Can you mix propiconazole with Daconcil for plantings at my residence....which includes zinnias, iris, and various perennials , gardenias, and other shrubs.
If yes, how much Daconcil and propiconazole would be used per gallon?
George on Apr 14, 2016
BEST ANSWER: Hi George, You can use Daconil with Propiconazole to help prevent fungus resistance. It gives you two modes of action so if one doesnt kill it then the other will. You would use 1/2oz of propiconazole and 2oz of chlorothalonil 720 per gallon. If you use another chlorothalonil product then you would switch the mix rate accordingly. We just sell a lot of the 720 so i gave you that mix rate.

so far non effective. My brown/dying grass areas are growing and double the dosage or more (4oz /1/2 gallon) of the product had no effect

Potent and Effective
Purchased propiconazole two weeks ago so that I could control the brown patch that infested my front lawn. The propiconazole nipped the fungus in its tracks. I then removed the dead grass and began the reseeding. The seedlings are now appearing and the fungus up to now has not reappeared. I plan on applying additional propiconazole in the middle of August and then once again prior to the first snow at the end of October.
