Behind the Monsanto Deal, Doubts About the GMO Revolution

A l’origine les semences #OGM devaient nécessiter moins de pesticides et de logistique ce qui devait avoir pour résultat des grains plus sains et plus rentables.
C’est le contraire qui est vrai aujourd’hui.
Behind a wave of multibillion-dollar mergers in the agriculture business is a moment of change in American farming. The dominance of genetically modified crops is under threat.

Today, farmers are finding it harder to justify the high and often rising prices for modified, or GMO, seed, given the measly returns of the current farm economy. Spending on crop seeds has nearly quadrupled since 1996, when Monsanto Co. became the first of the companies to launch biotech varieties. Yet major crop prices have skidded lower for three years, and this year, many farmers stand to lose money.

Biotech farming has also shown limitations, given how certain weeds are evolving to resist sprays, forcing farmers to fork out for a broader array of chemicals. Some are starting to seek out old-fashioned seed, citing diminished returns from biotech bells and whistles.

The premise of biotech seeds was simple: Plants engineered to grow even while farmers applied a single, all-purpose herbicide to the field to attack weeds would let farmers buy fewer chemicals. Crops also secreting their own bug-killing toxins would reduce reliance on insecticides. Corn, soybean and cotton were natural markets, spanning tens of millions of acres in the U.S.
Monsanto and other seed companies could charge a premium for biotech seeds that were “Roundup Ready”—engineered to withstand Monsanto’s popular brand of herbicide—for those crops, splitting savings with farmers who would in theory save money spent on chemicals and labor.
