  The study was conducted to evaluate the insecticidal action of two new chemical insecticides and three locally available botanicals. These materials were evaluated for their efficacy against cabbage aphids, Brevicoryne brassicae (L.), under laboratory and field conditions. The laboratory result revealed that Lambda Cyhalothrin (Triger 5 E.CTM) and Emamectin benzoate (Cutter 112 E.CTM) were non-significant difference from the standard check within 1 day after application. The field results showed between the new insecticides, Triger 5 E.CTM and Cutter 112 E.CTM were non-significant difference from that of the standard check (Diazinon 60% E.CTM) at both locations (Guder and Mutulu) within three days after application. Extracts of neem (Azadirachta indica) seed, Hop bush (Dodonae angustifolia) fresh leaf and Lemon grass (Cymbopogon citrates) gave positive performance under laboratory whi.. View More»
