Fungicide program/plan

Post by 7474 » Wed Mar 13, 2019 6:02 pm

NE Ohio, lawn has been crushed by fungus the past 2 years. Planning the following this upcoming year.....

All at preventative rates.....

Week 1 Azoxy
Week 2 Propiconazole
week 3 TM 4.5 Thiophanate-methyl
Week 4 Propiconazole

Starting in May, repeat as needed.

Thanks for any feedback.

Way too many fungicides too quickly.

May 1: Azoxy lasts 28 days
June 1: Propiconazole lasts 14 days
June 15: Thiophanate lasts 14 days

July 1: repeat :thumbup:

I agree with @MassHole , but aside from the timing, the rotation of those three fungicides is what I use. I mix azoxy with propi for the first two apps, 28 days apart and then rotate to the T-methyl. Repeat. Seems to work. It’s expensive.

For when to start / stop, the Syngenta and Cornell forecast maps are pretty good.

Yes, this would be very expensive especially for my yard. I'm going to spray propiconazle and azoxystrobin ONLY when the green cast tool show the pressure is high for a fungus.

Careful with propiconazole on Bermuda.

Why? What's wrong with spraying it on Bermuda? I haven't read anything on the label about it. I may have missed something I will read it again.

The low preventative rate for all. Brown patch or dollar spot rate.

Bermudagrass can be sensitive to PROPICONAZOLE 14.3 SELECT. Do not exceed 4 fl. oz. per 1,000 ft2 every 30 days on any
variety of bermudagrass. In Florida, do not apply PROPICONAZOLE 14.3 SELECT to bermudagrass golf course greens when
temperatures exceed 90°F.
