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