I’m trying to learn more about biologicals and the relationship (if any) to southern rust and tar spot.
Any thoughts?
For rust and biologicals, if you have rust, I would spend time researching the disease and not a product.
If rust is present there is nothing a biological is going to do. If you spray a biological on the leaf it's going to interact with the leaf in the way biology does, colonize and compete for food and space. but it's not a fungicide, it's not interfering with the rust feeding on the leaf.
Rust and the other pathogens being as harmful as they are is the results of farming in a system that doesn't build strong healthy plants. And a product in furrow can't fix a system.
We are back to the same conversation of farming in a more biological system to defend against a biological enemy.
There is absolutely a direct correlation between soil health and plant health. When we are doing several passes of fungicide and insecticide, we need to fix the soil before we can fix the plant.
How does full tillage, front loading fertilizer, using many passes of biocides on fragile soil effect plant health
Take them questions to Google or AI and ask for research papers. Happy reading!
