I sprayed my plots today with 250 gallons of generic Roundup (Tractor Supply brand). As I was leaving, rain was threatening. I am not sure if it rained where I sprayed, but there was rain in the area. It would have started several hours after I finished. My question is: how long does Roundup have to stay in contact with folliage to be effective? Would a light rain several hours after application cause ineffective results? This rain was unexpected. Hope I did not waste 5 gallons of herbicide!
