* Overly optimistic assumptions about transgenic crops that produce two or more Bt toxins active against the same pest can lead to inadequate strategies for delaying evolution of pest resistance
Strategies for delaying insect resistance to transgenic crops rely on assumptions that often are overly optimistic, a new study led by UA scientists shows. Published as an advance online publication by the journal Nature Biotechnology, the findings could improve management practices for current biotech crops and promote development of new varieties that are more effective and more durable.
New research from the University of Arizona has shown us yet another example of the many ways in which GMO-crops (genetically modified organisms) fail to live up to the hype.
In this case, the research found that the efficacy of pest control via GMO-use has been notably exaggerated — and that many assumptions about the technology/approach and its effectiveness against common pests simply don’t match up with reality. These assumptions have been “overly optimistic” — as the researchers put it.
SUMMARY: "American farmers in three states are suing seed giant Syngenta AG in billion-dollar lawsuits, alleging that the company harmed U.S. corn markets when it released a new genetically altered strain of corn that wasn’t approved by Chinese authorities. "

GM wheat developed by Monsanto was discovered on farmland in Eastern Oregon
EXCERPT: Soil Association Policy Director Peter Melchett said… "No one could possibly believe that GM crops would benefit English farmers when they see the extraordinary costs that GM brings in unwanted contamination. Only an ideological fixation on GM, disregarding economic realities and more modern and effective crop breeding technologies… can explain why some English farming organisations and politicians continue to promote this out of date and dangerous technology."
The cases challenge the company's release of a genetically modified corn seed that China had not approved for import.
DES MOINES -- Agrochemicals giant Syngenta is facing a growing number of lawsuits challenging its release of a genetically modified corn seed that China had not approved for import, with losses to farmers estimated to be at least $1 billion.
