Actinovate-EXEL LG/Agri-fos Compatibility
I just received an e-mail from Boomer Cardinale concerning Actinovate and Phosphorous acid (EXEL LG/AGri-Fos) and this is what he said.
"We've done tank mix studies with Phosphorous acids and the Actinovate microbe is perfectly compatible." So if you want to apply Exel LG or Agri-Fos as a soil drench after already inoculating the soil with Actinovate it is safe to do so. And you should be able to apply Actinovate and Exel LG or Agri-fos together as a foliar spray if you so desire. And you compost tea brewers out there. If you want to add Actinovate to your brew do so after the brewing phase prior to application to the crops. Ami

Ami,
Thanks so much for relaying this information from Boomer. I want to do an Exel LG soil drench now, so the timing of the confirmation re: compatibility is great! Raybo |

Ami,
Thanks very much. Also Boomer replied to my PM and advised Actinovate has an 18-24 month shelf life, which I assume triggers the "use by" date on my package. Tom |

Tom, I also asked the question in case he forgot to get back to you and the reply I got was good for 12-18 months after the Use By date. Ami

Ami, thank you - nice to know!
Just picked up another pack of Actinovate a couple days ago, and will add some to my next spraying with the Exel. Btw, at what rate are you using the Exel as a foliar spray? My label gives a range of 2 tsp - 2 T per gallon for tomatoes, and so far I've been using 4 tsp / gallon. Spraying a few "control" beds with Daconil instead of the Exel, so I can compare the results. All the plants look good so far. |

Suze, Last year I used 1 T per gallon. Ami

Suze, speaking of Daconil, I'm still following your spray schedule you suggested to me a few years ago. I'm curious though, how concerned should I be about runoff from the Daconil affecting the Actinovate and other products that I've innoculated my plants with? I'm using Actinovate and Myco-Stim (made by same company as Excel LG). What do you think? Bubba |

Bubba, are you using Actinovate as a soil drench or do you use it as a foliar as well. Also if you didn't catch the link I posted in your thread on Early Blight here it is again. Ami

If you do some targeted Google searches, you might find some info on how those various products interact. |

The name has been changed from Daconil to Ortho Max Garden Disease Control and the label no longer has the "weather stick" logo, so I guess it rinses off more easily. I wonder if it's even still as effective. |

Here's a quote from a study I found concerning Daconil and Mycrobials. Ami
The effect of chlorothalonil on soil microbial populations and enzyme activities was investigated in a microcosm mimicing soil ecosystem. The results showed that the bacteria were inhibited significantly after the application of chlorothalonil, and then recovered at 21d; the effect of chlorothalonil on actinomycetes in soil was less than on bacteria, and the populations of actinomycetes recovered after 14d; however, no significant inhibition of fungi caused by the fungicide was observed. As long as you just spray the plant with minimal runoff you should be OK. Remember Daconil is a protectant and not a curative. EXEL LG from what I read is not effective against Early Blight but Actinovate is. I would not use Actinovate and Daconil at the same time but alternate the applications. A new product I came across that is effective against Early and Late blight is Regalia. It is derived from the giant knotweed plant. Problem is the minimum amount you can buy is 1gal and that goes for $69.00 from the manufacturer. Exel LG and Agri-Fos work on Late Blight and other diseases but not on early blight. So it depends on how much you are willing to spend for the protection of your plants. One final note on all the inquiries I made to different manufacturers concerning the effects of fungicides/insecticides on their myco products the more I learned that most don't know or have the expertise to answer the question. Boomer at Natural Industries was one of the few that gave me a definitive answer concerning Actinovate/EXEL LG compatibility. So when in doubt stagger your applications of mycos and insecticides/fungicides. And if using mycorrhizae I would not use any insecticide/fungicide product as a drench other than mycrobials. Ami

Thanks Ami,
Very clear decision-tree that you have laid out. Raybo |

Here's a study I came across yesterday. Found exel in combination with Serenade to be more effective than Exel alone in the control of bacterial wilt. Thymol was most effective it says, but don't know how good that would be for the Serenade if it's used. All treatments increased yield significantly; wonder if that's because of reduced disease pressure alone or a combination of lack of disease & vigor inducing qualities of the phosphite.
Thymol & Actigard used together reduced bacterial wilt & significantly increased yields. They found Exel combined with reduced copper plus mancozeb treatments as having the best results for bacterial spot. http://www.reeis.usda.gov/web/crispr...es/207620.html |
