Conventional herbicides come in two main categories, post and pre-emergent. Simply put, post-emergent means that it kills the weeds around they have come out of the ground. Pre-emergent means that they sit in the soil killing the weed seed when it is germinating.
Bioweed is a post-emergent herbicide that has pre-emergent qualities. This just means that Bioweed will control the weed the is current growth but also has the power to suppress the seeds that it contacts. This is the big difference in Bioweed’s seed suppression ability - It does not have to wait in the soil for the seed to germinate to kill it but sterilizes the seed on contact. One of the biggest issues with conventional pre-emergent is that it stays in your soil for many months and can negatively affect your soil health. As Bioweed is non-residual it will suppress the seed and within 72hrs Bioweed will break down in the soil.
