The Weed Science Society of America ranked Palmer amaranth as the most troublesome weed in the U.S., while Galium was determine the most troublesome weed in Canada.

A study published in the journal Weed Science found cotton yield loss was reduced from 67% to under 30% when weed establishment was delayed until 6 weeks after crop planting.

Researchers today are transforming weed control with new precision tools and application techniques that can keep herbicides precisely where they belong. As a result, farmers are able to optimize the performance of herbicides and minimize the small amounts that drift off target as they are being applied.
