To prevent the great damage, the compatibility of the microbiological insecticide Foray 48B and microbiological fungicide AQ10 was analysed in laboratory conditions, as the components of a mixture with insecticide and fungicide properties, which can be applied in the synchronic suppression of defoliators from the Lepidoptera order and powdery mildews. The application of the above mixture could prevent the succession of some harmful biotic factors and the further chain-linking of adverse effects. Izvod: Posle intenzivnog brsta na hrastovima i šumskim višegodišnjim vrstama voćkarica i aromatičnog bilja, koji mogu prouzrokovati rani defolijatori i gubar kada se jave u prenamnoženju, novo mlado lišće je osetljivo na napad pepelnica (izazivači patogene gljive iz reda Erysiphales). Da bi se sprečile veće štete, u laboratorijskim uslovima, istražena je kompatibilnost mikrobiološkog insekticida Foray 48B sa mikrobiološkim fungicidom AQ10, kao komponenti mešavine sa insekticidnim i fungicidnim svojstvima, koja bi se mogla primeniti za istovremeno suzbijanje defolijatora iz reda Lepidoptera i pepelnica. Primena navedene mešavine sprečila bi sukcesiju nekih štetnih biotičkih faktora i dalje ulančavanje šteta.
