Flashcards
0/15
Pseudomonas
Biocontrol against root and seed pathogens, promotes plant growth, and can solubilize minerals like phosphates.
Potash Mobilizing Bacteria
Mobilizes insoluble potash in the soil, making it available to plants, enhancing growth and yield.
Azotobacter
Fixes nitrogen in the soil, enhances soil nutrient content, and can also produce natural growth-promoting substances.
Silicate Solubilizing Bacteria
Dissolves silicates in the soil, releasing nutrients, particularly potassium, and can also help in controlling soil pathogens.
Mycorrhizae
Enhances nutrient and water absorption, increases resistance to pathogens, and improves soil structure.
Saccharomyces cerevisiae
Used as a biofertilizer, it can increase soil nutrient content and has shown to stimulate plant growth.
Trichoderma
Biocontrol agent against various plant pathogens, promotes plant growth, and enhances nutrient uptake.
Beauveria bassiana
Entomopathogenic fungus used as a biological pesticide against a wide range of insect pests.
Rhizobium
Nitrogen fixation in legumes, leading to improved soil fertility and reduced need for chemical fertilizers.
Sulfur Oxidizing Bacteria
Oxidizes sulfur to sulfates, which are essential to plant nutrition, aiding in protein synthesis and enzyme activation.
Bacillus thuringiensis (Bt)
Used as a microbial insecticide, it produces toxins that are harmful to certain insects but safe for plants and animals.
Azospirillum
Nitrogen fixation, growth promotion through phytohormones, and can help plants in stress environments.
Phosphate Solubilizing Bacteria (PSB)
Solubilizes insoluble phosphate, making it accessible to plants, which can lead to increased yield.
Blue-green Algae (Cyanobacteria)
Contributes to nitrogen fixation, rebuilds soil organic content, and helps in reclaiming saline-alkali soils.
Nitrogen-Fixing Cyanobacteria
Particularly important for paddy fields, fixes atmospheric nitrogen and contributes to soil fertility.
