After realizing what I did I sprayed the yard to dilute the chemical. Was this helpful or make it worse? How many days before seeing dieing grass?
Once a soil sterilizer like Pramitol 25E has been applied there is not much you can do to reverse the effects other than to dig out any dirt that has the product in it and replace it with clean untreated soil and replant grass in those areas. Watering it likely pushed it into the soil more as this product is designed to be watered in after application to make it work appropriately and last a long time in the soil. Since its main function is to prevent new grasses and plants in general from coming up from the soil, its slower to work on anything already growing on the surface. It could cause the grass to die in a few days or in a week or two depending on how heavily it was applied. Since a lower use rate of 2oz per gallon was used it may not last as long as if higher rates were applied. You may want to contact a lawn company and see if they have any flowable charcoal they can come spray on the lawn to try and break down the chemical or if they feel it would do any good.
