2. Herbicid e
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
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:
18. Mycho Tech
Target Weed specie: Deciduous Plants
Name of Microbe :Chondrosterium purpurium
19. StumpOut TM
Target Weed specie: Acacia spp. Prunus
serotina
Name of Microbe : Chyndrostereum
purpurium
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.
