A new biocontrol agent to manage ‘foot rot’ disease in Basmati crop: Why this matters?

  • Recently , The Punjab Agricultural University (PAU), Ludhiana, has developed biocontrol agent “Trichoderma Asperellum”  to combat ‘foot rot’ disease in Basmati Varieties of Rice.

Foot Rot Disease:

  • It is also known as Bakanae disease.
  • Causative Agent: ‘Fusarium verticillioides’
  • It is a soil-seed borne pathogen which spreads the infection through the root of the plant, and eventually leads to the colonization of the stem base.
  • It affects Basmati rice crops particularly at the seedling stage, though it might also cause infection after transplantation in case infected seedlings are transplanted.
  • Symptoms : Infected seedlings first turn pale yellow, then elongate and dry up, and eventually (usually) die.

Preventive Management Strategies to Control Foot Rot Disease:

  • To prevent the disease from occurring and spreading, farmers resort to
  • Early seedling treatment,
  • Try to use disease-free seeds, and
  • Destroy infected seedlings.

Timely seed nursery management :

  • Seed sowing in the first fortnight of June, and transplantation in July.
  • Sowing in May often leads to problems as the month’s high temperatures are favourable to the disease.
  • Well Drained Fields : Fields where the nursery is being set up must also be well-drained, with proper irrigation, to avoid the spread of foot rot.

Current Practices :

  • Seedlings are treated with ‘Trichoderma harzianum’ before sowing and transplantation.
  • Seeds are also treated with fungicides such as Sprint 75 WS (carbendazim + mancozeb) before sowing.
  • But these are the chemical treatments which are harmful for the soil, and can be toxic for consumers of the rice.

Importance of New Biocontrol Agent  ‘Trichoderma Asperellum’:

  • It is an important development in rice farming techniques, bringing in a more sustainable strategy that will offer a non-chemical alternative to traditional pesticides.
  • This transition ensures safer rice production, aligning with global standards for food safety.
  • It will help in aiding in disease management while minimizing environmental harm.

Basmati Rice:

  • Basmati rice is a long-grain aromatic rice known for its extra-long slender grains, fluffy texture, delightful taste, superior aroma, and distinct flavor.
  • Varieties of Basmati Rice: Around 34 varieties recognized under the Seeds Act, 1966.
  • Cultivation Areas: Only Permitted to cultivate in J&K, Himachal Pradesh, Punjab, Haryana, Delhi, Uttarakhand, and western Uttar Pradesh.
  • It is a registered GI (geographical indication) product.
  • Largest Producer & Export Leader: India is the top exporter, around 70% of global production.
