A field trial was conducted to assess the efficacy of some plant products viz., neem seed kernel extract (NSKE), petroleum ether extract of rhizome of Acorus calamus and methanol extract of seeds of Annona squamosa, in controlling fruit fly, Bactrocera cucurbitae, Coq. on ‘Barapata’ variety of cucumber. Results indicated reduction in fruit damage in the range of 53.57% – 68.63%, 43.60% – 64.82% and 43.46% – 63.72% in treatments with NSKE, methanol extract of A. squamosa seeds and petroleum ether extract of A. calamus rhizome, respectively. Endosulfan was able to bring about 62.93% – 77.14% reduction in fruit damage made by B. cucurbitae. No phytotoxicity was observed.
