Using FGMO

[Oxankle]

I need to check signals here with other FGMO foggers.

I am surprised by the amount of oil I am using. I have now made and used about 4 litres of FGMO/thymol since spring.

Method; Five seconds, sometimes seven, of fog in front of each hive. I am fogging (now) l7 hives once weekly, occasionaly a second fogging in the week.

Having read posts stating that little oil is used I am concerned that (1) I am administering too much fog or that (1) the orifice on my fogger is putting out far too large droplets and so using more oil than it should.

I have been concerned that the orifices on the Burgess foggers were plastic and perhaps not uniform. However, on examination they seem to be steel and so would probably be pretty uniform, either drilled or broached.

Anyone care to comment on the oil usage?

Hi Ox
I use fgmo too I am doing about 150 in one yard with a 16oz. bottle mineral oil with about 15 seconds in each hive. doing it every week. sounds like you might be useing too much or it must be dripping a lot on the ground.
sounds like your propane is not getting it hot.

The manufacturers for the Burgess model 1443 propane fogger have printed on their carton 1-2 oz.for 1000 cu.ft.Pump stroke delivery was one of a number of tests I perfomed on the above model and found this to be under 2 mls per stroke.Exact delivery over repetitve strokes was 1.875 mls per pump stroke in my test and uniform.The coil and shroud were non magnetic confirming they were stainless where as the nozzle was magnetic proving to be steel.My quick calculations suggests to me that the amount of oil used by OX is excessive for that number of hives for fogging alone.I have not stated the delivery test proceedure here as if not done correctly will cause severe carbon build up in the coil.

Thanks, Fellows:

I will go back to the drawing board and see if I can do better. I suspect that Beeman may have a point as I notice a dropoff on fog delivery after two strokes of the pump.

An earlier poster suggested that I may need a heat shield around the stainless mesh when I noted that wind seemed to be cooling the coils. I'm going to try that and see if it improves the fog delivery.

I have 18 hives and I use about a pint a month, with 2 applications per week. I hope this helps. The fog seems to be working ok. I now am having another problem with my fogger. It won't stay lit. I have called the manufacture on this and they are sending me a new fogger. It can get frustrating trying to use it and not enough heat coming out. Anyone else having this problem?

Dan, I had that happen to me only when the tank was getting low JJ

My tank is still 3/4 full. I think it might be the flame need to be adjusted and that is what the manufacture thinks too. They are sending me a new one. Nice of them.

I cheat.
I carry a propane torch in my other hand and superheat the coil for less down time.
Seems to work well, and use less oil.
