What makes weed control easier when using genetically engineered crops?

• A. Crops that are resistant to glyphosate
• B. Crops that require more manual labor
• C. Crops that are grown in larger quantities
• D. Crops that are native to the region

Answer: (A)

The effectiveness of weed control is greatly enhanced with crops that are resistant to glyphosate. Glyphosate is a widely used herbicide that targets a broad spectrum of weeds without harming the genetically modified crops that possess this resistance. This allows farmers to apply the herbicide directly to the fields without worrying about damaging their crops, leading to more efficient weed management and lower costs for weed control. Additionally, the ability to control weeds effectively can contribute to higher crop yields as it reduces competition for nutrients, water, and light. The other options do not provide the same level of benefit for weed control. Crops that require more manual labor would typically lead to increased operational costs and effort, making weed management more challenging. Growing crops in larger quantities does not inherently simplify weed control; in fact, it may even complicate it if proper management practices are not in place. Similarly, while native crops might possess certain environmental advantages, they do not generally offer the same specific resistance to common herbicides like glyphosate, which is what makes the control of weeds easier in the context of genetically engineered crops.
