“…Increasing the concentration did not improve the efficiency of preparations. Mineral oils applied independently and in combinations with insecticides reduced the viral inoculum source and spreading in lily, iris, and dahlia cultivations [Asjes 1991, Asjes et al 1996, Asjes and Blom-Barnhoorn 2001. Applying mineral oils at various concentrations and with various frequencies, as well as using the insecticides did not ensure a complete elimination of virus spreading Blom-Barnhoorn 2001, 2002], which is confirmed by the present study.…”

The experiment assess the effectiveness of two mineral oils: Sunspray 850 EC (85% mineral oil) and Sunspray Ultra-Fine (98.8% mineral oil) on tulip 'Leen van der Mark' fields. Tulip plants were sprayed once a week for three weeks. Mineral oils were applied at concentrations of 1.0, 1.5, and 2.0%. The oil preparations did not negatively affect the length of flower shoot and tepals of tulips grown in field. No phytotoxic symptoms were observed on leaves, however their color was altered. In all combinations protected using oils, the number of plants with virus symptoms on petals was lower than for control. No decrease in the commercial and the first choice bulb yields due to the mineral oils application were recorded. Mineral oils applied at concentration up to 2.0% had no negative contribution on the quality of produced tulip flowers. Despite of the selection made in the field, from 60 to 73% plants showed virus symptoms in control combination during plant forcing. Efficiency of oils in reducing the spread of viruses depended on the year of study and oil type. The best effects were achieved using Sunspray 850 EC at 1.5% concentration (26% virus-infected plants). The oil preparations, despite of high efficiency in reducing the virus spread, did not guarantee a full protection in the field in any year of study.

“…A treatment with olive oil, which also has a repellent effect on B. tabaci adults, was reported to suppress the TYLCV infection simply by reducing the number of settled adults (Schuster et al, 2009). Mineral oil is also effective in reducing the spread of non-persistent viruses that are transmitted by aphids (Asjes, 1991;Bradley et al, 1962;Loebenstein et al, 1964; , 2004;Wang and Pirone, 1996). Based on the high reduction of honeydew excreta in the acetylated glyceride treatment, a major mechanism for suppression might be interference with adult feeding behavior.…”

“…This large difference between the tests was presumably caused by the presence or absence of a refuge area for settling after being repelled. In a similar study, 7-epizingiberene purified from Solanum habrochaites exhibited a strong repellent effect on B. tabaci adults in a choice test, whereas all of the individuals were observed to settle on a host plant within 2 h after release in a no-choice test, even though the substance had adulticidal activity (Bleeker et al, 2011). The mature glandular trichome exudates of tomato plants are crucial mechanisms for resisting adult whitefly settlement via repulsion and entrapment (Muigai et al, 2002).…”

“…Moreover, whether the addition of oil, which is a type of adjuvant, allows one to decrease the dose of the insecticide without losing its effectiveness? Many studies have previously described the possibility of applying mineral oils together with insecticides in the protection of various plants against viruses (Lowery et al 1990, Marco 1993, Weeb and Stephen 1993, Asjes 1991. In the case of potatoes, much of the research has been based on using out-of-date and often no longer available pyrethroids (Bell 1989, Gibson and Rice 1986, Rolot et al 2008 or on comparing the effectiveness of protection against viruses between oils and insecticides or mixtures of insecticides only (Martín-López et al 2006, van Toor et al 2009, Olubayo et al 2010.…”

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...
