Chemical/Non Organic Fungicide Thread

[wis99ski]

3" of rain this week with humidity +90% I'm grateful I dropped heritage before I saw any issues 2 weeks ago. This is the rainiest late spring into summer that I can remember. May had lawns starting to go dormant. This is the first year with my blueberry, bewitched, prosperity reno and its holding up well so far with all this water.

So far this year I've had Powdery Mildew (early spring), then Dollar Spot (early summer), then Leaf Spot (now). The Powdery Mildew and Dollar Spot problems went away, but the leaf spot is taking its toll. Some parts of the lawn look great, others are suffering.

Im probably too late this year for any type of preventative or curative, but I want to plan for next year.

Seems like Heritage is the way to go, but it's expensive. I have a backpack sprayer so can use granular or liquids. Whats the cheapest preventative fungicide for leaf spot? TY.

Oh and I would like to use a Biological Fungicide if possible.

  Whats the cheapest preventative fungicide for leaf spot?

I don't know if its the cheapest but if you are going to be using it for a few years and you have square footage to cover propiconazole can be had in gallons for under 100. Typical app rate is 2oz per 1000.

Ok thanks. Im going to stick to biofungicides first to see how they perform.

Looks like 1 gallon = $88

And there it goes, off topic, even though the title does say "Chemical/Non Organic Fungicide".

After reading over this thread, I see that Daconil is a popular fungicide however, every product I've found on the web that contains the active ingredient (Chlorothalonil) explicitly states that it should not be used on residential lawns. It can be used on golf courses, corporate landscapes, flowers, fruits, etc....but not in residential lawns. For that very reason, I have never used it. Anyone know why it's not labeled for residential use?

Applying chemicals scares me to death but I realize that it's necessary evil in order to maintain the lawn that I desire.

Here's a clipping I have on the subject in my database:

Use for home lawns
Chlorothalonil is no longer labeled for use on home lawns. While this restriction has been in place for several years, it is such an important one that it is worth revisiting. Prior to the institution of this restriction, chlorothalonil was probably the No. 1 fungicide used on residential lawns. This restriction was agreed to by manufacturers of chlorothalonil in order to reduce overall exposure of two populations to the active ingredient: toddlers exposed after the application on home lawns, and residential handlers and applicators of chlorothalonil on home lawns. Keep in mind that chlorothalonil is registered for disease control on a variety of crops, including food crops. In order to reduce overall exposure to chlorothalonil in these populations and be in compliance with the Food Quality Protection Act, manufacturers agreed to voluntarily remove home lawn uses from the label.

Chlorothalonil is a Group B2 "probable human carcinogen", based on observations of cancers and tumors of the kidneys and forestomachs in laboratory animals

Welp, that settles it for me. This is exactly why chemicals scare me.

Never...EVER will I be using Daconil on my lawn - nor on my vegetables, for that matter.

Andy, thank you for saving my life...and my kidneys!

If you are concerned that Dac is going to kill you, then you should never, ever get in a motorized vehicle.

[andy10917]

Why is that, McLovin?

[Leifcat1]

If you are concerned that Dac is going to kill you, then you should never, ever get in a motorized vehicle.

I understand the risks associated with being in a motorized vehicle and I willingly accept them. On the other hand, if a product table states that it shouldn't be used in residential areas due to the fact that the active ingredient might cause tumors, I'm unwilling to accept that risk. I'm just a guy that likes to follow product labels whenever possible.

I realize that plenty of people use Daconil and are alive and well. More power to them. But I choose to avoid anything that could be a danger to myself or my family.

I even thoroughly vetted the risks associated with Milorganite before applying it for the first time. There are plenty of conspiracy theorists that believe Milorganite is toxic. But until the label says that it's not labeled for residential use, I'll continue to use it. But beingst that this is a thread about non-organic fungicides, that's all I'll say about that.

Great chart, thanks. I see Propiconazole doesnt work for leaf spot, but it works for melting out? How come?

Put down Thiophanate Methyl only on the side front about 2 weeks ago, due to a few small patches of browning grass with lesions (some of which was definitely brown patch). It appears to have stopped it in its tracks and the patches are starting to recover now. Not sure if I'll follow-up with another dose of fungicide or not. The weather is supposed to be cooler for the next few days. Like last year, glad I used the fungicide before it got too bad.
