Fungicide combos

11 years ago

For those of you who mix your fungicides together, using two at the same time, do you still use the ratio of that fungicide to water as stated on the container? Or do you mix it weaker because you're using two fungicides?

I use tebuconazole (Bayer). It just took one extremely warm day (88 degrees) and a cool night for a fungal outbreak to start up on a couple of roses. I want to try mixing it with mancozeb, but don't want to make the chemical mix too strong.

I've never mixed two fungicides together but I would think that if you are mixing each separately at the proper ratio and then mixing the two together they would be OK.

Yes, you still need to keep the proper ratio for each fungicide. If you are great at math, you can probably mix them in one container at one time. I would have to use seil's method. I have enough trouble figuring out how to mix one. I used to have a certain measuring cup and marks on my sprayer and now I'm using a different product and I have to start from scratch....
