Tom writes,

I just had my drainage ditch cleaned and I want to apply Killzall. How long will the application last?


Killzall Weed and Grass Killer will only kill the plants and weeds that are sprayed directly. Killzall will not prevent furture plants or weeds from growing as it is only effective when it is first applied.
