| TRICHODERMA SPP |
|
Trichoderma is an antagonistic fungi act as bio-control agents for many of the plant pathogens. It has wide range of hosts. There are different species of trichoderma viz. T. viridae, T. herzianum, T. hamatum.
Trichoderma is beneficial fungus that secrets cellulytic enzymes which react with the cell wall of the disease causing fungi & dissolve it. This causes the protoplasm to flow out, which Trichoderma utilizes as a source of food & multiplies its, thus destroying the pathogenic fungi. Moreover, the secretion Trichodermain from the mycelia of Trichoderma is antagonistic to most parasitic microorganisms, rendering them inactive &, in most cases, destroying them.
How does Trichoderma protects
the plants ?
Trichoderma
fungus spreads rapidly in soil
& act against a range of
economically important aerial
& soil borne plant pathogens
by secreting some toxins &
enzymes. Trichoderma species
are ubiquitous soil fungi which
produce white , yellow or gren
colonies when cultured.

BIOPESTICIDE
BEAUVERIA BASSINA |
|
Beauveria bassiana is an eco-friendly biocontrol agent . It is used to control insect pest of economic importance. Beauveria bassiana is naturally occurring entomopathogenic fungi.
Microbial insecticide containing conidia of B. bassiana controls root & stemborers, white grubs, second &third instar caterpillar & other sucking insect in crops such as Grapes, Cotton , Pulse, Tea . Potato, Tomato, oil seeds Tobacco , Spices, Cereals, Vegetables, horticultural & ornamental crops.
When B. bassiana comes in contact with the insect pests the spores will germinate through the cuticle & multiply in the haemocoel. B. bassiana produce toxic metabolites called Beauvericin. It inhibits the metabolic enzymes and paralyses the insect leads to insect death. The dead insect is transformed into mummy (hard & solid structure) due to saprophytic development & emission of toxic metabolites by B. bassiana fungus. The insect totally covered by white mycelium of B bassiana fungus. It takes 5 – 7 days to exhibit the symptoms. High humidity helps in achieving maximum mortality.

| VERTICILLIUM LECANII |
|
Verticillium lecanii is multipurpose naturally occurring entomopathogenic fungi.
It is important bio-control agent for mealy bugs, thrips, aphids, & other sucking insect pest in crops Grapes, Cotton, Pulse, Tea, Potato, Tomato, oil seeds Tobacco, Spices, Cereals, Vegetables, horticultural and ornamental crops.
Spores after depositing on the insect cuticle penetrate in the cuticle. Penetration also occurs through the spiracles, the mouth, & anal opening. Development occurs in the hemolymph. Insect mortality due to fungal infection has been ascribed to the destruction of insect tissue, the release of toxins & nutritional deficiencies.

| METARHIZIUM ANISOPLAE |
|
Metarhizium anisoplae is an naturally occurring entomopathogenic fungi. It is also called as green muscardine fungus. Metarhizium anisoplae is reported to be capable of infecting more than 100 different insect species belonging to variety of insects orders.
It is used as bio-control agent against white grubs, termite, & other soil born insects in crops such as Grapes, Cotton, Pulse, Tea. Potato, Tomato, oil seeds Tobacco, Spices, Cereals, Vegetables, all horticultural & ornamental crops.
Infection of the fungus generally takes place through the integument. However, the exact site of infection is dependent on the stage of the insect, environmental conditions. The cuticle is penetrated with the aid of enzymes secreted at the apex of the penetrant hyphae. Penetrant hyphae give rise to hyphal bodies before death of the insect. Hyphal bodies distributed throughout the body cavity of the insect & give rise to secondary bodies. In the moist, warm environment, hyphae emerge a few days after the insect’s death, usually through the weaker part of the integument, and conidia are produced on conidiophore. This fungus also produce destruxins A, B, C, D, & E & esmethyldestruxin B, substances toxic to insect. The rapid production of destruxin in the larvae causes death of larvae.

| PAECILOMYCES SPP. |
|
Paecilomyces spp. is an important entomopathogenic fungi. It is considered as a very promising biological control agent due to extensive host range which includes insects in over 25 different families, including diamond back moth , Russian wheat aphid, & silverleaf whitefly. Some members in this genus are active plant parasitic nematode.
Mode of action is same as that of other entomopathogenic fungi described above.
