Biotech boosters love to go on and on about how GMO crops reduce pesticide use. But once again, reality intervenes.
One weed scientist, David Mortensen at Penn State University, said the government should restrict the use of herbicide-tolerant crops and impose a tax on biotech seeds to fund research and education programs.The resistant weeds cannot be killed by the sole use of glyphosate, the active ingredient in Roundup herbicide, which has become broadly popular with farmers with the advent more than a decade ago of soybeans, cotton, corn and other crops that are immune to the chemical. The weeds now infest about 11 million acres, a fivefold increase in three years, Mortensen said.
Thus requiring more and harsher pesticides.
