Explanation

Bollgard I and Bollgard II are brand names for genetically modified (GM) cotton varieties developed by Monsanto. These technologies involve inserting genes from the bacterium *Bacillus thuringiensis* (Bt) into the cotton plant's genome. These genes enable the cotton plant to produce proteins that are toxic to certain lepidopteran insect pests, particularly the cotton bollworm, thereby making the plant insect-resistant. This reduces the need for chemical pesticides.
