I’m not saying you shouldn’t use RoundUp. It is great for dealing with poison ivy and hard to weed spots, but everything in moderation and RoundUp and other herbicides containing atrazine should be used in extreme moderation.
A common weedkiller in the U.S., already suspected of causing sexual abnormalities in frogs and fish, has now been found to alter hormonal signaling in human cells, scientists from the University of California San Francisco (UCSF) report.
. . . It was banned in Europe after studies linked the chemical to endocrine disruptions in fish and amphibians. . .
In studies with human placental cells in culture, the UCSF scientists found that atrazine increased the activity of a gene associated with abnormal human birth weight when over-expressed in the placenta. [read more Common herbacide disrupts human hormone activity in cell studies]
And more bad news on the chemical end of gardening: Fertilizer prices are drastically climbing.
In part because of a global surge in demand, the price of fertilizer has skyrocketed 228 percent since 2000, forcing U.S. farmers to switch crops, cut back on fertilizer or search for manure as a substitute.
Wholesalers and retailers are scrambling to find and buy fertilizer and juggle what supplies they have to meet customers’ needs. Between 2001 and 2006, global demand jumped 14 percent, an amount equivalent to the entire U.S. market, according to The Fertilizer Institute, a Washington D.C.-based trade group.
