In this study we present the results of efficacy of plant extracts from Sophora (Sophora flavescens) and Neem (Azadirachta indica) in greenhouse pest control. Bioassays were performed on aphids and spider mites in order to compare the pesticidal activity of new preparative form and extracts from Sophora flavescens and NEEM-01 with that of the commercial biorational products Pelecol and MatrinBio. The extact NEEM- 01 at a dose of 10 l/ ha has potential as aphicide and acaricide, although in terms of efficacy in controlling aphids and mites it is different. NEEM-01 was quite effective against the aphid population compared to spider mites, which are more mobile, ceasing to feed on the treated leaf. A higher mortality of pests with higher biological efficacy of NEEM- 01 was achieved after two treatments with an interval of 10 days between them.
