Doris from Weldon, Ca writes,

How long before rain is Ranger Pro effective?


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 but at least 24 hours is the minimum.
