The main objective of the production/use of herbicide-resistant GM crops is to:
Correct answer: B. Reduce herbicide accumulation in food articles for health safety
- A. Encourage ecofriendly herbicides
- B. Reduce herbicide accumulation in food articles for health safety
- C. Eliminate weeds from the field without the use of manual labour
- D. Eliminate weeds from the field without the use of herbicides.
Explanation
Genetic engineering has helped to develop such transgenic crop plants which are resistant to herbicides so that they are not damaged when farmers spray herbicides in the fields. Herbicide resistant plants have been developed in such a way that they continue to produce normal crop yield and at the same time remain unaffected by the activity of herbicides. These plants also reduces the use of weeding labour, farmer's cost and increases yield.
