Description
Pyridalyl was introduced by Sumitomo in 2004 for the control of Lepidoptera and thrips. It is highly selective for these orders, a preferred characteristic in integrated pest management programs. It appears to have a new mode of action and is active against insects resistant to other compounds.
Uses
Pyridalyl is an insecticide used on Bracon mellitor Say, Cardiochiles nigriceps Viereck, Coleomegilla maculata De Geer, Cotesia marginiventris (Cresson), Geocoris punctipes (Say), and other cotton insect pests.
Definition
ChEBI: Pyridalyl is an organochlorine insecticide, an organofluorine insecticide and a dichlorobenzene.
Mode of action
Pyridalyl is selectively cytotoxic to cells of target species, by an unknown mechanism.
Toxicity evaluation
Pyridalyl has low toxicity to non-target organisms. However, because it has a high potential for bioaccumulation and is persistent in soil, sediment and water, and may accumulate with repeated use, it is only approved in the U.S. for greenhouse use.
