Sutherland, IA | We like to wait 7 days but i've seen guys spray it on post plant pre-emerge before. If we're late getting are pre-emerge on we'll just leave it out. What causes problems is when you get that .10" rain and it takes it right to the seedling. A good half inch after it's on and you'll probably be fine. Dad tells me they used to spray it on with the planter back in the day but we've seen a couple people get burnt before with the .10" rain scenario. | |
