If there was a marked reduction in milkweed in the meadow you mentioned, you would need to do some digging as to who owns the property adjacent to the field, and what, if any, herbicides may have been sprayed. Proving plant injury from herbicide drift can be challenging even when the incident ...
Herbicides are not the only tool available to landowners and the presentation will also cover biocontrol -- for six weed species there are natural enemy insects that can be released as a control element. Other options include mechanical controls such as grazing, burning, mowing, tilling, hand pulling ...

Fortunately, it's not a widespread issue in our state, and we work to keep it that way by using residual herbicides, either at planting or immediately after planting.”.
Professor Pratley said the adoption of allelopathic strategies didn't mean herbicides could be dispensed with altogether, but it did mean farmers could reduce the dependence on herbicides and make them last longer. “I am really worried. If you look at the data on the increase in herbicide resistance, there is ...
And 12% believed they had weeds that were resistant to HPPD inhibitor herbicides, compared to 4% in 2013. Farmers were also asked if they had changed their weed management program due to concern about herbicide-resistant weeds. A larger number of respondents had, with 77% acknowledging a ...

Drift issues have grabbed a lot of attention this year. Herbicide drift, in particular, can have a dramatic effect on your crops, and it naturally gets most of the attention when drift issues are discussed. Yet even insecticide, fungicide, or other spray material drift can create problems. Frankly, I consider any drift to ...
