Spirotetramat 螺虫乙酯
Introduction: Spirotetramat is an insecticide derived from tetramic acid, a systemic material, for the control of sucking insects in their juvenile, immature stages, including aphids, scale insects, and whitefly. It produces growth inhibition of younger insects, reduces the ability of insects to reproduce, resulting in mortality. It acts to inhibit the biosynthesis of lipids and represents a new alternative for the control of problematic insects such as Planococcus ficus and Aphis gossypii.

ENVIRONMENTAL FATE
Spirotetramat had a half-life of 32.5 days at pH 4 and 13.1 days at pH 7 at 20℃. In a sterile buffer solution of pH 5.0, spirotetramat degraded with a half-life of 14.4 days. In a natural water at pH 7.9, the half-life was 0.74 days. It was not possible to assess the rate of photodegradation of spirotetramat on moist soil because most degradation was due to microbial activity (which was more active under dark conditions).
Usage: Spirotetramat was developed by Bayer. It is a new insecticide for the control of a wide range of sucking insects on crops such as fruit and potatoes.
Application: Spirotetramat is highly efficient and with broad spectrum, which can effectively prevent and suck all kinds of piercing mouthparts pests, such as aphids, thrips, psylla, mealybugs, whitefly, scale insects and so on. The main crops that can be applied include cotton, soybeans, citrus, tropical fruit trees, nuts, grapes, hops, potatoes and vegetables. Studies have shown that it has good selectivity for important beneficial insects such as ladybugs, hoverflies and parasitoids.
