I suppose that, the first question is,
Is there a crop response on soybean fungicide application at least 75% of the time?
Seems like it would need to be at least 75% of the time to be a break even situation.
Then the next question would be.
What is the average ROI on soybean fungicide?
1) When applied on time, IIRC it is recommended at 5/16” pods in the top few nodes?
2) When applied 1 week later?
3) When applied 2 weeks later?
