2. Herbicide A substance that is toxic to plants used to destroy unwanted vegetation. Herbicides belong to a group of chemicals which prevent, destroy, repel, or mitigate pest. Herbicides are any chemical substance that is used to kill plants or inhibit growth.

3. Bioherbicides Bio herbicide  is a biologically based control agent for weeds .   Bioherbicides may be compounds and secondary metabolites derived from microbes such as fungi, Bacteria or protozoa; or Phytotoxic plant residues, extracts or single compounds derived from other plant species.

4. Why Bioherbicides? In irrigated agriculture weed control through chemicals creates ; Spray drift hazards Water contamination Effects Environment Contamination in food sources i-e ( effect livings health) So Bioherbicides will be alternately used for weed control. . .

5. Characteristics for Bioherbicides Produce abundant & adorable inoculum in culture Be target specific Be genetically stable Determental effect on non-target plants (Native Plants)

6. Types of Bioherbicides Bioherbicides may be   secondary metabolites derived from microbes such as fungi, bacteria or protozoa;  Phytotoxic plant residues , extracts or single compounds derived from other plant species.

7. Available Bioherbicides While many different products have been launched, currently some Bioherbicides are available for sale/purchase in market globally . Below is the list of available Bioherbicides:

19. XPO (Xanthomonas) Xpo ( Xanthomonas bacteria) is used for Annual bluegrass control. It has a high potential as a biological control agent for perennial ryegrass( Lolium perenne L.). It is evaluated as a commercial bioherbicide.

20. Plant Extracts as Bioherbicides Plant Extract: A plant extract is a substance or an active with desirable properties that is removed from the tissue of a plant, usually by treating it with a solvent, to be used for a particular purpose.
