Pesticide Marketed As Safe For Bees Harms Them In Study
In the recent decade, people have started realizing the effects of pesticides on the surrounding environment, especially on the health of bees. The alarm rings only for so-called safe pesticides having neonicotinoids, neonics, which are also considered as safe for bees. But the truth needs no introduction. The substance, flupyradifurone (FPF), sold under the name of Sivanto, harms bees. According to a recent study published in Proceedings of the Royal Society B, FPF is not at all bee-safe if it comes in contact with Propiconazole (fungicide).
FPF Producer Pesticide Marketed Is Safe For Bees
On the website of FPF, it clearly states that it does not harm bees but the targeted insects. Adding to the statement, the Producer of FPF, Bayer said that the compound used in pesticides does not harm bees. Well, the above statement might be accurate, but only if flupyradifurone is used alone. Its after-effects haven’t been studied by the producing company when it comes in contact with fungicide, PRO (Propiconazole).
Together, both Flupyradifurone and Propiconazole will harm the mortality rate of bees by increasing it. Whether or not bees are foragers or residing in beehives, both will be adversely affected. Adding to this report, these compounds, if reacted, will also increase abnormal behaviors in bees such as lacking motor coordination and hyperactivity.
Scientists’ Stake On FPF (Flupyradifurone) And Its Bees Harms
Scientists have a significant concern about the safety of FPF, as it is similar to neonicotinoids. Neonicotinoids are a harmful classification of pesticides that harm the central nervous system (CNS) of insects. Although FPF not fully considered as neonicotinoids, yet as it is a very similar compound, it may have its effects.
According to Vera Krischik (a student of the University of Minnesota, studying Bumble Beesat), chemistry is systematic. As FPF shares the same features as neonicotinoids, it may harm bees by entering into nectar and pollen.
The Experiment Carried Out To Reveal The Harmful Effect Of Safe Pesticide Marketed
In the research carried out by a team studying bees behavior post-exposure of pesticides, they exposed bees to six levels of dosage of FPF. In each dose, FPF was about 375 to 12000 ng per bee. Apart from testing bees for FPF, they also exposed bees to PRO’s single dose, measuring 7000 ng per bee.
Upon exposure, researchers observed the bees’ mortality rate up to 48 hours and found, half of the bees exposed to FPF were able to tolerate the higher dose. Whereas half of the bees that exposed to FPF and PRO together could endure and died. The study showed that if only exposed to FPF (up to 1869 ng per bee), bees can endure before reaching 50% of mortality. But FPF, together with PRO, cannot be endured by bees. They would die.
Bees Harms: Pesticide Marketed Safely For Bees
If the pesticide has FPF, then it is not safe at all. It can react with PRO to increase the mortality of bees.
