Celcius a Higher Degree of Weed Control
Safe for use year round on the most important
warm-season turf types
Celsius™ controls weeds at high temperatures,
allowing the turf to reach its optimal density during
the most favorable time of year for growing
warm-season grasses. There is no better weed
control than dense and healthy turf.
Unlike some other post-emergent herbicides,
LCOs can feel confident applying Celsius
because it is safe to use year round at high
temperatures on St. Augustine and centipede
turf without risk, damage, or fear of
Celsius is a post-emergent herbicide. With some
pre-emergent control, Celsius also allows turf to
release into areas where weeds once lived.
Newest generation post-emergent herbicide
Celsius features two new actives – iodosulfuronmethyl-
sodium and thiencarbazone-methyl – and
gives turf managers a new tool for managing
resistance to some existing post-emergent
Celsius has three use rates depending upon the
weeds that are to be controlled. The annual use rate
for weeds can vary from 2.5 - 4.9oz./acre in a single
application to a maximum use rate of 7.4 oz/acre
annually. Celsius uses 25-75 percent less active
ingredient than current post-emergent herbicides.
Exceptional control of broadleaf and grassy
weeds, application convenience, flexibility
Celsius controls more than 150 weeds including
many difficult-to-control broadleaf and grassy
weeds (see chart on reverse side for details).
Celsius is safe to use at high temperatures and
gives LCOs the freedom to make post-emergent
applications when it’s convenient for them.
The soil activity of Celsius provides a barrier of
control for up to 60 days after the application
For spot treatments only
For spot treatment applications, add the specified Celsius rate of 0.057- 0.113 oz. (1.6-3.2 grams) to
one gallon of water. Spray weeds to wet. One gallon of spray solution will treat up to 1,000 ft.2 Add
0.25% v/v of non-ionic surfactant (NIS) or methylated seed oil (MSO) in the spray solution.
Not all spoons are alike. In order to ensure proper use rate, the spoon should be tested and weighed first.
Use kitchen or cooking type measuring spoons. Use level teaspoon or tablespoon.
Low rate is 0.057 oz. or 1.6 grams per gallon water
Middle rate is 0.085 oz. or 2.4 grams per gallon water
High rate is 0.113 oz. or 3.2 grams per gallon water
