Answer to Wayne is 2-3 days. Answer to Nancy is 5-7 days. Big difference! Also after applying tenacity when can the lawn go back to its watering cycle. Both of my questions, cutting and watering either pre or post, strive to allow the best conditions to get the best per application. I must have missed reading these things in your attached literature. Thank you. Lastly when can I continue with fertilizing the lawn after an application?
When using Tenacity Herbicide or other post-emergent herbicides, you should not mow at least 2 days before or 2 days after applying the product. You should avoid spraying on newly germinated turgrass plants, and wait until newly germinated turf has been mowed 2 times or 4 weeks after emergence (whichever is longer) before applying, per the product label. Regarding watering, Tenacity is rainfast within a few hours of application, so I would avoid watering within about 3 hours of post-emergent applications. For pre-emergent applications, you will need to irrigate the area with 0.15 inches of water if there has not been this amount of rainfall within 10 days of application. There are no restrictions on fertilizing schedules. Keep in mind that desirable turf may discolor slightly to white or yellow, but listed tolerable turf should recover well. If you are using a fertilizer that can stress the lawn, then it may be a good idea to separate applications by 1-2 weeks. Please let us know if we may further assist you.
