2.5.1 Klasifikasi Herbisida
Sifat kimia herbisida tidak hanya menentukan daya kerja herbisida pada gulma yang dikendalikan (efikasi), tetapi menentukan pula tingkat keracunan (toksisitas) pada organisme nontarget misalnya tanamannya, daya tahan herbisida untuk tetap dalam keadaan aktif dalam tanah atau tumbuhan (persistensi), serta tingkah laku dan nasib herbisida di lingkungan. Hal – hal lain yang berkaitan dengan keselamatan penggunaan herbisida dan proses pendaftaran (registrasi) juga perlu mendapatkan perhatian (Sembodo, 2010). Riadi (2006) mengklasifikasikan herbisida menjadi beberapa kelompok yaitu berdasarkan perbedaan derajat respon tumbuh– tumbuhan terhadap herbsida (selektivitas), pada waktu aplikasinya, media atau jalur aplikasinya, tipe translokasi herbisida dalam tumbuhan, tipe translokasi herbisida dalam tumbuhan, dan golongan bahan aktif herbisida.

2.5.1 the classification of Herbicides The nature of chemical herbicides not only determine the working power of herbicides on weed-controlled (efficacy), but also determine the level of toxicity (toxicity) on nontarget organisms such as plants, durability of herbicides to keep in a State of active in the soil or plant (persistence), as well as the behavior and fate of herbicides in the environment. Things – other matters relating to the safety of the use of herbicides and the registration process (register) will also need to get attention (Sembodo, 2010). Riadi (2006) classifies the herbicide into several groups, based on differences in the degree of response of a plant to grow – herbsida (selectivity), at the time of the application, the application path, or media types in plants, herbicides translocation types of translocation of herbicides in plants, and the active ingredients in the herbicides.

2.5.1 Classification of Herbicides
herbicide chemical properties not only determine the workings of herbicides on weeds controlled (efficacy), but also determine the level of toxicity (toxicity) on nontarget organisms such plants, herbicide resistance in a state to remain active in the soil or plants (persistence ), as well as the behavior and fate of herbicides in the environment. It - other matters relating to the safety of the use of herbicides and the process of registration (registration) also deserve attention (Sembodo, 2010). Riadi (2006) classifies herbicides into several groups, based on differences in the degree of response of vegetation to herbsida (selectivity), at the time of application, media or track application, the type of herbicide translocation in plants, the type of herbicide translocation in plants, and the class of herbicide active ingredient.
