Carl from Texas writes

I applied Tenacity when temperatures were 79 degrees and later in the day, temperatures reached 93 degrees. Will Tenacity lose its effectiveness due to the spike in temperature?

Answer:

If the Tenacity Herbicide application had enough time to completely dry before the temperatures spiked to 93 degrres, there shouldn’t be any issues. It is recommended to apply Tenacity when temperatures are between 65 to 85 degrees so early morning or late evening applications may work best if temperatures above 85 degrees during the day are expected. If any yellowing or discoloration occurs, the turf should recover after a couple weeks.
