So what is the favorite brand of Horticultural oil to use for figs for dormancy/winter storage?  Does it matter or are they all the same thing?
 
I usually make the stuff with vegetable oil or Neem oil and liquid hand soap. 

1 cup of oil.
1 tablespoon of soap

Mix 2 tablespoons of mixture into 2 cups of water in spray bottle and shake well.
 
I've has good success with Monterey Horticultural Oil - Organic Gardening Fungicide, Insecticide, & Miticide - Controls Aphids, Mites, Scales. My main problems are scale and bud mites.
 
The highest purity mineral oil that you can get is the best one.  Fewer other chemicals to affect your trees. The bonide linked above is what I've bought instead of getting a gallons (lifetime x2,3,4 supply) of the really pure stuff.

I've not seen negative effects applying this with sulfur after leaf drop.  I've had mite issues before that we're treated during the growing season, but I now apply oil and sulfur before packing up each fall and I've not seen them reoccur.  Surely I'll bring some in again at some point and hopefully summer sulfur and spinosad will be sufficient, but this is the dormant season's answer for me.
 
@"DCallahan"#71 @"RedRockFig"#125 @"hambones"#63 . I never thought I would consider horticultural oil when Azamax, and Azatrol were available. I just never have been a fan of Horticultural, and Neem. Still I had a big struggle with (FBM) fig bud mites. My original cuttings had several apical buds that came in infected with them, and I was fighting for control all spring, and summer. It makes perfect sense to employ sulfur with neem oil during the dormant months.

BTW is there a recommended amount of sulfur to ad add to the Neem oil per gallon? Also would I be using wettable sulfur, or some other form?
 
There is no difference as the brands.  If you go to garden center, any brand should work.  It is mineral oil.  Can store for a very long time.  

It is highly recommended to use it in early spring, to kill insect eggs etc.
 
I'll pass what Fruitnut (possibly the most knowledgeable figger we have) told me when I had problems with scale and bud mites. For scale, Spray dormant trees with Hort oil, twice in the winter, with applications 1 month apart. For bud mites, spray when trees start bud out and leaf out for bud mites. Spot spray again whenever you see a break out of bud mites. You can also use soluble sulfur spray if the bud mites aren't controlled with Hort oil.
