title: Use of granulated fertilizers with Actellic EC 50 insecticide in the control of mosquito larvae.
abstract: Granulated fertilizers [ammonium nitrate, synthetic fertilizer] were used as carriers to prepare an insecticide granulate suitable for the control of Aedes cantans and Aedes vexans mosquito larvae under field conditions. The insecticide granulate was obtained by mixing 1 volume unit of Actellic EC 50 with 50 volume units of fertilizer. The optimal dose required to ensure and effective control of Aedes mosquito larvae was 2--5 g of granulate per 1 m3 of water [i.e. 2--5 kg/ha per each 1- cm depth of water] in hatching areas with a relatively clean water or during periods of slow larval growth and development, and 10 g of granulate per 1 m3 of water for hatching places polluted with organic substances or for periods of accelerated larval growth during summer months. The described Actellic EC 50 application practice ensures a complete survival of numerous non-target water organisms, including Tubifex species, Rhynchelmis species, molluscs, flatworms [Turbellaria], Asellus aquaticus, water mites [Hydrachna sp.] water striders (Gerris lacustris] and Dixella species larvae].
