found White mold in my soybeans pics

I was scouting my soybean fields today, noticed that the aphids are lightening up, I don't think I will need to spray for them at all. I did however find this plant with white mold on it. Not a huge surprise as I have a great recipe for it. Narrow rows, 140k population and tall beans that canopied early. Now, what to do about it. Beans are just finishing up flowering, pods are established and beans are just starting to form. I believe this is the R5 stage. I had a consultant from the local co-op out, he suggests spraying them for the white mold, didn't tell me what product they would put on but did say it would cost me $32/acre to have them apply it. Now, I only have 50 acres of beans, but these 50 acres of beans are my entire crop for this year and they look great, I wanna save what I have, but $32 x 50 acres = $1600. Thats alot of money, so I started thinking a bit about options...

I could just have them spray the lower areas of each field which might be the places where white mold will be the worst. This could probably get me down to treating less than 20 acres. This idea could save me about $1,000. Is this thought reasonable? or is the higher ground likely to get mold if the mold is already in the lower areas of the same field. They are there anyway, would it be smarter to just have them spray the whole field? or does partial spraying make sense?

The field rep also suggested spraying some foliar fertilizer in the same pass as the white mold treatment. Have you tried any folior fertilizers at all? I'm not sure what I think of them, they seem like snake oil but I have no experience with them and don't know anyone who has.

I'd be real interested in any of your thoughts on treating this white mold issue.

Other thoughts to consider...

I do have my own sprayer, 30' boom (co-op has 120')
My tractors have 18.4 inch rubber, my beans are in 14" rows, not sure what the co-op has for tire width.
I do not have a license to purchase restricted use pesticides.
I am willing to spend some money here, so long as it is justified and will likely yield a return

I appreciate all thoughts and will let you know what I decide to do after meeting with my crop rep tomorrow. Thanks!

Once the disease is present and you are seeing infected plants, it is generally considered too late for a fungicide to provide much benefit. In addition to the cost of the material and the application fee, consider the amount of beans that will be tramped. I am in an area that is very prone to white mold. I applied Acapela fungicide at the R 2.5 stage as a preventive, combined w/ .5 gallon/A of a foliar, plus Assist. Infection and severity will depend a lot on weather conditions the next month. if it is hot and dry, you likely will be spared , but if it is cool and damp the losses can be severe (foggy mornings seem to be the worst) The odd brown plant will turn into a patch and the patches will continue to get bigger. Rain and wind will move the spores across the field. Good luck.

I got some of that white mold in my basement. You can smell the stuff being very musty. Spray with a mix of water and Clorox. I am going to try of a mix with Clorox and a little copper sulfate. Will see if this mix works even better. I know it is not in the field,, just throwing out some thing that worked.

I'd forget trying to get them to spray bits and pieces of the field that's a waste of time.

I would go ahead and spray them and would put in a foliar fertilizer depending on what it is. They could do a tissue sample to see if you have any glaring deficiencies.
