    Propiconazole Fungicide

    By Dana on 06/07/2017

    There are two types of grass fungicide: systemic fungicides that are absorbed into the plant, and "blockers" that prevent fungus spores from invading the plant. Propiconazole is a systemic fungicide, and appears to be working just fine. However, you should switch to another fungicide "every other time" to prevent the disease from developing resistance. By the way, customer service at DoMyOwn is five stars+.

    Wish I didn't hesitate

    By Tim on 08/31/2017

    I had rust all over my new 1+ acre lawn planted early June 2017. Most everything you read online says to just fertilize and it will go away, it did not for me. As soon as I put this stuff on it killed the rust and the lawn was growing again in two days. I wish I just bought it and applied as soon as I noticed the rust as it was really bothersome to me for almost a month.

    Worked exactly as described

    By Nathan on 08/14/2017

    Used this product for dollar spot and brown patch. Used with Docket WS Fungicide and then alternated to Quali-Pro TM 4.5 two weeks later. I have had zero activity since I started rotating these products.

How long should Propiconazole 14.3 be applied before rain?


It is recommended to water in herbicide and fungicide products like Propiconazole 14.3 because typically they need to get down to the root system, and the main way to do this is to water the lawn so the product can make its way to the roots.  You can also apply more water when performing the treatment for the same effect. If you apply the product before a rain event, that is even better.

How much Propiconazole 14.3 do I need per gallon of water for brown patch?

The mixing rate of Propiconazole 14.3 is 1-2 fl. oz. per 1000 square feet.  This would be mixed in however much water it takes to cover that 1000 sq. ft.  Generally 1-2 gallons will cover the area but this depends on the specific equipment being used, how fast you are walking, and the pressure of the sprayer.
