General description

Spirodiclofen is a selective, non-systemic acaricide from the new chemical class of tetronic acid derivatives. It shows activity against all developmental stages of female adults of tetranychid mite species such as the two-spotted spider miteTetranychus urticae.

Application

Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.
Spirodiclofen may be used as analytical reference standard for the determination of the pesticide, spirodiclofen in crops using high-performance liquid chromatography coupled to tandem mass spectrometry (HPLC-MS/MS).

Pesticide resistance arises rapidly in arthropod herbivores, as can host plant adaptation, and both are significant problems in agriculture. These traits have been challenging to study as both are often polygenic and many arthropods are genetically intractable. Here, we examined
