Fall armyworm/pink bollworm

Technology & Product Transition · Product & process shift

What it is

The two pest outbreaks that reshaped Indian crop protection. Pink bollworm developed resistance to Bt cotton from around 2015, returning a pest the technology was meant to control

Fall armyworm, an invasive species detected in India in 2018, spread rapidly through maize and other crops, attacking a host range wide enough to cross cropping systems

Impact on industries

  • Demand driver for the agrochemical sector - resistance and invasion both create urgent, price-insensitive spray demand that recurs season after season
  • Rewards companies with newer chemistries and biologicals, since resistance erodes the efficacy of older molecules farmers had defaulted to
  • Demonstrates the limits of a single-trait technology strategy: pink bollworm resistance undermined the value of Bt cotton without an approved replacement trait available
  • Outbreaks are lumpy and unforecastable, so the revenue is not a plannable base, and severe infestation destroys the income funding next season's inputs
