"Pyrethroid, organophosphate, carbamate and cyclodiene resistance levels for\r\nthe cotton bollworm (Helicoverpa armigera) have been monitored routinely\r\nat sites throughout India since 1993 using discriminating dose assays.\r\nResistance by H. armigera and other pests to commonly used insecticides is\r\na severe constraint to cotton production in India. An integrated crop\r\nmanagement strategy was developed aimed at maximising profit while\r\nminimising insecticide use and the impact of insecticide resistance.\r\nAppropriate varieties and agronomy, plus seed treatment where necessary,\r\nallow the first foliar insecticides to be delayed until at least 70 days from\r\nplanting. Insecticides for fruit and leaf feeders are then rotated, taking\r\naccount of seasonal shifts in their efficacy and the pest spectrum faced; with\r\nendosulfan first, followed by particular organophosphates, leaving one to\r\ntwo pyrethroid sprays until the late season when pink bollworm is also\r\npresent. This system (customised for the different regions of India) was\r\ndemonstrated in village participatory trials, reaching 24 villages across four\r\nstates in 1998-9. In all areas the quantity of insecticide a.i. used was reduced\r\nby >29%; yields increased substantially and net profit rose $40 to $226/ha\r\nwhen compared with farmers not in the schemes."^^ .
