Chemical Class:
Diafenthiuron is an aromatic ether, specifically a thiourea acaricide and insecticide.
Mechanism of Action:
It acts by inhibiting oxidative phosphorylation in the mitochondria of target pests, leading to paralysis and death.
Solubility:
It is highly soluble in organic solvents but has low aqueous solubility, meaning it's unlikely to leach into groundwater.
Persistence:
It is not persistent in most soil systems but may persist in aquatic systems.
Toxicity:
It has low mammalian toxicity but can be moderate to highly toxic to aquatic life, bees, and worms.
Uses and Applications:
Target Pests: Effective against a wide range of sucking pests and mites, including aphids, whiteflies, thrips, jassids, and spider mites.
Crops: Used in various crops, including cotton, fruit trees, ornamentals, and soybeans.
Formulations: Available in various formulations, including 50% WP and 47.8% w/w SC.
Brand Names: Sold under brand names like Derby, Diron, Pegasus, Polar, Polo, and Pager.
Other names: 1-tert-Butyl-3-(2,6-diisopropyl-4-phenoxyphenyl)-thiourea, N-[2,6-Bis(1-methylethyl)-4-phenoxyphenyl]-N-(1,1-dimethylethyl)-thiourea
