Description

Technical Field

[0001] The invention belongs to the technical field of pesticide killing, and particularly relates to an insecticide and acaricide composition containing a tetronic acid compound and application thereof. Background Art

[0002] Spirocyclic tetronic acid compounds are lipid biosynthesis inhibitors. Their unique chemical structure, novel mode of action, outstanding control efficacy, and resistance to resistance have distinguished them from numerous other insecticides and acaricides, making them a hot topic in global insecticide and acaricide research and development. The International Insecticide Resistance Action Committee (IRAC) classifies them as Category 23 inhibitors of acetyl-CoA carboxylase, an enzyme that helps insect pests (mites) synthesize essential fatty acids during their growth. Tetronic acid compounds inhibit the activity of ACCase, a key enzyme in the fat synthesis process in insects, disrupting lipid synthesis and blocking normal energy metabolism, ultimately leading to their death.

[0003] Long-term use of pesticides inevitably leads to resistance, and spirocyclic tetronic acid compounds are no exception. Reports of resistance have been reported both domestically and internationally. Therefore, to extend the useful life of these compounds, combining them with insecticides and acaricides that exhibit negative cross-resistance can effectively reduce the risk of resistance and slow its development.
