Provided is a formulation including an agriculturally acceptable carrier and liposomes including a lipid membrane and an intraliposomal aqueous core. The liposome has a diameter in the range of between 100 nm to 300 nm and the lipid membrane includes at least one liposome forming phospholipid. The lipid membrane may include two or more phospholipids. At least one of the two or more phospholipids may be a liposome forming lipid. Further, at least one of the two or more phospholipids may be characterized by one or more of the following features: (a) it has an unsaturated lipid tail; (b) it includes a polar head group; (c) it includes an acidic head group. Further provided are methods of using the formulation for agricultural treatment and kits for preparing and using such formulations.
