Eight years of chickpea surveillance exposed disease hotspots that a state average would hide
WHAT THE EVIDENCE SAYS
From 2018–2025, an ICT-based pest-surveillance program tracked chickpea wilt across 5,039 villages in 305 talukas and 28 districts. The study identified persistent hotspot districts and large within-district differences, while overall incidence declined markedly after the 2018–2020 epidemic period. The authors connect the decline with resistant cultivars, Trichoderma-based integrated disease management and mobile advisory dissemination.
WHY IT MATTERS / OUR READ
The strongest contribution is the spatial surveillance architecture: management can be targeted to talukas where disease pressure persists rather than treating a whole state as one risk class. The long record also shows how operational monitoring can turn plant disease into a landscape-management problem.
CAVEATS / UNCERTAINTY
This was not a randomized test of the advisory program. Weather, cultivar adoption, crop rotation, management intensity and surveillance conditions changed through time, so the decline cannot be attributed solely to ICT-enabled integrated disease management.
