Re: Apple-Crop: Dodine and captane fungicides applied during bloom
Thanks. I had heard mention of this as a possible factor in Colony Collapse Disorder - and it seems plausible since contaminated pollen can be stored for a long time. A lot of beekeepers are blaming neo-nics, while the manufacturers stoutly claim it's not so. Whatever the case, farmers should be aware that some beekeepers are refusing to place bees on pollination where neo-nics are used. -All good reason to keep in open conversation with your beekeeper(s).

Re: Apple-Crop: Dodine and captane fungicides applied during bloom
Interesting article, but I'd like to see the peer-reviewed research. Nearly every statement in the article contains weazel words or wording that implies uncertainty (e.g., which SUGGESTED the sprays were toxic, the solutions COULD be more toxic, etc.). Very few of the ideas in the article come across as proven facts, although that might reflect the writing style of the author. I've become a bit skeptical of popular articles about bee problems because, in the barrage of early articles on Colony Collapse Disorder, beekeepers almost always blamed pesticides whereas later research either vindicated pesticides or listed them as only one among many contributing factors.

Re: Apple-Crop: Dodine and captane fungicides applied during bloom
Here's a good article on how pesticides accumulate in pollen. The authors don't claim to understand how the pesticides may impact the bees, but report on how much they're finding.There's another article from J. Econ. Ent. that talks about solitary bee foraging. http://www.plosone.org/article/info%3Adoi%2F10.1371%2Fjournal.pone.0009754 Mullin, CA (Mullin, Christopher A.); Frazier, M (Frazier, Maryann); Frazier, JL (Frazier, James L.); Ashcraft, S (Ashcraft, Sara); Simonds, R (Simonds, Roger); vanEngelsdorp, D (vanEngelsdorp, Dennis); Pettis, JS (Pettis, Jeffery S.)

RE: Apple-Crop: Dodine and captane fungicides applied during bloom
Hello all, If I remember correctly, the work that I saw showing reduced pollen germination due to captan was done in vitro (in test tube). Having said that, Mancozeb performed much better than Captan in such tests, and if I need to spray for scab during peak flowering, I often opt to use Mancozeb. However, on continental Europe use of Captan during flowering is commonplace.
