Its hard to say just where this resistance came from, if it was overuse from LCO or not. The latest research pins triazine resistance squarely on overuse in the LCO business, but I suppose the case could be made that these chemistries aren't solely used in LCO."
Your sites say there are resistant weeds. We all l one that!
Where is the data that states it STARTED due to LCO's?
Also you state there have been "loads of weeds" resistant to 3 way products. What are those weeds?
You say the latest research say trizene resistance started in turf. Where is that data? Trizenes are used on almost every corn acre.
Again I know resistance is a problem but asking you to support your comment on being started by LCO's.
