This item is not very convenient to use. It has to be diluted and they only give instructions for making one gallon of the formula. Using less means doing calculations and measuring very carefully. I sprayed a few plants that appeared to have spots and some moldy growth, fungus like growth on them. It took two applications spread over a period of days to see any results. I'm still not sure that it has rid the plants of the mold/fungus but the plant with the spots is looking much healthier. I think another application may be needed on my herbs that have survived so far ( most of them gradually were overcome by the mold growth and died). The ones that showed signs of having this mold and were treated by this liquid seem to be surviving at least and may even recover. So using this at least prevented their speedy demise, but I still might need to spray again to make sure the problem is solved. Sorry this is not any more precise, but I really am not a gardener and it is amazing any plants survive me. Bottom line, the treated plants are still alive so that is a win.

Every year I struggle with powdery mildew on my peonies and bee balm plants, so I was jazzed to give this organic concentrate from Arber a go. And so far, I am absolutely seeing improvements with this issue after several sprays! I love that this is a more natural alternative—plus, bee-friendly! 🐝 This product is VERY concentrated, so be sure to consult the dilution guide on the bottle. It barely looks like I’ve used any, so I expect this will last a long time. Once the concentrate is mixed (and shaken, of course) with water, you’ll wanna make sure to use it all up as this will not keep. I tend to err on the side of making a little less so I don’t end up wasting it.

Last year my squash and tomato plants all suffered from some sort of blight. I bought some very expensive liquid that was designed to protect the plants. I think it worked, but only on the newer leaves. I got a harvest, but not much of one.

This year I was looking for something different and when I saw this Arber Bio Protectant from the Arber Store, I ordered it. It’s a 5% solution of an extract of Reynoutria Sachalinensis, a useful invasive plant from the Far East (Japan and Russia). It’s a pretty amazing plant with it being grown for animal feed (not usually), as an energy crop for biomas production and to produce this extract which is useful as a protectant against certain fungal and bacterial infections.

The directions say that you should mix two Tablespoons of this concentrate with one gallon of water and pray that on your plants. I talked with an expert with this material and he told me that I should make sure to use whatever I make within two days as the water you mix it with will degrade the compound and make it ineffective. If you use distilled water it will last a bit longer (according to this expert). It will last fine unmixed in the bottle.

So I’m making it up a pint at a time. I haven’t yet had the opportunity to use it on my plants as they haven’t been planted yet, but I will, right from the start. You can spray this material on your plants right up to the day you harvest them. That’s a very good thing! This is probably ten times cheaper than the stuff I used…
