Abstract:
Disclosed are an oil-based suspension, a preparation method therefor and the use thereof. Said oil-based suspension comprises the following components: Component A: at least one spirotetramat active substance which is a solid at room temperature; Component B: at least one fatty acid ester of general formula R 1-COO-R 2 and/or R 1-COO-R 2-OOC-R 1; Component C: at least one non-ionic surfactant and/or at least one anionic surfactant; and Component D: optionally one or at least two additives selected from an emulsifier, a defoaming agent, a preservative, an antioxidant, a colourant and an inert filling material. The oil-based suspension prepared by the present invention effectively resolves the problem of particle size increase of spirotetramat during storage, greatly inhibits the particle size of suspended spirotetramat particles from increasing, increases the activity of spirotetramat, obtains a higher activity compared with conventional formulations, and reduces the use amount of spirotetramat.
