Abstract
Resistance of crops to herbicides through biotechnological techniques has got immense application towards convenient, flexible, and efficient weed management. Herbicide-resistant crops (HRCs) are designed to tolerate specific broad-spectrum herbicides which kill all the associated weeds without injuring the cultivated crops. HRCs allow farmers to more effectively use reduced or zero tillage cultural practices, eliminate the use of toxic herbicides and allow the use of fewer herbicides to manage the entire spectrum of weeds. But in India, Bt cotton is the only permitted transgenic crop for commercial cultivation. The major benefits associated with HRCs include: broad-spectrum weed control, reduced crop injury, cost-saving, yield advantage. However, the long-term impact of HRCs on biodiversity, the environment, and human health has yet to be fully understood. This article attempts to provide an insight into the challenges and opportunities of the adoption of HRCs.
