Abstract
The inhibitory effect of mineral oil, synthetic pyrethroid insecticide, organophosphorus insecticide and a pyridine azomethine insecticide on the spread of aphid-borne non-persistently transmitted lily symptomless virus (LSV; carlavirus) and lily mottle virus (LMoV; potyvirus) in Lilium was studied.
The control effect of spray mixtures of mineral oil (Luxan oil H) and pyrethroid insecticide deltamethrin (Decis) serially reported about in the past was confirmed.
The organophosphorus insecticide acephate (Ypsilon) and the pyridine azomethine insecticide pymetrozine (Plenum) applied as single sprays were about half as effective as deltamethrin in the control of virus spread.
The effect of acephate and pymetrozine in mixed sprays with mineral oil proved to be similar in control efficacy as sprays of mineral oil plus pyrethroid.
The impact of this newly found effect and mode of action of the systemic insecticides as additive to mineral-oil sprays is discussed.
