Weed control is crucial to the success of any garden or crop. The weeds are controlled by mechanical means, biologically, culturally, and chemically, and all methods can play a role to an integrated weed management program that is economical and environmentally friendly. Chemical control through paraquat herbicide has been a vital tool to control weeds in crops and home landscapes for years. Today's herbicides can be more selective and effective. These characteristics make them less damaging to the environment when they are used properly. Although herbicides are common but not everyone knows the way they work to manage undesirable plants. Herbicides are used to treat pests.Preemergence and postemergence are the most commonly used methods of applying herbicides. They are applied either before or after weeds emerge from the soil and begin to expand. Preemergence herbicides kill the weeds within a few days after they germinate or emerge through the soil surface. Postemergence herbicides can be used to manage weeds that are already growing and easily visible. To discover additional information on Paraquat Herbicide, you've to visit legal help site. Certain herbicides are applied to the soil and absorb by the plants that are seedlings or their roots. They are believed to be active in soil. Foliar activity is a property of herbicides that are applied to plant leaves. Certain herbicides possess both. Herbicides that have a high level of soil activity are usually applied prior to the emergence. Selectivity Selectivity refers to the way in which herbicides control or kills certain plants , but leaves others in a healthy state. Selectivity could be as simple as controlling broadleaf grass plants but not grass. The latest herbicides provide more advanced selection, and differentiate between broadleaf and grass plant species. Herbicides with no selectivity, are referred to as nonselective. They can destroy any plant. Selectivity typically depends on the duration or the location of the herbicide. Even for plants that are typically resistant to herbicides, many can cause harm if used in excessive amounts. Take Note Be cautious to avoid drift during application so that plants that aren't target aren't harmed. The application of systemic herbicides immediately following cell membrane disruptors or arsenicals that are organically produced is not advised. Both diquat and parquat are nonselective herbicides that can be harmful to broadleaf and grass plants. In peanuts, however, certain selectivity is possible through the use of paraquat during the stage of cracking. Lipid Synthesis Inhibitors Lipid Synthesis inhibitors are distinctive since they only affect perennial and annual grasses, not on broadleaf plant species. These herbicides except for diclofop (which is applied after emergence) are very low or none of soil action. To enhance the absorption of herbicides into the leaf the concentrate of crop oil or an adjuvant can be used. The herbicides should be applied on actively growing grass weeds to be the most effective. The herbicides won't perform as well if the grass weeds have a stressed growth rate.
