, aun cuando se observó diferencia significativa solamente para Sunspray 850EC+pirimor 500 WG. En conclusión, la aplicación de mezclas de insecticidas con aceite mineral en la protección contra la infección de PVY no es siempre tan efectiva como la aplicación únicamente del aceite solo. La adición del insecticida puede mejorar algunas veces la eficacia de la protección, no obstante, debido al costo extr...

“…The effects of abamectin applied alone or together with the mineral (paraffinic) oil Ultra Fine on sweetpotato whitefly, B. tabaci, were determined on cotton plants under laboratory (leaf dip bioassays) and field conditions (Horowitz et al 1997). This study showed that a mixture of abamectin with mineral oil exhibits higher toxicity than abamectin applied singly.…”
