dinotefuran

Dinotefuran is a systemic insecticide in the neonicotinoid class used to control a range of sucking pests in crops and ornamental plants. It is absorbed by plants and distributed through the vascular system, providing protection from within the treated tissue for a period after application.

Dinotefuran acts on nicotinic acetylcholine receptors in the insect nervous system, causing overstimulation, paralysis, and death. Its rapid action makes it effective against pests such as aphids, whiteflies, scale, and leafhoppers. The compound is formulated in various forms, including liquids, emulsifiable concentrates, and granules, and can be applied as a soil drench, foliar spray, or seed treatment, depending on the crop and product label.

Environmental and safety considerations: dinotefuran has low acute toxicity to humans and many mammals but can be highly toxic to bees and aquatic invertebrates. Its systemic nature and water solubility mean it can be taken up by non-target plants and may persist at low levels in plant tissues. Regulatory controls vary by jurisdiction, with some regions imposing restrictions to minimize pollinator exposure and environmental runoff. Label recommendations typically specify preharvest intervals, buffer zones near water, and required protective measures during handling and application.

Regulatory status: as a neonicotinoid, dinotefuran is subject to country-specific approvals and restrictions. Agencies assess its environmental fate, non-target toxicity, and residues, leading to differing usage patterns and safeguards across markets.
