Getting To Know The Different Kinds Of Weed Killers

For those of you who are still pulling up weeds the old fashioned way, there are specially formulated weed killers that can make your gardening task seem less like a job and more like a hobby again.

Because there are so many different types, let's go over the different descriptions of these chemicals called herbicides.

Emergence refers to whether the herbicide can target the weeds before they've broken through the soil or not. Those can call pre-emergent and are good to use against annuals.

Annuals are weeds that grow for a season. Those that cannot and must wait for the weed to peak up through the dirt are called post-emergent. Post-emergent herbicides can be easily sprayed onto plants or soil. They won't however be effective with the underground weeds as they break down quickly in the soil.

Selectivity refers to the spectrum that the herbicide attacks. Selective weed killers will only kill their target weeds like dandelions. Non-selective, however, will attack all plant life that it comes into contact with. These are ideal for when clearing an area when you plan on re-planting as farmers will switch up their crops.

Persistence refers to the time of effectiveness. Non-selective, discussed above, that kill all plant life and prevent re-growth is deemed very persistent. Those that do not fight re-growth are considered non-persistent. Non-persistent herbicides break down more quickly and often require more frequent application.
