 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
Bioherbicide 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

20. 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.

21. 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.
