Biopesticide

  1. 1. Bio-pesticide Presented By Bijaya K. Uprety Department of Biotechnology Student Id: 0575751
  2. 2. Introduction • “A form of pesticide based on micro-organisms or natural products”. • Includes  microorganisms naturally occurring substances pesticidal substances produced by genetically modified plants. 1
  3. 3. Types of Bio-pesticides Sl. No Types Active Ingredients/ Substances it includes Example 1. Microbial pesticides Bacterium, fungus, virus or protozoan. Strains of Bacillus thuringiensis (Bt). 2. Biochemical pesticides/ herbal pesticides Naturally occurring substances Scented plant extracts. 3. Plant- Incorporated- Protectants (PIPs) Genetic material/ toxin Plant producing Bt toxin. 2
  4. 4. Dipel DF (Bacillus Thuringiensis var kurstaki) 1. Brand Name : Dipel DF 2. Active Ingredients: Bacillus thuringiensis var kurstaki 3. Application: Spray as a suspension. 4. Target pests: Loopers , Leaf eating caterpillars, Fruit borers & other Lepidopterous pests. 5. Crops: Vegetables, Forage crops, Aromatic crops, Ornamental. 3
  5. 5. Mode of Action Fig. Showing the mode of action of crystals produced by bacillus thuringiensis 1. http://muou.sc.mahidol.ac.th/images/mechanism_bt.jpg 4
  6. 6. Large scale production of microbial pesticides Isolation & Screening of Mo’s Fermentation Formulation as powder, suspension 5 Fig. General flow chart showing the large scale production of microbial pesticides
  7. 7. Few microbial pesticides available in market 6
  8. 8. Biochemical/Herbal pesticides • Kills pest by non toxic mechanism. • Includes,  Insect attractant/ repellant  Insect sex pheromones  Plant extracts 7
  9. 9. Mode of action of pheromones 8
  10. 10. Plant Incorporated protectants (PIP) 1. http://permaculturenews.org/2012/08/14/bt-toxicity-confirmed-flawed-studies-exposed/ 9 Fig. Showing the mode of action of cry protein crystal produced by genetically modified plant
  11. 11. How PIP producing plants are prepared???? 1. http://extension.missouri.edu/publications/DisplayPrinterFriendlyPub.aspx?P=NCR553 10
  12. 12. Advantages • No harmful residues. • Specific to target pest and closely related organisms. •Often effective in very small quantities and often decompose quickly. • High yield & reduction of use of conventional pesticides. • Improve food quality. 11
  13. 13. Disadvantages • Slow effect • Often Variable efficacy • High Selectivity • Storage • Difficulty for large scale productions 12
  14. 14. Present & Future Market Expected Global market value by 2019  $4,369.88 Million $1.6 billion in 2009, $3.3 billion in 2014 Annual Growth Rate -15.6% http://www.bccresearch.com/pressroom/chm/global-market-biopesticides-expected-increase-$3.3-billion-2014 13
  15. 15. Conclusion • Bacteria, Fungus and Virus  Mainly studied as potential bio-pesticides • Growing market • Host specific & Biodegradable • Solution to problem of food security 14
