It is, but it is expensive. I've been using XENTARI since it became available through this forum. Much, much cheaper to use. One bottle of Certan is mixed with 19 parts water using the bottle as a measure. 1/4 TBS of XENTARI makes a similar amount. The Certan cost me over $20 with shipping for a bottle; the XENTARI cost me just over $30 for a pound. The Certain makes enough liquid to treat about 120 frames, a 1/4 TBS of XENTARI will treat the same amount of frames.
I had my amounts wrong for mixing. It is one tablespoon per quart.
To the best of my knowledge the reason BT401 is no longer available in the US is because the demand for the product did not warrant renewal of the licenses or whatever is required to continue sales of such products. I imagine there are also costs associated with testing and labeling a product for additional uses. The demand for a such a product from beekeepers evidently doesn't warrant the expense to to this either. In the meantime, to the best of my knowledge the products use the same bacteria, XENTARI is approved for use on a large amount of food products, it kills the heck out of wax moth larva and using Certan in the US is just as wrong as using XENTARI.
Don't get me wrong, it works great. I had some supers of drawn comb in storage for about 22 years that was treated with certan (use to get it from Kelley's) and were just perfect went I remembered where they were tucked away in my mom's garage. I had two sheets of newspaper between each box and it was dated 1988.
The mix rate is one teaspoon per quart of water, not tablespoon
The following is the reply for Certan 401
The label is not online.
B401 is the only formulated larvaecide against wax moth. Will not harm you, your honey or bees. It is mixed at 19-1 and lightly sprayed with a pump up sprayer on the frames, will cover 120 frames.
Can I see the label on-line, if not will you answer the following questions?
Is Certan - B401 labeled for use in living bee colonies?...Yes, but used on frames in storage not on live bees.
Mixed at 1 to 19, how many drawn frames can be treated?....120
Does this mean 1 bottle to 19 bottles it's same size?...Yes
Do you mist or saturate the frames?... Lightly mist.
Does B401 come in larger size containers?...No
Is it a liquid or powder?... Liquid
What is the shelf life after it is mixed?..unlimited
Well Joseph thank you for all your help in answering the question!! I found it last night when i used the google search...Its not BT Certan B401...Its not Certain B401...Its just B401! Again Thanks Joseph for your help!
