Herby Pesiticides

Common herbs and spices show promise as an environmentally-friendly alternative to conventional pesticides, scientists have told a major US conference.

They have spent a decade researching the insecticidal properties of rosemary, thyme, clove and mint.

They could become a key weapon against insect pests in organic agriculture, the researchers say, as the industry attempts to satisfy demand.

The "plant essential oils" have a broad range of action against bugs.

Some kill them outright while others repel them.
