They collected more than a million seeds from the plants, growing them into seedlings to test for herbicide resistance and doing genetic tests.

Soybeans engineered with herbicide resistance have encouraged no-till farming that reduces soil erosion, water pollution and costs.

Occasionally, researchers wish to transfer more than one trait (e.g. an insect resistance and a herbicide resistance) to a crop.

In 2006, farmers associations were reporting 103 biotypes of weeds within 63 weed species with herbicide resistance.

Many things are blamed for poor blackgrass control and there is a growing tendency to condemn herbicide resistance.

So, if you still feel herbicide resistance is to blame, this is the season to test for it.

When genetic engineers slip a gene for herbicide resistance into a crop, they hope that the domesticated plants won't pass it around.

Nonengineered plants with a mutant gene for herbicide resistance showed nowhere near the level of erosion of family values.

The environmental effects of cocoa production, such as herbicide resistance and deforestation are becoming much more severe as demand for cocoa increases in present day.

This was in part, the agency said, because the implanted gene conferring herbicide resistance was harmless to people and livestock.
