When did crops become resistant to herbicides? Insect-resistant crops contain genes from the soil bacterium Bacillus thuringiensis (Bt). For thousands of years, humans have used breeding methods to modify organisms. If the "volunteer" is an herbicide-resistant variety, the herbicides that could control it might be more toxic or expensive than the glyphosate that is usually used.

Crops do not damage the environment simply because they are GM. If the same herbicide is applied once again, there will be little seed produced by the susceptible plants, but the resistant plants will continue to set seed. It is a specific type of drug resistance. Sage Automotive Spartanburg, Sc, These problems are similar for non-GM and GM crops.
