Weed Killer in granular form offer a more targeted application in places where wind and rain inhibit liquid weed killers effectiveness.
When applying Granular weed killer make sure you do it before a big rain so that the granules breakdown and enter the soil. Lots of irrigation could also be necessary in places where the soil does not absorb well ie. clay etc.
Sometimes aeration of the soil is needed where water cannot penetrate through.
Granular weed killers and herbicides are not only used on land but also in water.
Aquatic weed killer granules are used to target aquatic weeds such as milfoil.
