My friendly Hydroponics store person recommended treating cuttings with a dilute OxiDate 2.0 solution before trying to root them as a control for fungus infections. People here have recommended a 10% bleach solution, but he suggested that the Oxidate was more effective over a period of several days. The bleach was only good for a few hours. He also suggested it for treating pruners and recycled pots to prevent a spread of diseases as well as a soil drench. The active ingredients are Hydrogen Dioxide -27.1% and Peroxyacetic Acid -2.0%

I did a search here but didn't find this product specifically mentioned here. Has anyone tried it?

Directions:
"Pre-Plant Dip Treatment: Use OxiDate 2.0 for the control of damping-off, root disease and stem rot disease caused by Pythium, Phytophthora, Rhizoctonia, Fusarium or Thielaviopsis, on seeds, seedlings, bulbs, or cuttings. Remove dead or dying foliage prior to dipping.
1. Use a dilution of 1:100 or 64-fl. oz. OxiDate 2.0 per 50 gallons of water. 
2. Immerse plants or cuttings; remove and allow to drain. Do not rinse.
3. Excessive foaming or bubbling during the dipping process is an indication of high levels of disease contamination."

The clerk recommended mixing up a solution of 1 1/2- 2 tsps. per gallon.
I don't like the idea of a soil drench because that would kill off your friendly, helpful fungi as well, wouldn't it?

I think when they say "immerse plants" - i assume they mean dip the plant body, not the soil.  OxiDate is basically Hydrogen Peroxide and Acetic Acid - the two of them produces a strong oxidizer.

Mara, I haven't used this product. However, the bleach solution has been extremely effective in fighting mold. It has been a life saver.

Thanks smatthew, brianm, and alanmercieca, for your comments. It will be interesting to try something new. 

I was just checking the measurement math, and the suggestion of 1-2 teaspoons per gallon is not right, I think.

If the suggested dilution should be 1:100, and one gallon is equal to 128 oz., then 1/100th of that would be 1.26 oz.?

1 oz. = 2 Tablespoons, so 2 ½ Tablespoons per gallon would be about right, +/-, wouldn’t it? 

I wish there were more suggestions on garden product websites about how to measure smaller amounts of their products. Fifty gallons of water seems a bit much.

Interesting method!  Hopefully it works super well and it catches on. So far I just use a toothbrush scrub my utensils and cuttings with bleach water and anti-bacterial Dawn dish soap.  It does a good job preventing mold and fungus generally; however, occasionally there is a problem that shows up.  When I see a little mold/fuzzies show up on a cutting, I use a Q tip and H202 to wipe away the yuckies.  So far, so good.

I've used OxiDate and it works, but is very corrosive when undiluted.  I always wear safety glasses, long sleeves and gloves when handling the bottle.  A product that is safer, and in my opinion, more effective is Green-Shield.   http://betterplants.basf.us/products/related-documents/green-shield-disinfectant-&-algicide-sell-sheet.pdf  

I make a solution of 1 tablespoon Green-Shield per gallon of water, dip the cuttings then rinse with water.  I've had very good results compared to chlorine bleach.  I believe there are other brands of Quaternary Ammonium products on the market.  They might be available in smaller sizes than Green-Shield whose smallest size appears to be a gallon.

SuperMario1, Thanks for the suggestion of using a toothbrush and antibacterial soap. It's good to know that an antibacterial soap will also have an effect on fungus development as well as bacteria. 
Thanks Alan for your help with the math. I mixed up a half gallon batch today and used it on today's prunings. i skipped the safety stuff but was extra careful with the solution and it all poured, measured and mixed up easily. After a few hours the solution turned cloudy and I poured it down the drain. 
Thanks for the Green-Shield suggestion fignut. The directions for OxiDate said not to rinse with water, so I didn't. OxiDate 2.0 comes in a quart size from my local Hydroponics store, so is a little easier to use and store.
