Liposomal formulations and methods of using same in agriculture

A formulation comprising:

• (i) liposomes comprising a lipid membrane and an intraliposomal aqueous core,
• wherein,
• the liposome has a diameter in the range of between 100 nm to 300 nm
• the lipid membrane comprises two or more phospholipids, and non-liposome forming lipids comprising at least one plant derived sterol and at least one saponin,
• at least one of said two or more phospholipids is a liposome forming lipid,
• at least one of said two or more phospholipids has an unsaturated lipid tail;
• and
• said lipid membrane comprises a mole % ratio between the said two or more phospholipids and the said at least one plant derived sterol and at least one saponin of between 20 mol %::80 mol % to 80 mol %::20 mol %;
• and
• (ii) an agriculturally acceptable carrier.

A method of treating a plant comprising applying to a surface of a plant part a formulation comprising

• (iii) liposomes comprising a lipid membrane and an intraliposomal aqueous core,
• wherein,
• the liposome has a diameter in the range of between 100 nm to 300 nm
• the lipid membrane comprises two or more phospholipids, and non-liposome forming lipids comprising at least one plant derived sterol and at least one saponin,
• at least one of said two or more phospholipids is a liposome forming lipid,
• at least one of said two or more phospholipids has an unsaturated lipid tail;
• and
• said lipid membrane comprises a mole % ratio between the said two or more phospholipids and the said at least one plant derived sterol and at least one saponin of between 20 mol %:80 mol % to 80 mol %:20 mol %;
• and
• (iv) an agriculturally acceptable carrier.
