Why the HT Cotton is gaining popularity 1 It is largely grown in hydroponic culture 2 It is a natura...........

Explanation:

Statement 3: In normal cotton, spraying of herbicide is not possible once the plant has emerged out of the soil, as the chemical cannot distinguish between weeds and the crop itself.
But with cotton that is genetically engineered to ‘tolerate’ herbicide application – through introduction of another alien gene, this time coding for a protein inhibiting the action of that chemical – only the weeds, not the crop, get killed.
Statement 1: Hydroponics involve growing crops in a nutrient rich water medium. This is not the case with this variety of cotton. It is grown on land.
Learning: However, as the unapproved cotton variety is claimed to be herbicide tolerant, farmers resort to indiscriminate use of glyphosate, a herbicide, causing health hazards to humans and
cattle, apart from affecting the yield of cotton.
The herbicide-resistant gene could spread through pollen into the biodiversity system leading to transformation of weeds into super weeds on a large-scale.
It would not only threaten the growth and yields of all crops in future, but also could increase cultivation costs and lead to health hazards
