Can Celsius be used in combination with Prodiamine preemergent?

Answer:

In general, it is fine to mix a pre-emergent herbicide like Prodiamine 65 WDG and a post-emergent herbicide as long as neither product label prohibits this mixture. Be sure you use the correct rates for each product. We also recommend a small jar test for compatibility before mixing a larger tank. You also will need to activate the Prodiamine with irrigation or rainfall after at least 24 hours but within 14 days of the application, per the product label.
 
The Celsius WG Herbicide label states the following: If this product is to be tank-mixed with other products, compatibility should be tested prior to mixing. To test for compatibility, use a small container and mix a small amount (0.5 to 1 qt) of spray, combining all ingredients in the same ratio as the anticipated use. If any indications of physical incompatibility develop (precipitation, settling, changes in color), do not use this mixture for spraying. Indications of incompatibility may occur within 5-15 minutes after mixing. Please be sure to review the product labels of both products for more information and complete instructions before use.
