Question on: SS2 Agriculture - Preventive and Control Measures of diseases
Discuss the advantages and disadvantages of using microbial pesticides like Bacillus thuringiensis (Bt) in pest management
Advantages:
Specificity: Bt is highly specific to certain insect pests, minimizing harm to non-target organisms.
Low Environmental Impact: Bt breaks down quickly in the environment and has a minimal impact on non-target species.
Resistance Management: Bt can be an essential tool for managing resistance as pests are less likely to develop resistance quickly.
Disadvantages:
Limited Spectrum: Bt is effective against a narrow range of pests and not all insect species.
Application Frequency: Regular applications may be necessary since Bt doesn't provide long-lasting protection.
Timing: Effective control often depends on applying Bt when pests are in their vulnerable larval stage.
Overall, Bt is a valuable component of integrated pest management but should be used in conjunction with other methods for comprehensive pest control.
