Detailed explanation-1: -HRCs have a great potential in the simplification of weed management. Handled judiciously, these crops may be beneficial to the environment by enabling no-till systems, thus reducing erosion or allowing for later weed control, which may increase biodiversity in the field.
Detailed explanation-2: -Farmers can use less spray pesticides when they plant GMO crops. This saves farmers money and reduces the amount of pesticides that end up on crops. When farmers use herbicide-tolerant crops, they reduce the need to till the soil to control weeds.
Detailed explanation-3: -Final Answer: Main objective of production/use of herbicide resistant GM crops is to reduce herbicide accumulation in food articles for health safety.
Detailed explanation-4: -Herbicide-resistant maize, canola, cotton and soybean accounted for 77% of the GM crop hectares in 2001. However, sugarbeet, wheat, and as many as 14 other crops have transgenic herbicide-resistant cultivars that may be commercially available in the near future.
Detailed explanation-5: -Herbicide Tolerance (HT) helps farmers in better weed management. It helps the farmer to kill all the unwanted plants that compete with the crop in the cultivated field, thereby providing excellent control of the weeds and saving yields.
