As of 2015, 26 plant species have been genetically modified and approved for commercial release in at least one country. Whereas, herbicide tolerance is the inherent ability of a species to survive and reproduce after herbicide treatment at a normal use rate. 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. Scientists have produced plants that are resistant to herbicides. -Mars's orbit could be perpendicular to Jupiter's orbit. Herbicide resistance is the ability, trait, or quality of a population of plants within a species or larger taxon, or of plant cells in culture, to withstand a particular herbicide at a dosage that is substantially greater than the wild type of that plant is able to withstand, with a near normal life cycle.

A weed population herbicide-resistant weeds often referred to as superweeds are nuisance plants have. It is believed that within any population of weeds, a few . Resistance happens with the repeated use of the same herbicide, or herbicides with similar modes of action on a weed population. The genetically engineered proteins can be produced in large quantities with less cost. Currently, about 180 weed species (more than 300 weed biotypes) worldwide are resistant to about ten different herbicide families. The most common herbicide tolerant (HT) crops are known as Roundup Ready, meaning they are .
