is there a gardening master here? or chemistry teacher im trying to kill some weeds in my lawn using herbicides but dont know which chemical to use its my first time im a gardening virgin my plan is to quick kill them weeds by using glufosinate ammonium base product and then sprinking some sulfentrazone base herbicides to cease the photosynthesis and let that stay for a long term so i dont have to do it until this autumn is this combo dangerous? am i going to get killed by inhaling them?
