Herbaceous plants can produce millions of seed, which infest the soil and will germinate over a number of years. You need to identify the weed species in your field and their growth habits before you can develop ways to control them. The use of one particular method, whether chemical or cultural, will reduce some species while encouraging others. It is therefore necessary to develop an integrated approach, combining both chemical and cultural methods. The three main objectives of integrated weed management are prevention, control, and eradication.
Prevention involves keeping weeds from being introduced in uninfested areas.
Control is the suppression of a weed to the point that its economic impact is minimized. Eradication is the elimination of all weed plants and plant parts from an area. It is important to remember that a single treatment of any weed control method will not control all the weeds that are present. A successful weed management program incorporates both chemical and cultural methods to achieve objectives. Prevention Prevention involves preventing the spread of weed seed or vegetative parts and stopping emergence of weed seed present in the soil.
