A study
in the recent issue of the journal Outlooks on Pesticide Management
reports that there are now 15 weed species that have complete resistance
to the world’s most widely used herbicide, Monsanto’s glyphosate. Researchers
say most of these "superweeds" have developed resistance over
time, due to long-term overuse of the chemical. Glyphosate, most commonly
applied as Monsanto’s Roundup, has been in heavy use globally for over
30 years. The study warns these superweeds pose "serious"
problems to farmers if new control strategies are not developed. Of
course the best way to avoid spawning superweeds is to ban genetically
engineered crops and to adopt organic farming practices. /old_articles/ge/superweed081905.cfm
