Super Weeds: Another Reason Why Organic Farming is the Solution - Page 2
Agricultural experts said the use of other chemicals is already creeping up. Monsanto and other companies are developing new seeds designed to resist older, more environmentally toxic herbicides like dicamba and 2,4-D, a weed killer developed during World War II and an ingredient in Agent Orange, which was used to destroy jungle foliage during the Vietnam War and is blamed for health problems among veterans.
Penn State University weed scientist David Mortensen estimates that in three or four years, farmers' use of dicamba and 2,4-D will increase by 55.1 million pounds a year because of resistance to Roundup. That would push both far up the list of herbicides heavily used by farmers.
Dicamba and 2,4-D both easily drift beyond the areas where they're sprayed, making them a threat to neighboring crops and wild plants, Mortensen said. That, in turn, could also threaten wildlife.
All the above is very bad news. Why? Scientists might be able to produce herbicide resistant crops so that extremely poisonous chemicals can be used to kill weeds, but humans, wildlife, and the ecology are NOT resistant to environmental degradation.
Besides, it's only a matter of time before weeds will evolve further to resist even the most toxic herbicides. What will we do then when human lives and the earth are heavily polluted with toxic chemicals?
Organic farming removes the need for toxic herbicides. Ask any organic farmer and he or she will tell you that the most potent tools against weeds are healthy soil, compost, and manual labor of tilling and weeding, all of which won't pollute and contaminate the entire ecology for generations to come.
