Liquid Corn Gluten Meal is an efficient organic alternative used to replace chemical pre-emergents.
Pre-emergent herbicides contain powerful chemicals such as ditopyr, oryzalin and pendimethalin which prevent seeds from being able to germinate properly.
Farmers and gardeners alike make use of pre-emergent herbicides by spraying their fields in order to thwart the growth of crabgrass, which commonly grows on bare plots of land.
Unfortunately, while these toxic chemicals can be effective in preventing the growth of weeds, they also can be harmful for the soil structure. Some are so strong that it can take up to three months after application one still can't plant seed.
Sustainable farms and organic growers like to use ground cover like mulch or a a cover crop. But sooner or later it seems that we all need a bit of help keeping weeds in check.

As is the case with tradition pre-emergent herbicides that use chemicals, in order maximum results the timing of is absolutely critical.
Application at a date too late will be less effective, since the stage in which it is effective is during the germination process.
