Garlic produces inhibitory effect on gram-negative germs of typhoid, paratyphoid and enteritis group. It possesses outstanding germicidal properties and all cultures destroyed under their influence.
Biopesticides have been shown to be effective in controlling pests that have developed resistance to chemical pesticides, leave little or no toxic residues and are generally harmless to beneficial insects and other non-target organisms.
A major benefit is that they are safe for use by humans and they represent a very much reduced hard in terms of disposal and reuse of packaging than chemical pesticides.
Their formulation requirements are more stringent than those for chemical products. The active ingredient is often a living organism, which must be kept alive and in good health in order to achieve the desired effect.
They may also be critical nutritional or physical requirements for the organism maintenance.
