Started off on a preventive program, but two outbreaks of dollarspot made me switch up my rotation a bit. I do not spray fungicide unless there is a risk of an outbreak based on the weather and the syngenta forecast maps. Here is what I have done so far
07/01: Azoxystrobin preventative rate
07/27: Outbreak of dollarspot, treated with Eagle 20W and Clearys
08/27: Preventative rates for azoxystrobin and Eagle 20
09/20: Preventative rate of Clearys, bad weather in the forecast.
Today: Outbreak of what appears like brown patch? This occured after 14 inches of rain over the period of 5 days. It has been a week since we have had sun in SE houston and temperatures are hovering in the 70s. Fungacide is all over my lawn.
My question is, do I rotate back to azoxystrobin for a curative rate, mix azoxystrobin and eagle 20 at preventative rates?
Any suggestions are welcomed. I am trying to prevent any type of resistance from building up.
Next year, I will be adding in a class 7 fungicide to help me manage dollarspot.
