Frequently Asked Questions (FAQs)
1. What are biopesticides?
Biopesticides are pest-control agents derived from natural sources such as microorganisms, plants, animals, and naturally occurring substances.
2. What are the major types of biopesticides?
The major types of biopesticides include pathogen-based biopesticides, botanical pesticides, and biorational pesticides.
3. What are botanical pesticides?
Botanical pesticides are pest-control products obtained from plants or plant-derived substances.
4. Why is neem important as a biopesticide?
Neem contains bioactive compounds such as azadirachtin, which can act as an antifeedant, repellent, growth regulator, and oviposition deterrent for insect pests.
5. What are entomopathogenic organisms?
Entomopathogenic organisms are biological agents that cause diseases in insects. They include certain bacteria, fungi, viruses, protozoa, and nematodes.
6. What is the difference between pathogenicity and virulence?
Pathogenicity is the ability of an organism to cause disease, whereas virulence refers to the degree or intensity of its disease-causing ability.
7. What are biofertilizers?
Biofertilizers are preparations containing beneficial living microorganisms that improve nutrient availability and uptake by plants.
8. What are the main functions of biofertilizers?
Biofertilizers can fix atmospheric nitrogen, solubilize nutrients, mobilize nutrients, and promote plant growth.
9. What is biological nitrogen fixation?
Biological nitrogen fixation is the conversion of atmospheric nitrogen into ammonia by specialized microorganisms.
10. What is the difference between free-living and symbiotic nitrogen fixation?
Free-living nitrogen fixation is carried out by microorganisms living independently in the soil, while symbiotic nitrogen fixation occurs through a beneficial association between microorganisms and host plants.
11. What is the role of Rhizobium?
Rhizobium forms root nodules on suitable leguminous plants and fixes atmospheric nitrogen through a symbiotic relationship.
12. What is Azotobacter?
Azotobacter is a free-living nitrogen-fixing bacterium commonly found in soil and is used as a bacterial biofertilizer.
13. What are cyanobacterial biofertilizers?
Cyanobacterial biofertilizers contain nitrogen-fixing cyanobacteria such as Anabaena, Nostoc, and Hapalosiphon that can improve soil fertility.
14. What is mycorrhiza?
Mycorrhiza is a beneficial association between fungi and plant roots that improves nutrient and water uptake by plants.
15. What is phosphate solubilization?
Phosphate solubilization is the conversion of insoluble phosphorus compounds in soil into soluble forms that can be absorbed by plants.
16. What are potassium-solubilizing microorganisms?
Potassium-solubilizing microorganisms are beneficial microbes that help release potassium from insoluble potassium-containing minerals into forms available for plant uptake.
17. What is the difference between carrier-based and liquid biofertilizers?
Carrier-based biofertilizers contain microorganisms mixed with a solid carrier material, whereas liquid biofertilizers contain microorganisms suspended in a suitable liquid formulation.
18. What is FCO in relation to biofertilizers?
FCO stands for Fertiliser (Control) Order, which provides regulatory standards and quality specifications for fertilizer and biofertilizer products in India.
19. What factors influence the efficacy of biofertilizers?
Biofertilizer efficacy is influenced by microbial strain, product quality, soil pH, temperature, moisture, crop compatibility, storage conditions, and application methods.
20. Why are proper storage and shelf life important for biofertilizers?
Biofertilizers contain living microorganisms, so proper storage is necessary to maintain their viability and effectiveness throughout their recommended shelf life.
