ADVANTAGES OF BT COTTON —
a. BT cotton successfully repels the boll weevil larvae, one of the pests of cotton plants, and other larval insects that harm the plant; eliminating the necessity for pesticides.
b. There are no potentially physical health hazards, while in the form of semi fabrics or raw material.
DISADVANTAGES OF BT COTTON —
1. We don't know the consequences of inserting the BT gene into the cotton gene pool.
2. Since it affects all larval insects, there are chances that beneficial caterpillars in the area will be killed too.
3. Famous cotton based firms like Monsanto might put special crop seeds out of the reach of developing countries, who may require them to protect already-polluted groundwater, environment, etc.
4. It is ecologically a hectic task to cultivate such a crop, due to its need of pesticides for 8-10 times in a single season (to get a decent yield). This requires a tractor, and subsequently its fuel as well as the farmer's time and money.
5. It poisons the groundwater and is a health hazard to humans and other organisms.
