A liquid formulation for applying to aerial parts of plants comprising a non-arthropod systemically acting pesticide； and carrier particles including at least an outer surface comprising an organic matter constituent, wherein said pesticide is combined within and/or on the surface of the carrier particles, the carrier particles being in particulate form and capable of carrying an electrostatic surface charge. Preferably, the carrier particles comprise a natural wax, synthetic wax, or mineral wax； most preferably a carnauba wax. The pesticide is preferably a systemically-acting fungicide, herbicide or plant growth regulator, most preferably it is selected from quizalofop-p-ethyl, prosulfocarb or azoxystrobin. Also disclosed is a composite particle comprising a non-arthropod systemically-acting pesticide； and a carrier particle including at least an outer surface comprising an organic matter constituent, wherein said pesticide is selected from at least one herbicide or chemical fungicide, the pesticide being combined within and/or on the surface of the composite particle, the composite particle being capable of carrying an electrostatic surface charge. The use of said formulation in application to aerial parts of plants is also disclosed. The systemically-acting pesticides of the invention are taken up by the aerial parts of the plant, crossing the plant cuticle.
