How soon after I apply a combination of NyGaurd and Talstar can I water the grass? What effect does it have on the chemicals?
You generally want to wait at least 24 hours after an application of Talstar and NyGuard so that the application has time to dry and adhere to the grass and surfaces you have applied it to. Watering too much can cause the product to lose it's effectiveness over time so you would want to apply once a month.
