VOSTŘEL, Josef, Markéta TREFILOVÁ and Ivo KLAPAL. The control of damson-hop aphid (Phorodon humuli Schrank) and two-spotted spider mite (Tetranychus urticae Koch) by Rock Effect New (Pongamia pinnata). In: F. WEIHRAUCH, ed. Proceedings of the Scientific-Technical Commission 25–29 June 2023, Ljubljana, Slovenia. Wolnzach: Scientific-Technical Commission of the International Hop Growers' Convention, 2023, pp. 25–28. ISSN 2512-3785. Damson hop aphid (Phorodon humuli Schrank) and two-spotted spider mite (Tetranychus urticae Koch) are the most dangerous pests of hop in Czech Republic. In practice they are controlled by synthetic insecticides and miticides. Nevertheless, many of them are endangered by EU restrictions. So as to be able to cope up with these pests after 'Green Deal' comes in force it is critical to look after adequate alternatives. Botanical pesticide Rock Effect New (Pongamia pinnata) showed good efficacy on damson hop aphid and two-spotted spider mite in field trials carried out in 2022. Nevertheless, repeated application is necessary for efficient control. No phytotoxicity was observed if applied in 1.0 and 1.5 % concentrations. Synergism with spirotetramat does not show increase in biological efficiency. Surviving aphids and spider mites can be controlled by aphidopahagous and acarophagous predators thanks to selective effect of Rock Effect New.
