Abstract

                                Among the seven insecticides tested for the control of the chilli muranai mite. Polyphagotarsonemus latus (Banks), triazophos 40 EC @0.04% was significantly superior to all other treatments in reducing the mite population both in pot culture, and under field experiments at 7 DAT. The reduction in the population of mites 1anged from 90.60 to 92.20 and 89.04 to 93 68 per cent in pot culture and field exocriments respectively. The next in effectiveness was poosalone 35 EC @ 0.07% with 80-21 to 81.44 and 79.61 to 85.03 per cent reduction of mites in pot culture and field experiments respectively. However, the maximum cost-benefit ratio of 1:9.9 was obtained in methyl-o-demeton application followed by phosalone with 1:69 and monocrotophos with. 1:6.1.
