Climate stress and pests shrink mango harvest in north India
Heat stress during flowering and unseasonal humidity have led to a widespread decline in mango yields this season, despite a promising bloom in many orchards. Observations from Suresh Pal in Kheri district and reports from the Terai region indicate pests and diseases worsened fruit set, with desi varieties showing some resilience and popular hybrids potentially facing shortages and higher prices.
Why It Matters
Mango production is a major agricultural and market concern; a shortfall can affect both farmers and consumers through potential price increases and reduced availability in summer markets.

Observation of withered 'baur' on 35 mango trees in Bhangaiyachat village
May 2, 2026
Suresh Pal of Bhangaiyachat village in Nighasan tehsil, Kheri district, reports that all 35 mango trees in his orchard bore a rich blossom this season, but the 'baur' (blossom) withered and darkened instead of setting fruit. This observation is described as part of a broader pattern across mango belts in the Terai region and north India, where an initially promising bloom largely failed due to unusual climate changes. Agro-scientist Dr Pradeep Kumar Bisen notes that a sudden rise in temperatures during flowering caused heat stress, compounded by unseasonal humidity from untimely rain, storms, and hail that created favorable conditions for pests like mango hoppers and diseases such as powdery mildew, thus disrupting pollination and nutrient flow to blossoms. He also observed that indigenous or 'desi' mango varieties showed relatively better resilience, with examples from Baharganj village in Bankeyganj area where a desi tree bore fruit while many hybrids failed.
