so you are using 25 mg per liter 5 grams sounded like a lot- but my first figure of 100-gal would take 9.5 grams and .5 grams makes 5 gallon dont know much about liters and such ( you are using .5 grams arent you) i went through this when i treated so the recommended amount i came up with is from a supply catalog (i guess thats cheating
)any way your bees well be strong. RDY-B
RDY-B, oh brother, now you have me second guessing what the instructions mean. I am putting these instructions below my post again, only the amount part. It says that 25 grams of Fumagilan, base per litre of 2:1 syrup. But Fumagilan-b is a concentrated form of the antibiotic Fumagilan
, so not as much is required. If you still read some kind of different dosage than what I am reading, continue on with this talk.
The instructions indicated "5 grams" per 4 ltres, not .5 grams. I don't think I am reading the instructions incorrectly. Randy, I wonder what form of Fumagilan the supply catalogue was using. Maybe it is not the same identical product to what I have, maybe the amount of antibiotic used is different. I don't know. But I definitely read that 5 grams is to be used, not the .5 grams that you indicate
Instructions can be difficult to follow, I know I do have issues with instructions many times.
4 litre is almost 1 gallon, it is really exactly 3.8 litres to a gallon.
I have measured 5 grams on my digital scale, it is just over 2 teaspoons.
The following directions are taken directly off the instructions that came with the Fumagilan-B medication.DIRECTIONS: Medicated syrup is best prepared at a concentration of 25 mg Fumagilan base per lite of syrup, usually a 2:1 syrup (two parts of sugar to one part of water). Fumagilin-B may be dissolved in water or syrup at room temperature. For best results, heat the required amount of water to 35-50 degrees Celsius, then remove the heat source and add the Fumagilan-B and the sugar in that order
The prepare this concentration of medicated syrup, use the following chart:
165 ltr water + 330 kg sugar = 380 ltre syrup (95 gallons) + 454 g fumagilan-b
35 lt water + 69 kg sugar = 80 ltre syrup (20 gallons) + 96 g fumagilan-b
8.7 lt water + 17 kg sugar = 20 ltre syrup (5 gallons) + 24 g fumagilan-b
1.8 lt water + 3.8 kg sugar = 4 ltre syrup (1 gallon) + 5 g fumagilan-b (this is what I use for each of my own colonies)
I hope this has helped to clear up this little discussion we are having. Have a wonderful day, best of this great life we live. Cindi
