4. Klasifikasi Berdasarkan Tipe Translokasi Herbisida dalam Tumbuhan
Secara umum herbisida dapat dibagi dalam dua golongan, yaitu herbisida kontak (tidak ditranslokasikan) dan sistemik (ditranslokasikan).
a. Herbisida kontak
Herbisida kontak dapat mengendalikan gulma dengan cara mematikan bagian gulma yang terkena/kontak langsung dengan herbisida karena sifat herbisida ini tidak ditranslokasikan atau tidak dialirkan dalam tubuh gulma. Semakin banyak organ gulma yang terkena herbisida akan semakin baik daya kerja herbisida tersebut. Oleh sebab itu, herbisida kontak umumnya diaplikasikan dengan volume semprot tinggi (600-800 L ha-1) sehingga seluruh permukaan gulma dapat terbasahi. Daya kerja herbisida tersebut kurang baik bila diaplikasikan pada gulma yang memiliki organ perkembangbiakan dalam tanah, seperti umbi (teki) atau rizom (alang-alang) karena bagian tersebut tidak dapat terjangkau oleh herbisida, atau mata tunas pada ruas rumputan yang tertutup oleh pelepah daun. Sedangkan kelebihan yang dimiliki adalah daya kerjanya cepat terlihat. Herbisida ini umumnya diaplikasikan secara kontak bersifat selektif, seperti oksifluorfen, oksadiazon, dan propani, dan sebagian herbisida lainnya bersifat tidak selektif seperti paraquat dan glufosinat.

4. the classification based on the type of Translocation of herbicides in plants In General herbicides can be divided into two classes, namely herbicides contact (not ditranslokasikan) and systemic (ditranslokasikan). a contact Herbicide.Contact herbicides to control weeds and how to turn off the affected part of the weed/herbicide because of direct contact with the nature of the herbicide is not ditranslokasikan or not streamed within the body of weeds. The more organs affected weed herbicide will be the better the herbicides work power. Therefore, contact herbicides are generally applied with a spray high volume (600-800 L ha-1) so that the entire surface of the weeds can be terbasahi. The power of these herbicides work less well when applied on weeds that have organs of breeding in the soil, such as tubers (teki) or rizom (alang-alang) because that part can not be reached by the herbicide, or eye shoots on roads covered by herbaceous stem of leaves. While the advantages of belonging to his power is quickly noticeable. The herbicide is commonly applied in contact are selective, such as oksifluorfen, oksadiazon, and propani, and some other are not selective herbicides like paraquat and glufosinat.

4. Classification by type of herbicide Translocation in Plants
In general, herbicides can be divided into two groups, namely contact herbicide (not translocated) and systemic (translocated).
a. Contact herbicide
can contact herbicides control weeds by turning off the affected part weeds / direct contact with herbicides because nature is not translocated herbicides or weed is not discharged in the body. The more organs affected weed herbicides, the better the workings of the herbicide. Therefore, contact herbicides are generally applied with high spray volumes (600-800 L ha-1) so that the entire surface of the weeds can be wetted. Herbicide working power is less good when applied to weeds which have breeding ground organs, such as tubers (puzzle) or rhizomes (reeds) because that section can not be reached by the herbicide, or buds on the grass-covered roads by the leaf midrib. While the advantages are fast acting power visible. These herbicides are generally applied selective contacts, such as oksifluorfen, oksadiazon, and propani, and some others are not selective herbicides such as paraquat and glufosinate.
