Spirodiclofen is a potent tetronic acid derivative, belonging to the ketoenol group of insecticides/acaricides. Its unique mode of action involves the inhibition of lipid biosynthesis, specifically affecting acetyl CoA carboxylase (ACC). ACC is a crucial enzyme responsible for the production of fatty acids, which are vital components for energy storage, membrane synthesis, and various metabolic processes in pests. This disruption of fat metabolism leads to irreversible metabolic and physiological damage in mites and insect pests, resulting in their eventual demise. It is particularly effective against all developmental stages of mites, including eggs, nymphs, and adults, offering comprehensive control. The compound exhibits strong translaminar activity, meaning it penetrates leaf surfaces to provide protection on both upper and lower sides, reaching pests that might otherwise be missed by surface-applied treatments. This ensures thorough coverage and sustained protection, even in dense crop canopies. The low volatility of spirodiclofen further contributes to its long residual activity on the plant surface, providing extended protection against re-infestation.

Here are answers to some common professional questions regarding spirodiclofen, addressing its technical aspects, application, and safety profiles:
Spirodiclofen primarily acts as a lipid biosynthesis inhibitor (IRAC Group 23). It specifically targets acetyl CoA carboxylase (ACC), an enzyme critical for fatty acid synthesis in mites and insects. By inhibiting ACC, it disrupts the production of lipids essential for growth, development, and reproduction, leading to the eventual death of the pest. This unique mode of action makes it highly effective against pests that may have developed resistance to other chemical classes, making it a valuable tool in modern resistance management strategies.
Spirodiclofen is highly effective against a broad spectrum of economically important mites, including various species of spider mites (e.g., Two-spotted spider mite, European red mite, Citrus red mite), rust mites (e.g., tomato rust mite, citrus rust mite), and broad mites. It also provides good control against certain whitefly species (e.g., greenhouse whitefly, tobacco whitefly), particularly their immature stages (eggs and nymphs), disrupting their life cycle and preventing population build-up.
The most common and effective formulation is the Suspension Concentrate (SC), such as spirodiclofen 24 SC, containing 240 grams of active ingredient per liter. SC formulations offer several advantages: they are easy to measure and mix with water, provide excellent suspension stability in the spray tank, minimize dust exposure during handling, and ensure uniform spray coverage on plant surfaces, leading to consistent efficacy. Other formulations like Wettable Powder (WP) may also be available, but SC formulations are generally preferred for their superior performance characteristics.
Spirodiclofen is an excellent tool for IPM due to its unique mode of action, low toxicity to many beneficial insects and predatory mites, and strong translaminar activity. It should be used rotationally with other chemistries from different IRAC groups to prevent the development of resistance in target pest populations. Its ovicidal and nymphicidal activity also helps in breaking the pest life cycle early, reducing overall pest pressure and minimizing the need for broad-spectrum insecticides, thus supporting a more sustainable approach to pest control.
The re-entry interval (REI) for spirodiclofen varies depending on the specific product label, local regulatory requirements, and the crop being treated. Typically, REIs can range from 12 hours to several days (e.g., 24-48 hours) to ensure worker safety. It is crucial to always consult the product label for the precise REI applicable to your specific region and crop, as well as any personal protective equipment (PPE) requirements, to ensure compliance and safety for agricultural workers.
Under optimal storage conditions (cool, dry place, out of direct sunlight, in original sealed container111s), DFC Chempest's spirodiclofen 24 SC typically has a shelf life of at least 2 years from the date of manufacture. We conduct accelerated stability tests and real-time storage studies to confirm this shelf life, ensuring product efficacy and stability over extended periods. Proper storage is essential to maintain the product's quality and effectiveness.
In general, spirodiclofen has good compatibility with most commonly used fungicides, insecticides, and foliar fertilizers. However, compatibility can sometimes be influenced by water quality (pH, hardness) and the specific formulations of other products. It is always highly recommended to perform a small-scale compatibility test (jar test) before tank-mixing with other products, especially when unfamiliar combinations are used, to prevent potential physical incompatibility (e.g., flocculation, layering) or chemical reactions that could lead to reduced efficacy or phytotoxicity. Always refer to the product label for specific compatibility guidelines and warnings.
