How long before a rain is Ranger Pro safe to apply?
The product label for Ranger Pro Herbicide does not specify a certain amount of time but it does say that heavy rain soon after application may require a repeat application. The word soon is open for debate, but we would recommend only applying the product when you have a good 3-4 days of no rain in the forecast. 3-4 days of the product being dry should be enough for it to do the job.
