Cypermethrin is an insecticide that has approval for use in the EU. %%EOF Pyrethroids delay the closure of the sodium channel. A professional insecticide dust that contains Zeta-Cypermethrin which is 4x more powerful than regular Cypermethrin for a quick kill and a long residual. Grid List. The unique biphenyl action binds the molecule to the soil. Cypermethrin (CP) is a synthetic pyrethroid used as an insecticide in large-scale commercial agricultural applications as well as in consumer products for domestic purposes. Zeta-cypermethrin is a contact insecticide that also works through stomach contact. Synthetic pyrethroids are man-made insecticides created to mimic the chemical properties of the naturally-occurring insecticide pyrethrum, that comes from Chrysanthemum flowers. The following list of North American Industrial Classification System (NAICS) codes is not intended to be exhaustive, but rather provides a guide to help readers Start Printed Page 45… Whereas cypermethrin refers to a racemic mixture of the alcohol and acid moiety, zeta-cypermethrin is enriched with the -alcohol and has a cis/transS ratio of 45.55 in the Zeta-cypermethrin is a mixture of stereoisomer pairs, CC1(C(C1C(=O)OC(C#N)C2=CC(=CC=C2)OC3=CC=CC=C3)C=C(Cl)Cl)C, CC1(C(C1C(=O)O[C@H](C#N)C2=CC(=CC=C2)OC3=CC=CC=C3)C=C(Cl)Cl)C, International Chemical Identifier key (InChIKey), International Chemical Identifier (InChI), InChI=1S/C22H19Cl2NO3/c1-22(2)17(12-19(23)24)20(22)21(26)28-18(13-25)14-7-6-10-16(11-14)27-15-8-4-3-5-9-15/h3-12,17-18,20H,1-2H3, Cambridge Crystallographic Data Centre diagrams, EU dossier - toluene <2g kg⁻¹, tars 12.5 g kg⁻¹.

In other words, the chemical stays where you apply it and does not leech. The ISO common name zeta-cypermethrin designates a pyrethroid that can be considered as esterification product of the (S)-α-cyano-3-phenoxybenzyl alcohol and permethric acid. It is similar to cypermethrin but has a quicker mode of action. Modes of action are colour-coded according to the physiological functions affected. You may be potentially affected by this action if you are an agricultural producer, food manufacturer, or pesticide manufacturer. Actives are allocated to specific groups based on their target site.
