Yesterday I sprayed glyphosate 41% over 4.5 acres. If I sprayed yesterday at 11am and finished by 1 p.m. and didn't get rain until the overnight hours will I be fine or will I need to spray again? Also, how much glyphosate 41% do you guys normally put into a 25 gallon sprayer full of water? For those of you who have planted soybeans have you guys had good luck with broadcasting and then dragging in with a harrow? Anybody have any tips or advice? This is my first time planting beans. Thanks
