Can Celsius be sprayed at 85 degrees even the temperature is rising and will be above that in an hour or two? In other words can I spray in the morning when it is 75 degrees and an hour later the temperature is over 85 degrees?
As long as the temperature during the application of the Celsius is not 85 degrees or above, then it does not matter what temperature it reaches mid day. The best time to apply herbicides is either early morning when dew is still fresh on the ground or late afternoon when the lawn and weeds are under less stress from the environment. The less stress the weeds are under the better they will absorb the product being used.
