New ‘Green’ Pesticides Under Development

Exploiting a little-known punch/counterpunch strategy in the ongoing battle between disease-causing fungi and crop plants, scientists in Canada are reporting development of a new class of “green” fungicides that could provide a safer, more environmentally-friendly alternative to conventional fungicides. They will report on the first pesticides to capitalize on this unique defensive strategy here today at the 237th National Meeting of the American Chemical Society.
Developed with sustainable agriculture in mind, the new fungicides — called “paldoxins” — could still do the work of conventional pesticides, helping to protect corn, wheat and other crops. These crops increasingly are used not just for food, but to make biofuels. The new fungicides also could help fight the growing problem of resistance, in which plant pests shrug off fungicides, the researchers suggest. (more…)
