Abstract

The efficacy of dicofol 5% WP (0.0125%), propargite 57% EC (0.018%), ethion 50% EC (0.05%), wettable sulfur 80% WP (0.1%), phosalone 35% EC (0.07%), abamectin 1.9% EC (0.014%), neem seed kernel extract (NSKE; 5.0%), azadirachtin 0.03% EC (5.0%), neem oil (2.0%), monocrotophos 36% EC (0.05%), mahua [Madhuca longifolia] oil (2.0%), endosulfan 35% EC (0.05%) and Vitex negundo leaf extract (5.0%) against spider mite (Tetranychus macfarlanei) on C. moschata was evaluated in Varanasi, Uttar Pradesh, India, from March to June 2002. Pest mortality was evaluated at 1, 3, 7 and 14 days after treatment. Dicofol and propargite resulted in the greatest mean level of mortality (85.66 and 83.55%, respectively), followed by abamectin (81.55%), ethion (78.2%), phosalone (76.66%), monocrotophos (73.44%), endosulfan (71.66%) and wettable sulfur (68.44%). The botanical pesticides, i.e. azadirachtin, neem oil, NSKE, mahua oil and V. negundo leaf extract, were less effective (62.55, 56.44, 52.44, 49.66 and 45.44% mortality, respectively).
