Diafenthiuron, a novel thiourea-based insecticide and acaricide, effectively targets pests and mites with contact, stomach, systemic, and fumigation effects, while also displaying ovicidal properties. It holds low toxicity for most organisms, yet presents high toxicity towards fish and bees. When exposed to ultraviolet light, it transforms into an active insecticidal substance, demonstrating robust efficacy against pests that have developed significant resistance to other pesticides on vegetables. This broad-spectrum compound combats phytophagous mites and sucking pests including aphids, whiteflies, spider mites, diamondback moths, thrips, and jassids. Operating via contact and stomach modes of action, its mechanism involves inhibiting oxidative phosphorylation as an inhibitor of mitochondrial ATP synthase.

Application/Usage: Diafenthiuron finds its primary application on a diverse array of crops, including cotton, fruit trees, vegetables, ornamental plants, and soybeans. The recommended dosage varies within the range of 0.75 to 100 grams of active ingredient per square meter (g/m²). Notably, its sustained effectiveness endures for a duration of up to 21 days, making it a valuable tool for integrated pest management strategies. The recommended dosage varies based on the specific pest, crop type, and formulation employed. Typically administered as a foliar spray, it is advisable to apply Diafenthiuron preventively or during the initial stages of pest infestations for optimal results.
