The molecular structure of S-enyl ester is C17 straight chain unsaturated fatty acid ester containing only carbon, hydrogen and oxygen, which is similar to the molecular structure of vegetable oil. In the natural environment, it degrades to vinegar-derived compounds until carbon dioxide and water; Environmentally friendly, very safe for human and non-target organisms; It has many advantages such as high activity, strong efficacy, benign non-target, environmental protection, low risk of drug resistance and no cross resistance to other pesticides.S-enyl ester is an insect growth regulator active to mosquitoes, flies, storage pests, fleas, lice, red fire ants, mushroom mosquitoes/galls and other pests. Application scenarios are as follows: Mosquito control in external environment water (recommended by WHO for controlling mosquitoes in drinking water and preventing dengue fever outbreaks), mosquito control in animal husbandry environment construction, storage pest control in grain and tobacco storage, pest control in economic field crop cultivation and storage, and control of pet parasites, etc. The mechanism of the product is to interfere with the life cycle of target insects so that they cannot develop into adults or sterility, rather than control insects with direct toxicity. Therefore, S-enyl ester is identified as a biochemical pesticide.S-enyl ester is safe, effective and feasible for industrial production of biological insecticide. In recent years, the international popular Biorational is "better to kill the young than to kill the young", which can achieve twice the result with half the effort and reduce the generation of drug resistance. The application of S-enyl ester is in line with the scientific concept of "from nature, better than nature, for nature". It is expected that S-enyl esters will continue to play an irreplaceable role in integrated vector management in the coming decades.Mechanism of action Insect growth regulatorS-enyl ester is a kind of biomimetic synthetic juvenile hormone (JH) insect growth regulator (IGRs), which is racemic in chemical structure. The larvae treated with enzoyl ester will remain in the pupal stage of development and fail to emerge into adults, effectively preventing mosquitoes from biting people and sucking blood, transmitting diseases and reproducing their offspring, thus effectively preventing the transmission of West Nile fever virus, dengue fever, Zika and other vector-borne diseases.Safe, non-toxic and greenAs a biopesticide, S-enyl ester has very low toxicity. It has been added to drinking water for vector control in the United States for a long time, and its detected toxicity is lower than that of table salt.No residual low resistance to natural decompositionS-enyl ester has a series of advantages such as green, friendly, no residue, non-toxic to human and non-target biosafety, and biosafety to target. S-enyl ester full C/H/O structure, can be naturally decomposed into H₂O and CO₂.Target strong sexThe concentration of S-enyl ester is PPB level, with strong target specificity, fast action on arthropods, and safety on mammals and non-target aquatic organisms.
