When I sprayed my pepper and tomato plants, I basically sprayed until the water was running off of the plants. Based on the Natural Industries website, the more Actinovate a person applies, the better. If cost isn't a major concern, you could possibly try using a heavier dose per gallon of water (for example a 1/2 tsp. as opposed to 1/4 tsp.). I'm not saying this will necessarily work in your area, but the Natural Industries website would seem to suggest your chances of success would improve with a heavier dosage, and it might be worth while to do a small trial with a more concentrated spray to see if it has any impact or not. The one thing that really stood out to me was how Actinovate seems to stimulate plant growth (I guess by improving the plants ability to intake nutrients from the soil). In my previous post I mentioned my pepper plants. For my tomato plants, I typically prune all of the leaves off up to the lowest set of fruit. Therefore, at the end of the season, the bottom 5 - 6 ft. of my plant will just be the main stems. When I sprayed with Actinovate, I noticed a lot of plant regrowth on this bottom 5 - 6 ft. (similar to my sweet pepper plants). In particular, my Sarnowski Polish Plum plant not only re-grew, but also set a large number of tomatoes. As a first time user of Actinovate, I was probably more impressed with this aspect of the product than its ability to minimize diseases. |

Mark, there is a lot of scientific evidence that supports your experience that Actinovate stimulates plant growth. Although not all Actinobacteria produce the same antifungal and antibacterial metabolites that Streptomyces lydicus WYEC 108 does, it seems they may all produce the plant growth promoting metabolites indole-3-acetic acid, ACC deaminase and also siderophores which are iron chelating compounds that can be taken up in plant roots.

I found Actinovate locally last Friday at a hydroponics store. Finally had a chance to mix up a small amount of it today and sprayed it on all the foliage of my plants.
I happened to notice that Ray N. said he couldnt find it locally. That was three years ago, but Ray, if you happen to read this, I see there is a hydroponics store with several locations in the Bay Area, most of them north of you, but HydroDepot.com shows they are $16 for the 2 oz size, and if you can save the shipping, it's better than the $30 you mentioned a while back. I'm uncertain about how to do a soil drench on plants that have been planted out. Just soak the ground around the stem, or does it have to be applied directly to the root when planted? |

You'll be fine with the soil drench, those little microscopic spores will filter down to the root zone through any reasonably loose soil.
I've bought Actinovate from the hydrotoyou store on EBAY, they sell the 2oz packet for $16.49 or 2 for $29.99 - free shipping. Fresh product too. |

Great, any idea how much to apply per plant, approximately?

2 grams per gallon of water (or 1/2 teaspoon) is the recommended rate for the Actinovate solution, both for soil application and foliar spray. |

If you are going to do a soil drench with Actinovate the addition of MycoGrow soluable and Biota Max can add to the effectiveness with additional fungi and bacteria and to overall plant health. The ideal regimen would to apply as a root dip during plant out.
Phosphorous Acid has been shown to be effective against bacterial wilt and spot and can be applied with Actinovate as a foliar. Exel LG is one such product along with Agri Fos. Ami

thanks! Ami, I will have to look for those other products.
Ray, thanks also. I mixed up only a small amount, same proportion but 1/4 tsp to a mere 2 quarts water, because I didn't have a big sealable container and wanted to use as a foliar spray. I have done a little pour of maybe 1/3 cup over each root in the raised bed and a few other newly planted plants. I figured I could always mix up more tomorrow. |

By the way, it is Act-i-NO-vate, isn't it? Stress on the third syllable? I asked the guy in the shop where I bought it and he wasn't certain either. I thought Ac-TIN-o-vate sounded, well, tinny.

Huh. Wrong again! Well, I'll be sure to say it correctly, if it comes up in conversation. Thanks!

I have bacterial wilt in my soil, where do you find the chemicals and how do you use them, in the soil or as a plant spray, quite new a raising tomatoes, Larry

Some people claim various manure teas are helpful against bacterial wilt, but as far as I know, none are confirmed. The only real solution is make your soil as healthy as possible, and rotate crops religiously (at least 3 years without any tomatoes or solenaceous crops), always disposing of tomato vines either by burning, or "hot" composting. Either that or containers. Someone else around here might know of a solution, but I never heard of one. PS I heard somewhere that "Neptune" and "Tropic Boy" are somewhat resistant. There may be a few others, not sure.

Redbaron is right that Actinovate has not been shown to be effective against bacterial wilt. It's more antagonistic against fungal pathogens.
The most effective biological control at combating bacterial wilt that has been studied is Pseudomonas fluorescens. P fluorescens is included in some Myco/bacterial inoculants like Great White and the Alpha Bio Thrive products. |

Here are some suggestions by the University of Florida that provide some level of control of Bacterial Wilt (Ralstonia solanacearum).
Grow Host resistance varieties. Graft seedling onto resistance root stock. Application of Phosphorous Acid (Exel LG or Agri-Fos) also as a foliar. Soil Solarization And as RayR said use "Myco/bacterial inoculants" on plant out. For anybody that has soil disease problems I would highly recommend growing you plants in containers whether it be the open type or SWC's (Self Watering Containers). Ami
