Surprised that didn't work. Maybe a day or two late with spray. The bigget problem here is that all big cos. selling same 3 active families either FRAC 3, 7 or 11. FRAC 3 (DMI/triazole) is only family good on Fusarium. FRAC 11 makes it worse & FRAC 7 is weak. How long before resistance to FRAC 3? Only been around for 40 years!
This is reason why one might consider to add a contact oxidizer like OxiDate 5 to the tank. At 0.5-1% of spray volume costs $1.70 for 5 gls by aircraft or $2.70-5.40 in 15 gl/ac by ground. Mixes well with FRAC 3 products or 7 & 11.
Or just settle.
