Metarhizium anisopliae for Tea Plantation Pest Management in Assam | Biological Biopesticide Supplier India

Tea plantations in Assam experience warm temperatures, high humidity and substantial rainfall, creating conditions that support tea cultivation while also allowing several insect pests to persist within plantation ecosystems.

Metarhizium anisopliae is an entomopathogenic fungus widely used as a microbial biopesticide for biological management of susceptible insect pests. It is particularly valuable in programs targeting insects associated with the soil, root zone and other environments where susceptible pest stages occur.

For Assam tea plantations, Metarhizium can be incorporated into an Integrated Pest Management (IPM) strategy alongside pest monitoring, cultural practices, biological control and other compatible crop-protection measures.

How Metarhizium anisopliae Works

Metarhizium infects susceptible insects primarily through contact.

Viable fungal conidia attach to the insect's external surface. Under suitable environmental conditions, the spores germinate and the fungus can penetrate the insect cuticle.

After penetration, the fungus develops within the host and ultimately may cause insect mortality.

Because this is a biological infection process, Metarhizium generally does not provide the rapid knockdown associated with many conventional insecticides.

Metarhizium in Integrated Pest Management

Metarhizium works best as part of a structured IPM program rather than as the only response to severe pest pressure.

Tea plantation IPM can incorporate:

Regular pest scouting and identification, cultural management, plantation sanitation, conservation of beneficial organisms, microbial biopesticides and registered conventional interventions where necessary.

Repeated monitoring after application helps determine whether additional management is required.

Metarhizium and Beauveria bassiana

Both Metarhizium anisopliae and Beauveria bassiana are entomopathogenic fungi, but they should not automatically be treated as interchangeable.

Different strains may have different host ranges and environmental preferences.

A biological pest-management program may use one or both organisms depending on the target pest and field situation.

Metarhizium and Bacillus thuringiensis

Bacillus thuringiensis (Bt) products are microbial insect-control products with different modes of action and target groups from Metarhizium.

Where appropriate and legally permitted, different microbial agents may be incorporated into an IPM program according to the target pest.

Selection should be based on pest identification rather than simply combining multiple microbial products.

Available Formulations
