AI-counted pink-bollworm traps and threshold-based spray advisories

Farmers can spray against a shared trap-count threshold instead of a calendar or subjective visual assessment.

An editorial scene for Wadhwani AI CottonAce partner programs contrasts inspect fields and decide pesticide timing from experience, visible damage, or calendar practice. with checks pheromone traps weekly and uploads smartphone images. in the ai-counted pink-bollworm traps and threshold-based spray advisories workflow.

Executive brief

The operating-model shift, in one view.

This case is valuable because the larger later test was null: AI advice creates value only when the targeted risk is present and the human sensing routine is sustainable.

AI value · Farmer income in initial field evaluations

Verified

Up to 22% higher income in the first-year evaluations; no significant benefit in the 2021-2022 multi-state experiment

The mixed evidence is essential: early evaluations were not all randomized, and unusually high rainfall with low pest pressure eliminated significant benefit in the later multi-state experiment.

Before

Inspect fields and decide pesticide timing from experience, visible damage, or calendar practice. → Apply pesticide, sometimes before or after the economically effective pest threshold.

After

Checks pheromone traps weekly and uploads smartphone images. → Detects and counts pink bollworm moths and compares counts with an action threshold. → Receive a localized spray advisory and decide whether and how to apply treatment.

Human boundary

The model determines whether the observed count crosses an advisory threshold; farmers retain the pesticide application decision.

Why it matters

Farmers can spray against a shared trap-count threshold instead of a calendar or subjective visual assessment.

Every step, actor, and control

Exception path

Farmers and extension partners can withhold treatment, inspect manually, or use other integrated-pest-management methods; rainfall and low pest pressure can make the advisory produce no measurable benefit.

Work removed

  • Subjective manual moth counting for every participating farmer
  • Some prophylactic or mistimed pesticide applications

Decision authority

The model determines whether the observed count crosses an advisory threshold; farmers retain the pesticide application decision.

Work that left the path

  • Subjective manual moth counting for every participating farmer
  • Some prophylactic or mistimed pesticide applications

Human role before

Farmers individually diagnosed pest pressure and timed spraying.

Human role after

A lead farmer supplies trap images; the model standardizes counting; farmers act on threshold advisories and still perform field work.

AI roleComputer-vision detection and counting of moths in pheromone-trap images used to trigger localized pest advisories.

Outcomes

Farmer income in initial field evaluations

Verified

Non-adopter or control farmers in 2020-2021 evaluation locationsUp to 22% higher income in the first-year evaluations; no significant benefit in the 2021-2022 multi-state experiment

2020-2022 · Initial evaluations in Ranebennur and Wardha followed by a seven-state experiment

The mixed evidence is essential: early evaluations were not all randomized, and unusually high rainfall with low pest pressure eliminated significant benefit in the later multi-state experiment.

What leaders can reuse

Anti-pattern

Promoting the 22% first-year result without the later null result or ignoring the labor required to inspect traps.
