Pink Bollworm Attack

  • 16 Sep 2024

In News:

Haryana has seen an overall fall in acreage under cotton cultivation to 4.76 lakh hectares (lh) this kharif season from 6.65 lh in 2023. This has been accompanied by an increase in the area under rice from 15.20 lh to an all-time-high of 16.44 lh in the state.

Key Details:

  • The reduction in the cotton area — also reported in neighbouring Rajasthan (from 7.91 lh to 5.13 lh) and Punjab (2.14 lh to 1 lh) — has been attributed mainly to PBW infestation.
  • In May-June this year, at the time of sowing, the price of kapas (raw unginned cotton) averaged Rs 6,700-6,800 per quintal in Haryana mandis. This was against the average Rs 11,100-11,200 per quintal two years ago.

Pink Bollworm (PBW) Infestation:

  • Impact: The pink bollworm has devastated cotton yields by attacking the bolls, which affects the weight and quality of the cotton. This pest has been particularly damaging since its appearance in 2017-18 and has caused significant losses in Haryana, Rajasthan, and Punjab.
  • Spread: PBW spreads through the air and infected crop residues, which harbor larvae and spread to future crops. This infestation has led to a dramatic decrease in cotton acreage.

The spread of pink bollworm

  • The pink bollworm first appeared in north India during the 2017-18 season in a few districts in Haryana and Punjab, primarily cultivating Bt cotton, and spread to Rajasthan by 2021.
  • PBW primarily spreads through the air. Residue of infected crops, often left by farmers on the field to be used as fuel, can also harbour PBW larvae which can then infect future crops. Infected cotton seeds are another reason behind the pest’s spread.

Economic Impacts:

  • Price Decline: The price of kapas (raw cotton) has dropped from Rs 11,100-11,200 per quintal to Rs 6,700-6,800, significantly impacting farmers’ profitability.
  • Farmer Losses: Farmers like Shyam Sundar have reported substantial losses due to low yields and poor quality, leading them to switch to more profitable and reliable crops like paddy and guar.

Transition to Paddy

Water Requirements:

  • Challenges: Paddy requires much more water compared to cotton. Farmers need to flood their fields, which is challenging in regions where groundwater is saline or limited.
  • Current Practices: Despite the increased water requirements, some farmers have transitioned to paddy due to its potentially better economic returns, especially when paddy prices are relatively high.

Monsoon and Irrigation:

  • Weather Dependence: The monsoon this year has been favorable, allowing some farmers to successfully grow paddy. However, reliance on monsoon and supplementary irrigation from tubewells is not sustainable in the long term.

Government and Expert Perspectives

Government Incentives:

  • Subsidies: The Haryana government is offering incentives for farmers switching to alternative crops and using water-saving techniques like direct seeding of paddy.
  • Support: While there is support available, the effectiveness and reach of these measures are mixed, and some farmers have faced issues with insurance claims and financial aid.

Expert Opinions:

  • Temporary Solution: Experts caution that while switching to paddy may be a temporary solution, it is not sustainable long-term due to water scarcity and environmental concerns.
  • Environmental Impact: Paddy cultivation contributes to higher carbon and methane emissions, which adds to the environmental challenges in the region.

Economic and Industry Implications

Cotton Industry Concerns:

  • Reduced Production: Lower cotton production affects the entire supply chain, from textile manufacturers to cottonseed oil and meal producers.
  • Potential Recovery: There is hope that reduced PBW infestation this year may lead to a recovery in cotton yields, but the extent of this recovery remains uncertain.
