How long does it take for 2 4 D to work

Weeds are a major yard killer. They make your yard look messy no matter how much time you spend mowing it. They prevent your sod from having that perfect Jones’s look that increases your home’s curb appeal. While you can pull them with a weed grabber, it will be hard work especially if your lawn is huge.

2 4 D known as 2,4-Dichlorophenoxyacetic acid in full mimics the action of the plant growth hormone auxin which in turn leads to the death of the weeds. 2 4 D is used to make over 1500 types of herbicides and it can be sprayed on lawns, farmlands, pastures, and orchards as well. It is an organic compound making it ideal to use for all types of crops.

  • I asked my farmer friend the same question today and he told me no. Said for lawns that might make it too “hot”. Too potent in other words I guess.
