Can we mix T-Nex PGR, Bifen XTS(insecticide) and Propocanazol 14.3(fungicide) into a tank sprayer and apply this to a Bermuda lawn?

If i apply at the suggested rates for each chemical will there be any stress to the lawn with all three applied at the same time? Also will there be any negative affects to the chemicals from mixing them?

When unsure if mixing chemicals are compatible you should perform a jar test.

However, I'm fairly certain you can mix those and they will be compatible.

You might see some injury from propiconazole but it will recover just fine.

Per the label on propiconazole 14.3:

"Bermudagrass can be sensitive to Quali-Pro Propiconazole 14.3. Do not exceed 4 fl. oz. per 1000 sq. ft. every 30 days on any variety of bermudagrass. In Florida, do not apply Quali-Pro Propiconazole 14.3 to bermudagrass golf course greens when temperatures exceed 90°F."

Yeah I wouldn't put the propiconazole in the mix. Do that first and see if their is damage from it. I mixed propiconazole and tnex before and it over suppressed my lawn and didnt grow out of the over suppression for a long time. Better yet dont use propiconazole at all.
Which mode do you use for disease control if not propiconazole? I try to switch it up every 3 weeks or so but its one I do use and didn't notice any issues.

Is the insecticide for an issue or just a preventative? If the latter, I wouldn't even put it down. If correcting an Issue I would do it separate.

It is my thoughts.

1. Both Propiconazole and TNex are systemic products. I would think the grass blades can only absorb so much. I'm probably wrong.
2. Do both require the same amount of water per 1k?

Good thing I checked with you guys, I didn't know Propiconazole is not that good for Burmuda lawns.
