Hi, anyone have any ideas how to save money with respect to fungicides for collar rot, specifically, Subdue Maxx and Ridomil? I don’t want to spend hundreds of dollars for a gallon of either, and I am not sure I even need a smaller container. I just want to drench no more than about six trees, so I am thinking I only need what, an ounce or two, and the appropriate amount of water. I am open to any ideas or related thoughts on this. Thanks for your assistance.

I feel that once you start you are going to have to do it continually so maybe you should get the 5gallon that is on sale.
My advice is to find out why they got sick to begin with and fix that after disposing of the infected plants.

Plant some new plants, esp a different cultivar/species/family.

Make sure you do not stress the plant unnaturally.

Welcome to permies Kip
The only times I've seen collar rot, it's caused by one or more of these: planted too deep, waterlogged soil, mulch right up to the stem.
These are all cultural issues that can be fixed by changing planting/amending/mulching practices.
Fungicides are generally extremely hard on soil life, and I don't use them.

I'm with Leila that these problems only occur when trees are improperly planted or maintained.

What type of trees are these? How are they planted or grown?

Avoid the fungicides at all costs.

Delightfully ironic; making a fungal-rich AACT for foliage spraying works as a powerful probiotic
