Old, new products deliver multi-modes of action

The challenge is to hit weeds with two or more active ingredients to reduce resistance

By
Old chemistry, new formulations, multiple modes of action — these are all elements farmers can include in their weed control toolbox heading into 2017, say weed researchers and crop protection specialists. One of the most important elements these days for either preventing or managing herbicide resistance in weeds is to approach control with multiple modes […] Read more
Weed researchers are studying several options to control herbicide-resistant weeds. Researchers need to test each product or practice alone, and in combination.

Stem Shock: new herbicide in development

A new mode of action based on RNA could soon be killing a weed near you

By
It’s been over 20 years since chemical companies released a new mode of action in herbicides. But a B.C.-based company is cooking up a whole new type of herbicide. “We use a different mode of action for the actual killing of the plants than a lot of traditional herbicides. Most herbicides, by reducing the specific […] Read more
