Great ideal ! Especially l like the can ideal. I'm a hoping it will kill the nut grass seeds growing in my vege garden.I've been fighting for over 20 years.the poisions dont work. I tried straight herbicide applyed with a art paintbrush.It worked.but.poisoned the nearby vege plants.thanks for the ideal !
