- As per the recommendation of the Genetic Engineering Approval Committee (G.E.A.C.) of the Government of India, the total B.T. 20 percent of the area or 5 rows of non-BT of the same variety around the main crop. Planting Non-BT seed (Refugia) is very important.
- Every BT variety has non-BT seeds (120 gm seeds) or Pigeon Pea seed comes with the same packet.
- BT variety plants contain the genes of a Bacillus thuringiensis, which produces a toxic protein. Due to this, they develop the ability to protect against bollworm insects.
- The infestation of bollworm insects is limited to them, and their control is easy here.
- If the Refugia is not applied, the resistance of bollworm insects may develop, in which case the BT varieties will no longer make sense.
