Question

Main objective of production/use of herbicide resistant GM crops is

• A. Eliminate weeds from the field without the use of manual labour.
• B. Eliminate weeds from the field without the use of herbicides.
• C. Encourage eco-friendly herbicides.
• D. Reduce herbicide accumulation in articles for health safety.

Answer 1

The correct option is D Reduce herbicide accumulation in articles for health safety.

Crops made resistant to herbicides by biotechnology are being widely adopted in various parts of the world. Those containing transgenes that impart resistance to post-emergence, non-selective herbicides such as glyphosate and glufosinate will have a major impact. These products allow the farmer to more effectively use reduced or no-tillage cultural practices, eliminate the use of some of the more environmentally suspect herbicides and use fewer herbicides to manage nearly the entire spectrum of weed species. In some cases, non-selective herbicides used with herbicide-resistant crops reduce plant pathogen problems because of the chemicals' toxicity to certain microbes Herbicide-tolerant crops can be produced by either insertion of a "foreign" gene (transgene) from another organism into a crop, or by regenerating herbicide tolerant mutants from existing crop germplasm. Biotech crops reached 160 million hectares, up 12 million hectares on 8% growth, from 2010 and 94 fold increase in hectarage from 1.7 million hectares in 1996 to 160 million hectares in 2011, makes biotech crops the fastest adopted crop technology in the history of modern agriculture.

So, the correct option is 'Option D, Reduce herbicide accumulation in articles for health safety.'.
