Pymetrozine: A Novel Insecticide Affecting Aphids and Whiteflies

Pymetrozine is a new insecticide, highly active and specific against sucking insect pests. Pymetrozine is the only representative of the pyridine azomethines, a new class of insecticides, and is currently being developed worldwide for control of aphids and whiteflies in field crops, vegetables, ornamentals, cotton, hop, deciduous fruit, and citrus, and of the brown planthopper, Nilaparvata lugens (Staol), in rice. The compound appears to have great promise in integrated pest management (IPM) programs due to its high degree of selectivity, low mammalian toxicity, and safety to birds, fish, and nontarget arthropods. Pymetrozine was discovered and is currently being registered and marketed by Ciba-Geigy with the tradenames “Fulfill”, “Relay” and “Sterling” in the USA and “Plenum” or “Chess” elsewhere.
