Guys all of @Ian Banks previous posts have been spraying related. So if we are talking a paddock then boiling the jug and torching individual weeks aren't going to cut it. So could we please stick to answering the actual question rather then interpreting it 100 ways like a beekeeper would
Whilst I can't answer the question, I will provide a resource that might with a bit more digging
I’m just a little anti spray, as I’ve seen spray hive poisoning. The sticker agents aren’t that flash and often do more harm to the bees than the spray itself.
Spray before the bees get up so the spray dries or spray late when they’ve gone to bed. Mostly try not to spray bee friendly flowers in full sunlight when the bees are foraging, you’ll have grateful beekeepers.
