One solution is the rotation of crops resistant to different herbicides, or rotation of herbicide use with use of other weed control strategies. Notably, the ALS gene, ACCase gene, and EPSPS gene have provided a wealth of potential genes to produce herbicide-resistant crops.. What is glyphosate resistance gene? Pesticides = Insect Resistant Herbicides = Weed resistant. With the repeated use of the same herbicide, there is a greater increase in the percentage of resistant weeds . The same four crops that have been modified for herbicide resistance have also been modified for insect resistance using the Bt toxin. Melissa_Kindelspire TEACHER. As a result, there is a small increase in the percentage of resistant plants in Year 2.

One of the more common criticisms leveled against Genetically Engineered plants, particularly Herbicide-Resistant (HR) strains, is that they are purported to lead to what critics refer to as "Superweeds.". Herbicide resistance refers to the ability of plants to evolve resistance to herbicides. 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. 9 How do transgenic bacteria produce insulin?

Increase of herbicide-resistant biotypes. The first modern herbicide, 2,4-D, was first discovered and synthesized by W. G. Templeman at Imperial Chemical Industries. Because herbicides tend to affect plants more quickly and severely than animals, the most useful biological sign of herbicides is effects on aquatic plants (Kreutzweiser et al.
