• Ability to multiply in the target cells.
• Permanent control of pest or long persisting effect.
• No fear of environment pollution and hence ecofriendly.
• Biopesticides are usually inherently less toxic than conventional pesticides.
• Biopesticides generally affect only the target pest and closely related organisms, in contrast to broad spectrum, conventional pesticides that may affect organisms as different as birds, insects and mammals.
• Biopesticides often are effective in very small quantities and often decompose quickly, resulting in lower exposures and largely avoiding the pollution problems caused by conventional pesticides.
