So its been very humid, wet, and hot. I need to throw down a fungicide, i have heritage df and propiconazole but it rained the past 2 days total of 5 inches. Starting to see signs of diseases. What would be a good plan of attack? Should i wait for soil to dry? Also i have some liquid merit i need to get down stat. Any advice would be much appreciated!
Apply fungicide and or pesticide after a heavy rain???

Since you would spray both, they would have the quickest effect if foliarly absorbed. I would wait until you have a 12 hour window without rain to spray them. I wouldn't be concerned about the soil being wet. I would combine them and spray. Combined, you can cut the rate in half and use essentially a preventive rate of each but as a curative. This would be rolling your own headway fungicide. Also, with 2 MOA's, you'll have the best chance of success unless you are positive with your fungus ID.
