Biofertilizers, Biofungicides & Biopesticides for Assam Agriculture | Microbial Agricultural Products Supplier India
Share
Assam has a diverse agricultural sector covering rice, tea, mustard, ginger, turmeric, banana, pineapple, Assam lemon and citrus, arecanut and other field, plantation and horticultural crops. High rainfall, humid conditions, acidic soils and diverse cropping systems create different requirements for crop nutrition, root-zone health, soil management, disease management and insect-pest management.
Microbial agricultural inputs provide biological tools that can be incorporated into Integrated Nutrient Management (INM), Integrated Pest Management (IPM) and Integrated Disease Management (IDM) programs.
Major categories include biofertilizers, biofungicides, biopesticides and bionematicides based on beneficial bacteria and fungi.
Biofertilizers for Assam Agriculture
Microbial biofertilizers contain beneficial microorganisms selected for specific nutrient-related functions.
Important options include:
Azotobacter — free-living nitrogen-fixing bacterium
Azospirillum — associative nitrogen-fixing bacterium
PSB — Phosphate Solubilizing Bacteria
KMB — Potassium Mobilizing Bacteria
ZSB — Zinc Solubilizing Bacteria
Silicate Solubilizing Bacteria — microbial input for silicon-related soil programs
Iron Solubilizing Bacteria — microbial micronutrient input
Sulphur Solubilizing Bacteria — microbial sulphur-management input
NPK Consortium — Azotobacter + PSB + KMB
NPK + Zinc PGPR — multi-functional microbial nutrient formulation
These products can complement conventional fertilizer and organic nutrient programs.
NPK Microbial Consortium
An NPK microbial consortium combines microorganisms associated with three important nutrient functions:
Azotobacter + PSB + KMB
This provides microbial activity associated with:
Nitrogen fixation + Phosphorus solubilization + Potassium mobilization
NPK consortia can be incorporated into integrated nutrition programs for several Assam crops.
Biofungicides for Assam Agriculture
Microbial biofungicides are beneficial microorganisms used as part of biological and integrated disease-management programs.
Important organisms include:
Trichoderma viride
Trichoderma harzianum
Trichoderma asperellum
Pseudomonas fluorescens
Bacillus subtilis
Ampelomyces quisqualis
Each organism has different biological characteristics and should be selected according to the target crop, pathogen and application system.
Trichoderma for Assam Farmers
Trichoderma spp. are beneficial fungi widely used for soil, root-zone and integrated management of susceptible soil-borne pathogens.
They can be relevant to biological programs in crops such as rice, tea, ginger, turmeric, banana, citrus, pineapple and arecanut.
Trichoderma performs best as part of a preventive program combined with good sanitation, drainage and crop management.
Pseudomonas fluorescens
Pseudomonas fluorescens is a beneficial rhizosphere bacterium widely used in biological root-zone and integrated disease-management programs.
Suitable formulations can be incorporated into soil and root-zone management programs for field, horticultural and plantation crops.
Bacillus subtilis
Bacillus subtilis is a beneficial bacterium used in microbial crop-protection programs.
Selected strains are used in biological disease-management systems and can complement other compatible microbial inputs.
Ampelomyces quisqualis
Ampelomyces quisqualis is a mycoparasitic fungus particularly associated with biological management programs targeting susceptible powdery mildew fungi.
It is a specialized microbial biofungicide and should be selected according to the target disease.
Biopesticides for Assam Agriculture
Entomopathogenic fungi and bacteria provide microbial options for managing susceptible insect pests.
Important organisms include:
Beauveria bassiana
Metarhizium anisopliae
Verticillium/Lecanicillium lecanii
Bacillus thuringiensis var. kurstaki (Btk)
Each microbial biopesticide has a different pest spectrum and mode of action.
Beauveria bassiana
Beauveria bassiana is an entomopathogenic fungus used against susceptible insect pests.
Under suitable environmental conditions, fungal spores can germinate on susceptible insects, penetrate the cuticle and establish infection.
It can form part of IPM programs in several agricultural and plantation crops.
Metarhizium anisopliae
Metarhizium anisopliae is an entomopathogenic fungus particularly useful in biological programs targeting susceptible soil-associated insects and root-feeding larvae.
It can be relevant to plantation and horticultural crop programs where suitable target pests are identified.
Verticillium/Lecanicillium lecanii
Lecanicillium lecanii, historically marketed widely as Verticillium lecanii, is an entomopathogenic fungus used in biological programs against susceptible soft-bodied and sucking insect pests.
Correct pest identification and favorable environmental conditions are important for successful application.
Bacillus thuringiensis var. kurstaki
Bacillus thuringiensis var. kurstaki (Btk) is a microbial insecticide used primarily against susceptible lepidopteran caterpillar larvae.
Applications generally perform best when susceptible larvae are actively feeding and treatments are timed appropriately.
Bionematicides for Assam Agriculture
Plant-parasitic nematodes can affect root development and crop performance.
Biological nematode-management options include microorganisms such as:
Purpureocillium lilacinum / Paecilomyces lilacinus
Pochonia chlamydosporia
Bacillus firmus
These microorganisms can be incorporated into integrated nematode-management programs where appropriate.
Paecilomyces / Purpureocillium lilacinum
Purpureocillium lilacinum, commonly known in agricultural trade by its former name Paecilomyces lilacinus, is used in biological nematode-management programs.
It is primarily intended for soil and root-zone application.
Pochonia chlamydosporia
Pochonia chlamydosporia is a beneficial fungus studied and used in biological programs targeting certain plant-parasitic nematodes.
It can form part of preventive root-zone management strategies.
Bacillus firmus
Bacillus firmus is a beneficial bacterium used in certain microbial nematode-management products.
Suitable formulations can be integrated with other agronomic and biological practices where nematode pressure is identified.
Liquid Microbial Products
Liquid formulations can be convenient for commercial farms, plantations and irrigation-based application systems.
Depending on formulation, microbial products may be suitable for soil drenching, root-zone treatment or compatible drip-irrigation applications.
Wettable Powder Products
Wettable powder formulations can provide practical options for soil, root-zone and crop-protection applications.
Application methods should follow the specific microorganism, formulation and product recommendations.
Water-Soluble / Dextrose-Based Products
Suitable water-soluble microbial powder formulations can be useful where rapid dispersion in water is required.
Users should verify compatibility with irrigation equipment and other agricultural inputs before application.
Talc-Based Microbial Products
Talc-based microbial formulations are commonly used for soil application, root-zone treatment and incorporation with suitable organic carriers.
They should not automatically be assumed suitable for every drip or spraying system.
