A mature pineapple plant carries a 1.5 to 2.5 kg fruit on a slender peduncle above a shallow root system. Strong winds during fruit development topple fruiting plants and snap peduncles, especially on the tallest MD2 hybrids. Lodging losses are highest just before harvest, when yield is at maximum but the plant is at its most top-heavy. Regional priority: High on exposed coastal blocks, cyclone or typhoon paths, and highland ridges. Moderate elsewhere.

​
When pineapple is most vulnerable

From fruit set (month 15) through harvest (month 22). Vegetative plants can withstand strong wind with limited damage; fruiting plants cannot.

​
How wind damage shows in satellite data

  • Sudden localized NDVI drop after a storm event in exposed rows.
  • Pattern follows wind direction and topography (windward slopes and gap zones).
  • Best confirmed by post-storm drone flight; Sentinel-scale imagery misses individual toppled plants.

​
Field symptoms

  • Tipped-over fruiting plants, root plate lifted
  • Snapped peduncles with fruit lying on the mulch
  • Bruised, torn, or shredded leaves on the windward side
  • Clustered damage on outer rows, headlands, and gap zones
  • Fruit contamination with mud and mulch fragments (post-harvest quality risk)

​
Reduce the damage by

  • Establish windbreaks on exposed blocks - Leucaena, Gliricidia, or bamboo hedges perpendicular to prevailing wind.
  • Support fruiting plants with stakes or peduncle ties on high-value MD2 blocks.
  • Choose shorter-statured varieties on wind-exposed sites (Sarawak / Moris) rather than tall hybrids.
  • Time harvest before the peak wind or cyclone season where possible.
  • Post-storm triage - within 48 hours, harvest fruit that has fallen on the mulch (still marketable) before rot sets in.
  • Avoid excessive N in late vegetative - lush, tall plants lodge more easily.

​
Set an alert for early warning

Turn the diagnosis into a trigger. Wind is a weather event, so build the alert on wind-speed forecasts, not NDVI.
Recommended settings for wind on pineapple:
  • Weather alert - forecast wind speed above 50 km/h during fruit development or ripening.
  • Cyclone / typhoon warning - trigger a post-storm scouting dispatch on any block within the projected path.
  • NDVI post-storm alert - trigger on a 0.10 or greater block NDVI drop within 48 hours of a wind event.
