Garlic - other uses
Protection for plants
Garlic extracts have also been used as deterrents. In Europe these extracts are freeze dried and marketed as garlic pellets. The pellets are dissolved in water and then sprayed onto plants to protect them from being attached by greenfly or caterpillars. A disadvantage of these extracts is that the active sulphurous compounds have a pungent smell and this smell can mask the perfume of roses and other aromatic plants.
