News: Recently, demand for Bollgard-3 in Punjab has increased ahead of the cotton sowing season.
About Bollgard 3
- This genetically modified (GM) cotton variety is resistant to pests and was developed by Monsanto over a decade ago. It demonstrates exceptional resistance to insect attacks.
- The variety incorporates three Bt proteins—Cry1Ac, Cry2Ab, and Vip3A—which disrupt the gut function of pests, ultimately leading to their death. This, in turn, promotes healthier cotton growth and enhances yield.
- Farmers are advocating for the introduction of Bollgard-3, which is particularly effective against lepidopteran pests such as the pink bollworm.
- Monsanto first introduced Bt cotton in India with Bollgard-1 in 2002, followed by Bollgard-2 in 2006, which continues to be widely used today.
Key Benefits of Bollgard 3
- The three proteins in Bollgard 3—Cry1Ac, Cry2Ab, and Vip3A—each eliminate larvae in unique ways, providing effective control of Helicoverpa armigera and Helicoverpa puntigera throughout most of the cotton season.
- The reduced need for broad-spectrum pesticide applications helps preserve beneficial insect populations, promoting a more balanced ecosystem.
- Compared to conventional cotton varieties, Bollgard 3 plants exhibit significantly higher first-position fruit retention on the bottom five fruiting branches. Retaining these early fruits is crucial, as their loss can lead to substantial yield reductions.
