Thiacloprid acts as an agonist of the nicotinic acetylcholine receptor in the central nervous system, thus disturbing synaptic signal transmissions. Mode of action Acute contact and stomach poison, with systemic properties. Used by foliar application against sucking and biting insects in pome fruit, stone fruit, small berries, cotton, vegetables, sugar beet, potatoes, rice and ornamentals. Pests controlled include aphids, whiteflies, beetles (e.g. Leptinotarsa decemlineata, Anthonomus pomorum, Lissorhoptrus oryzophilus) and Lepidoptera such as leaf miners and Cydia pomonella.
