Which describes a "preplant incorporated" method?

The "preplant incorporated" method refers specifically to the technique of applying herbicides to the soil and then incorporating them through tillage before the planting of crops. This method is effective because it allows the herbicide to be mixed into the soil, which helps it work against weeds that may germinate after the crop is seeded.

By incorporating the herbicides into the soil before the crop is planted, it ensures that the active ingredients are in close contact with the weed seeds that are present in the soil, increasing the likelihood that those weeds will be controlled when they attempt to germinate. This proactive approach can improve overall weed management and reduces competition for resources such as water, light, and nutrients that the crops need to thrive.

Other methods, such as applying herbicides after the crop has emerged or monitoring weed growth, do not fall under the preplant incorporated category as they involve actions occurring after planting or observational strategies rather than proactive soil treatment prior to planting.
