Chemical Poisoning


In modern agriculture, chemical agents are used to protect plants from diseases and pests, but some of them can be dangerous for bees.

Farmers are obligated to inform beekeepers in advance of any plans to spray or pollinate plants, so that beekeepers can take necessary measures to protect their bees.

When beekeepers are informed of spraying or dusting plans, they should close the hive early in the morning before the bees start flying, and open ventilation devices as much as possible.

If bees need to be closed for an extended period, they should be given water in the feeder or empty honeycomb. In hot weather, bees should be moved to a cooler room until the danger has passed, and then returned to their original location, ensuring each hive is in its proper place to avoid confusion and damage.

While hives are closed, bees should not be disturbed or fed. The length of time bees need to be closed depends on the type of chemical used and the duration of its toxicity.

  • The effects of arsenic and fluorine preparations last for three to five days
  • The effects of parathyroid preparations cease after three days
  • Nicotine agents, herbicides, mineral oils, and similar agents are only toxic to bees for a few hours after application

If heavy rain falls after spraying or dusting, the danger to bees is greatly reduced. Additionally, strong winds or high temperatures, over 30 °C, can help reduce the danger to bees.

Beekeepers should establish direct communication with farmers, local municipalities, chambers, and associations to find the best solutions for protecting both plants and bees. Without constant communication and cooperation, it will be difficult to achieve favorable results in protecting bees from chemical plant protection products.
