How does roundup ready seed work

Glyphosate, the active agent in Roundup, was first discovered to be an herbicide in by Monsanto chemist, John Franz. At that time in the ag industry, most herbicides were pre-emergent, meaning they were applied before the crop and weeds emerged. The post-emergent activity of glyphosate in controlling a large number of broadleaf and grass weeds was very different, which when combined with its exceptional environmental soil inactivation, rapid degradation, no carryover, etc and toxicological properties extremely low toxicity to mammals and beneficial organisms , made it a breakthrough product.

It was initially used in ditches, on railroads and sprayed on fields between growing seasons. This allowed farmers to control grass and broadleaf weeds that emerged from the soil, thus decreasing the need for tillage, preserving soil structure and reducing soil erosion.

By the early s, this team had developed the first systems to introduce specific genes into plants and our attention shifted to developing virus -resistant, insect resistant and Roundup-tolerant crops.

By the mids, our researchers had identified both plant and microbial genes that conferred increased herbicide tolerance in laboratory tests and in the USDA approved the first field test of Roundup Ready plants. Bayer has utilised gene technology to insert two genes which make Roundup Ready canola plants tolerant to applications of glyphosate:. Bayer partner with leading canola seed companies to ensure Roundup Ready canola is available in high-performing varieties.

Why Are Plant Hybrids Sterile? Kinds of Seed Plants. Differences Between Biomass and Biofuel. Interesting Facts About the Hackberry Tree. Harmful Effects of the Green Revolution. Types of Genetic Crosses. Roundup is the brand-name of a herbicide produced by Monsanto. Its active ingredient glyphosate was patented in the s.

Roundup is widely used by both people in their backyards and farmers in their fields. Roundup Ready plants are resistant to Roundup, so farmers that plant these seeds must use Roundup to keep other weeds from growing in their fields.

The first Roundup Ready crops were developed in , with the introduction of genetically modified soybeans that are resistant to Roundup.
