Jerry from Davenport Fl writes

Directions say to apply Hi-Yield Atrazine Weed Killer when temp is under 90. What about after application?

Is it safe to apply if temp goes above 90 say 4 hours after application?

Answer:

Hi-Yield Atrazine Weed Killer can be applied early in the morning before temperatures reach 90 degrees if it's expected to get this hot on the day of application.  You just do not want to apply during the time of high temperature because your desirable turfgrass is under more stress in high heat.
