I just hope its round up and not Furadan. Furadan is used on sweet corn and is deadly to bees. I've had dead hives from this.
The last I knew, you couldn't get Furadan anymore here in the US. (Unfortunately) The liquid Furadan is super great on *****. Fill a McDonald's cup with cat food, and dribble just a little bit of Furadan on the cat food. Stir it up good with a stick. A mean old tough **** will make it 5 or 6 feet. The wimpy ***** die with their head in the cat food.
The granular Furadan was a purple crystal. When you were spreading it, by the time you made a lap around the field and made it back to where you started, you would have dead birds laying everywhere.
Now you know why they outlawed it.
Normally bees won't mess with field corn pollen. Sometimes they will go for sweet corn pollen.
