2. INTRODUCTION:
• Microorganisms toxic effects on crops
• Pest control techniques
• Biological control
• Chemical control
• Cultural control
• Mecganical & Physical control
• Genetic control
• Sterile insect techniques
3. TITLE ROLE IN MODERN AGRICULTURE:
• Safeguarding crops
• Preventing from disease
• Major crops
• Wheat:
• Ladybug & aphid
• Fungi & soil borne pathogens
• Rust fungi & Armyworms
• Yield percentage: 5-20℅
4. • Rice:
• Trichogramma wasp & Rice stem borers
• Spider, mirid bugs & Brown planthopers
• Combination with IPM and chemical control.
• YIELD percentage: 5-20℅
• Maize:
• Corn borers & trichogramma
• Spider & armyworms
• Entomopathogenic nematodes & Weevils
• Yield percentage: 5-25℅
5. • Current Scenario of Pakistan’s Various Yield Levels and Gaps:
• Conclusion:
• Importance of biological pest control processe
• Comparison of adopters & non adopters.
